Class 40 Mighty Mites

• By James Boyd
• May 23, 2023

For sailing fans visiting from ­outside France, the Route du Rhum is a cultural shock, barely to be believed even once seen. It is France’s oldest singlehanded race, first held in 1978, and run every four years from St. Malo in northern France 3,500 miles across the North Atlantic to Guadeloupe. The fleet of 138 boats that assembled for the start in November 2022 was incredible, with an estimated value of 260 million euros—from the implausible 100-foot Ultime trimarans to a record fleet of 38 IMOCA 60s and a similarly impressive fleet of 55 Class40s. Dock sides are crammed with spectators, many hoping to catch a glimpse of the top skippers—some are genuine sports stars. Had the 2022 start not been delayed, French President Emmanuel Macron was to have attended. It’s that much of a big deal.

In the days and hours before the Route du Rhum started, more than 1 million people passed through its race village in St. Malo. In this environment, even non-French amateurs, such as the two US Class40 skippers, Alex Mehran and Greg Leonard, gained celebrity status with relentless autograph signing, selfies with fans and press interviews. Usually outshone by the bigger, higher-profile boats, the Class40 is the most successful 40-footer of all time. While the Farr 40 never topped more than 40 boats at a world championship, this is the second Route du Rhum in which more than 50 participated. To date, 192 Class40 hull numbers have been allocated.

While “Open 40s” once competed in the OSTAR and Around Alone, the Class40 came about independently. Born in France in the early 2000s, two designs defined the class: the Pogo 40 and the Jumbo 40. But the success and longevity of the Class40 is due to its highly constrictive box rule, drafted by a group that includes wise French sailor and journalist Patrice Carpentier, which remains robust 18 years on.

The box rule’s basic parameters are a maximum length overall of 39 feet, 11 inches; max beam of 14 feet, 9 inches; draft of 9 feet, 10 inches; average freeboard of 3 feet, 6 inches; max mast height of 62 feet, 4 inches; max working sail area of 1,238 square feet; minimum displacement at 10,097 pounds; and max water ballast of 1,653 pounds per side. Most brutal are the materials limitations: Carbon fiber, aramid, honeycomb cores and pre-preg resin are forbidden from the construction of the hull, deck, interior structure and fittings; go down below on one and, joyously, thanks to the GRP construction, it is not coffin black.

Carbon fiber is permitted for the mast, boom and ­bowsprit, while standing rigging must be steel rod. Sails are limited to eight, and all but two and the heavy-weather jib must be polyester and nylon. A single fixed keel and as many as two rudders are permitted, but daggerboards and foils are banned, as are canting, rotating masts, mast jacks, and adjustable or removable forestays. However, complex kick-up rudders are permitted. (Although their effectiveness to kick up in a collision is allegedly dubious.) Over the years, displacement and average freeboard have slightly reduced, but the biggest rule amendment has limited “how scow” Class40 hull shapes can be. While the latest foiling Protos in the Classe Mini (the “flying bathtubs”) are fully flat-bowed, Class40 has two max beam limits just short of the bow to prevent this. Naturally, costs have risen, but the rule has successfully limited them; today, a top Class40 costs 700,000 to 800,000 euros.

Those sailing the Class40s in the early days were a mix of pros and amateurs. Today professionals on sponsored boats are the majority. As for aspirant French pro sailors, the Class40 has become a significant stepping stone between from the Classe Mini and Figaro circuits to the IMOCA.

As skipper of Groupe SNEF , leading Mini and Figaro skipper Xavier Macaire says: “The transatlantic races like this [Route du Rhum] are very interesting to us, and the boat is not very expensive. The Class40 is easy to maintain and prepare, and is not a complicated boat like an IMOCA where you need 12 guys. With this, you need two or three, not full time. It is an easy, fast boat.”

With more top pros like Macaire joining, 30 new Class40s have been launched in the last four-year cycle. The most recent Route du Rhum podium, for example, comprised two-time Solitaire du Figaro winner Yoann Richomme ( Paprec Arkea ) and Mini Transat winners Corentin Douguet ( Queguiner-Innoveo ) and Ambrogio Beccaria ( Allagrande Pirelli ) of Italy.

Of the French classes, the Class40 and the Mini remain the most cosmopolitan, with entries from other European countries, notably Italy at present, while the United States, Australia and South Africa were also represented in the Route du Rhum. Far from being put off by the pro element, Americans Alex Mehran and Greg Leonard were thrilled to be on the same starting line. “It is such a privilege to race against some of the top offshore sailors in the world,” says Leonard, who hails from Florida. “It is like playing football against a first team in the NFL—it is that level of quality. There are not that many sports you can do that in.”

Both American skippers came to the Route du Rhum from similar paths. With his Mach 40.3 Kite , Leonard is a professional economist originally from Texas. He campaigned a J/120 for many years with his remarkable son Hannes, who raced his first doublehanded overnighter with his father at age 13. Now 18 and with thousands of race miles under his belt, both in the US and Europe, he is a Class40 expert. For his father, the Route du Rhum was his first singlehanded race.

Over the years, several top shorthanded sailors, notably British Vendée Globe skippers Mike Golding and Miranda Merron, have raced with him, also coaching him. He is very enthusiastic about the Class40: “They are beautiful boats, such fun to sail. When we delivered her to St. Malo, we had 28 to 40 knots just aft of the beam, and we just hung in the low 20s boatspeed, and it was finger-light steering.”

Mehran skippers Polka Dot , which has the perfect pedigree, being Yoann Richomme’s 2018 Route du Rhum winner—a Lift V1 design. Growing up as part of the St. Francis YC Laser squad and subsequently a Brown collegiate sailor, he met Welsh Class40 designer Merfyn Owen in 2009 and raced one of his designs. Remarkably, he won his first major singlehanded race, the 2009 Bermuda 1-2. He subsequently graduated to an Owen Clarke-designed Open 50, in which he set a record in 2012’s singlehanded Transpac. He then went off, had four kids, and developed his commercial real estate business before getting the itch once more last year. He competed ­doublehanded with Owen in the 2021 Transat Jacques Vabre on an old Class40, but as Mehran puts it, “We needed to get ­something scow.”

He too has been receiving coaching from Merron and Golding, among others. According to Mehran, one of the most difficult things to explain to those back home is less the offshore-racing fever that afflicts French fans, but that their skippers are not multimillionaires. Instead, they come from a wide age group and all have commercial backing to either buy a secondhand boat or—if they are higher-­profile, more accomplished or just plain lucky—build a new one. So, returning to the Route du Rhum podium, Paprec’s business is waste disposal (admittedly, its owner races his own Wally 107), Arkea is banking and insurance, Queguiner is building materials, Innoveo is an app-­development platform, and Pirelli makes tires (its CEO has a Wally 145).

Over the last two decades, the Class40s themselves have evolved, despite Draconian design limitations. What started as cruiser-racers with fitted-out interiors became racer-cruisers and are now refined pure racers. They may not be black inside, but the build quality of the latest-generation designs is of the highest ­standard, and it seems no longer possible to buy a cruiser-racer.

A delight of the Class40 is that no one designer is dominant; eight different designs make up the 30 boats built over the last four years. Pogo Structures, last of the original builders, is on its fourth version of its Pogo 40, the S4, designed by Emirates Team New Zealand’s naval architect, Guillaume Verdier (who also designed Structures’ scow-bowed flying Proto Mini).

The man who developed the first blunt-fronted scow Mini, David Raison, produced the Max40, built by JPS in La Trinité-sur-Mer. Also built by JPS are Sam Manuard designs—the Mach 40.4, such as the 2021 Transat Jacques Vabre winner Redman , skippered by Antoine Carpentier (nephew of the original rule’s writer), and now its evolution, the Mach 40.5, of which two competed in the Route du Rhum.

In 2020, VPLP made its first foray into the class with the Clak 40, built by Multiplast, of which four raced in the Route du Rhum, the top finisher being Martin le Pape’s Fondation Stargardt. Etienne Bertrand, another successful Mini designer, had two Cape Racing Scow 40s in the race, while Allagrande Pirelli , believed to be the most expensive of the latest crop and campaigned by last year’s Mini Transat winner, Ambrogio Beccaria, is an all-Italian affair designed by Gianluca Guelfi and built by Sangiorgio Marine Shipyard in Genoa.

However, after the recent Route du Rhum, ­nosing in front in the design race is Marc Lombard with his Lift V2s, of which seven were racing, including Yoann Richomme’s winner, Paprec Arkea . Lombard is one of the longest continuous players in the Class40, and has worked with Tunisian manufacturer Akilaria on its RC1, RC2 and RC3 models since 2006, of which 38 were built. His latest designs have been the Lift, introduced in 2016; Veedol-AIC , one example, took Richomme to his first Route du Rhum victory. The Lifts were custom-built with a hull and deck made by Gepeto in Lorient, but finished off by the V1D2 yard in Caen, and were more precisely engineered and built than the Akilarias. They were superseded this cycle by the Lift V2, the most popular of the new Class40s, with seven competing.

For Richomme, the Route du Rhum was a small distraction from having a new IMOCA built. He entered the Route du Rhum to defend his title and stay race-fit. If the first Lift was an early scow, the present one is at the limit, to the extent that it has a bump in the hull 2 meters aft from the bow at the limit of where the Class40 rule restricts the max beam to prevent such extreme scowness.

The scow bow provides more righting moment, but it also does interesting things to the boat’s hydrodynamics. “With a pointy bow, the keel is more angled and creates more drag,” explains Richomme, who is also a trained naval architect. “When a scow heels, the hull is almost parallel to the keel, so sometimes when we go over the waves, we can feel the keel shudder when it is producing lift. The chine is low and therefore very powerful, and when we heel, it makes for a very long waterline length. Also, we have very little rocker, whereas other [new] boats have a lot, which creates a lot of drag so they don’t accelerate so well when they heel.”

The Lift V2 “is a weapon reaching,” Richomme says. “We can hold the gennaker higher than we used to. Last time, I didn’t even take one. But with the power going up, so have the loads, and we are having problems with the hardware. I have broken two winches already.”

A downside of the big bow and straight chine is downwind, where the technique seems to be preventing the bow from immersing. Paprec Arkea is typically trimmed far aft, including the stack and the positioning of the 1,653 pounds of water ballast (most new boats have three tanks each side), while its engine is 19 inches farther aft, and the mast and keel 11 inches farther aft than they were on his previous boat. They are 77 pounds below the minimum weight, which Richomme admits may be too extreme—during training they broke a bulkhead.

Otherwise, their increased cockpit protection is most noticeable on all the new designs (although not to IMOCA degrees), while most have a central pit area with halyards fed aft from the mast down a tunnel running through the cabin. On Paprec Arkea , a pit winch is mounted just off the cockpit sole. With the main sheet and traveler lead there as well, Richomme can trim from inside the cabin.

Most extraordinary about the scows is how fast they are. Anglo-Frenchman Luke Berry, skipper of Lamotte-Module Création , graduated from a Manuard Mach 40.3 to a 40.5 this year and says: “It is a massive improvement both in speed and comfort. Reaching and downwind, we are 2 knots faster, which is extraordinary.”

The top speeds he has seen are 27 to 28 knots. “Most incredible are the average speeds—higher than 20.”

This effectively turns yacht-design theory on its head, with ­waterline length and hull speed having less effect upon defining the speed of a boat that spends so much time planing. On the Mach 40.5, the waterline is just 32 feet, with a length overall of 39 feet. Compared to the Lift V2, it has more rocker, supposedly making it better able to deal with waves.

Nowhere is the speed of the latest Class40s more apparent than where they finished in the Route du Rhum in comparison to the IMOCA fleet. Paprec Arkea arrived in Guadeloupe ahead of 13 IMOCAs, or one-third of the way up the IMOCA fleet. Richomme says he used to sail on a Lombard-designed IMOCA 20 years ago, when they would make 10.5 knots upwind. “On a reach, I reckon we are faster than them now. We can do 20 to 22 knots average speed.”

Ugly seems to be quick, but when it comes to the Class40, beauty is in the eye of the beholder of the trophy.

Class 40 Sailing: First Impressions

• June 2nd, 2016
• Sailing Yacht

Now that some 4 weeks passed by since I´ve had my fist real offshore sailing experience with a Class 40 sailing yacht and with having gained some distance to that trip I am trying to sum up my experiences and bundle testimonies of my fellow crew mates to have a thorough review of what it is like to sail a Pogo 40. You may read the cruise report of the first leg here  and of the second leg under Gennaker here  .

First of all: Looking at the boat is an experience by itself. Being accustomed to the view onto classic yachts, seeing this compact, flat hull with its extra-wide stern is amazing. This hull seemingly promises to go fast by its looks alone. My heartbeat went faster upon arrival at the mooring and it was the same with the other crew members. Let´s board the ship and have a look around.

Rigging and Cockpit Layout of a Class 40

A Class 40 is made for single handed and double handing racing. That means first of all that all ropes and lines must be guided in a way that they could be worked upon from the cockpit. Which is done beautifully in the Pogo 40: All halyards run down within the massive carbon mast or over the cabin roof and through jammers and can thus easily be unlocked, brought on to the winch and worked with. Only for hoisting and reefing of the mainsail somebody has to proceed midship to the mast.

When sailing single or double handed – above all in race situations – maneuvers have to be carried out with speed. To assure this, everything has to be within reach of one person: And it is indeed! There is a sheet winch on either side of the cockpit, well within reach with the one mainsheet winch on the center-housing for the life raft. This winch can operate both sheets of jib and Genoa as well as the backstays which also run through spinlocks.

Traveller sheets end in spinlocks right vis-à-vis the mainsheet winch. So, in theory a lone sailor could handle all the running rigging alone. Which of course is proven by a dozen of single hand sailors on Class 40 yachts all over the oceans. Although the cockpit is with its 4.50 meters extremely wide, ways from winch to winch and to the tiller helms are very short. The timeframe from changing conditions to a reaction can thus be made very short.

Of course, our Pogo 40 was equipped with Lazy Jacks to have the ritual of taking down the main sail made as easy as possible, though I can state by my own experience that both hoisting these 70 square meters of canvas and taking them down properly was extremely hard work: I can barely imagine doing this all alone. Thank god electric winches are invented. I felt at home in our Pogo´s cockpit and after a few hours manning the different stations was a no brainer. Again: Being responsible for the whole ship alone should be trained very thoroughly. A Class 40 is far away from being a no frills boat control wise.

Class 40 Sailing: Fast Planing like a Rocket

That was something I was looking forward to the most when booking a cruise on this boat. After having done the interview with Sven, co-owner of SY KNUBBEL, a Pogo 12.50 (which can be read here ) I was impatiently waiting for that sensation when the hull does overcome the boundaries of the wave system and sails faster than her theoretical maximum hull speed. So, all hands on deck, hoist all sails-ho! And tell me now what´s this planing like?

“Planing is when this constant gurgling and bubbling at the stern suddenly stops and is substituted by a smooth Swoosh….- like sound”, tells Sven when I was asking him. Sitting at the helm of POGO 1 beating upwind with 11 to 12 knots I am shouting to the skipper: “Capt´n, at which speed will she start planing?” “We already are – it needs 8 knots”. And yes, looking aft in our wake I notice a white trail indicating the gliding of our hull. It´s just an awesome feeling!

Maintaining control over the ship´s bearing is easy: The Pogo 40 is equipped with twin rudders in such an arrangement that even when heeled extremely the lee-rudder will have full steering capabilities. There was never too much pressure on the rudders though we didn´t have had to cope with too severe gales or swell conditions. It felt quite easy to trim her course by giving rudder – she reacts very vivid and instantly to even smallest corrections. Steering whilst planing? No difference to the classic way of sailing.

Speaking of heeling: The Pogo 40 needs heeling. This process assures the exposure of a smallest possible wetted surface under water thus reducing resistance. She sails very stable even when heeled extremely to up to 40 degrees and I never had the impression of being unsafe. Roaming about on deck when heeled is tricky: It´s wet and slippery, there are ropes virtually everywhere and – when sailing with a crew of five – even a 4.50 meters wide cockpit can easily become cramped.

A truly unique experience was sailing under Gennaker (which can be read in detail here ). The Class 40 is trimmed to go downwind – and she will go as fast as hell! Fastest speed on our POGO 1 in light conditions has been 14 knots, our skipper told us of occasionally exceeding speeds of 20 knots easily. Again: This is a racing machine and riding this stallion must be done only by experienced skippers and crews. She´s definitely not a boat for the rookie.

The Beauty of Sailing a Class 40

Nevertheless, counting myself to the rookie side and looking at how my fellow crew mates managed their jobs on board – all of them with far more experience in sailing than me – with a good skipper sailing on a Class 40 is both exciting, full of adventure and thrilling on the one hand and filled with beauty and grace on the other. Seeing the Class 40 under all canvas, accelerating to full speed and starting to plane filles me with pure joy.

It is barely imaginable that any sailing vessel can sail faster than these kind of boats. I was puzzled when we were overtaking another sailing yacht going at full speed with engine in a matter of minutes, doing our 50 miles in less than 6 hours with light winds. Although it´s a frightening idea but I´d love to be sailing with a Pogo 40 when things get a bit rougher. Well … there are some cruises offered on the Pogo 40 in September. This do get rough in September … This yacht let endorphins flow to the liters, people do have a constant grin on their faces for it is extremely satisfying to sail on a Class 40. Going fast is satisfying: Who wouldn´t trade his VW Golf for a Porsche? I felt constrained to compare the beauty of these boats to the grace of the old square rigged Clipper ships, which might be a sacrilege, but thinking of it there are so much similarities to these fastest sailing vessels of forgotten times.

“She sails wet.”, said skipper Thomas when conducting the safety briefing. There was some water coming down the companionway indeed, but I read reviews of real tough regattas and saw pictures of saloons full of water, soaked cushion and no dry place left whatsoever. As well a frightening prospect, but hell, this must be an awesome experience!

Reviewing a Class 40 Interior

Down below a Class 40 like the Pogo 40 is a true miracle regarding space. She is a 40 ft. boat – I personally find 40 feet with more than 12.50 meters huge compared to my 33 ft. King´s Cruiser – but due to her extreme width of 4.50 meters internal space is just huge! Even with 5 adults leaving their berths, brushing teeth, searching for clothes and having a cup of coffee the saloon didn´t felt cramped at all.

The main saloon is dominated by the large navigation station right on the keel in the middle of the cabin. A seat, a rugged laptop, radio and plotter – even by poking one´s head down the companionway all essential data could be grabbed at once. Down the cabin in the middle is a big fridge and the large folding table which makes dining even with a big crew easy.

Due to the fact that this is a high performance yacht you shouldn´t expect panels or veneers: Even the massive structural stringers of the underbody structure is clearly visible. Watch your step! There´s an L-settee to the port side, a long settee on the starboard side right after the galley which features a two-fire stove, a large sink and working table.

The Pogo 40 features two aft cabins of which the starboard cabin is large enough for two persons, the port cabin has a berth too is also filled with machinery such as heating, vents and pumps and the main power control. Here a more than bare head is to be found: One can seal off when doing his business by having a curtain applied, but again: No doors, no real visual protection and no sound protection at all. It´s a race – not a cruise …

Next to these three possible berths there is more on the port side settees, two persons, another one on the starboard side and – whilst in port – the fore cabin could offer two additional berths. In the end, a crew of 8 persons could find a place to rest while on board but again, that´s just in theory.

When we have been underway with five people – four crew and one skipper – we´ve had two of us in the forepeak, me and another member in the aft cabin, skipper and the last crew member in the saloon berths. Though I didn´t slept on any of the other bunks, I guess I have been lucky indeed having won a berth in the comfortable aft cabin.

To sum it up: The interior won´t appeal to everyone since the isn´t any. Wooden surfaces are limited to galley and folding table, cushion is water proof and so not very cozy (the color being grey does add nothing to create a “ship-like” atmosphere as well) and there is bare GRP everywhere you look. She´s a pure racer. Oh, is she?

Cruising with a Class 40?

There are more owner cruising with their boats than serious racers. You can do cruising with these boats: They have everything needed. This ship is large enough to have provisions and fuel for Blue Water passages, more than enough space and – above all – it will bring you faster to the destinations of your dreams or – being fast above all – allows to stay longer because of reduced sailing time. I guess, a Pogo-concept of fast sailing does correlate with a French sailing philosophy (which I tried to look into here  by interviewing Charly Fernbach of Pogo structures and naval designer-legend Marc Lombard).

If one can adapt to this bare and uncomplicated style of sailing by actively abstaining from luxury I would say yeah, cruising with a Class 40 can be done and should be done! Why wasting precious time on lame old fashioned cruisers? Why not prowl the oceans with speed, arrive early and spend more time? Well, I guess it´s because these days a classy wooden Hallberg-Rassy interior has its fans still – and besides, controlling a yacht like the Pogo 40, going wet and fast with extreme heeling is prospect of asking too much of the ordinary family skipper.

Looking at the sparse interior fitting – even when thinking of replacing the faux water proof leather of the cushion by a friendlier, fresher color, it´s still hard to envision myself and my family going on a long cruise (even a short one) in this boat. Well, envisioning myself I can, but the family … Nevertheless, there are reports of some families doing exactly this.

And the more I think about it – given that I can build up more and more competence and sailing abilities over time – this idea becomes attractive and tempting to dream of ever more. I just love this no-frills-approach to sailing (apart from the not-so-no-frills demand of the boat to be controlled with aplomb), this clean, white, bare surfaces. No wooden panels to care about, easy to maintain and clean, no doors, no portholes – no frills.

I fell in love …

And with all these no frills-commodities, there comes so much joy, so much adventure, so much fun. So much demanding in this boat and – which is most attractive I would say – so much gain in reachable distance! Going faster than 10 knots at virtually any time increases the range of activities extremely: Going faster could mean to reach more distant places or reach more places in the same time. Fascinating. And, sadly enough, unreachable for me (and totally impractical as well). But there´s a solution: Simply by booking another cruise on these fantastic sailing machines.

An alternative for owners who seriously consider to get a Class 40 could be the smaller yet comparable Class 9.50 racer of which some interesting boats are on the market, or – very interesting indeed – a Beneteau Figaro II. A sailing yacht legend of which I am going to publish a couple or articles in the near future.

Bottom line: Class 40 sailing has opened my eyes and thinking back to the wonderful 110 miles aboard POGO 1 still thrills me.

Class 40 “Icarus Racing” 40' / 12.19m

The first Class 40 to be designed and built in the United States. Currently being campaigned by Jeffrey MacFarlane. http://jefferymacfarlane.com/

Yacht Specifications

“ICARUS RACING” – the first U.S. built Class-40

Build of the boat is by Ted Brown and Stewart Wiley of Al Fresco Composites, Portsmouth, RI.

To begin the design process we decided to test a series of hulls in a weather matrix for the race as well as a long-race performance predicition tool developed in-house by RMD. Class 40 is a ‘box rule,’ so we investigated one shape overtly maximized to the box. The other extreme was considerably narrower than the maximum, with a single rudder, lighter hull and a higher ballast-ratio, both to the minimum displacement. A third boat tested was between these extremes. For these three exploratory types, we used a ‘parent/child’ annex to our Velocity Prediction Program (VPP). This allows the boat to choose the location and amount of ballast (including ballast to leeward or empty) to give the boat its best performance in every wind strength and direction. Of course it doesn’t take into account sea conditions, exhaustion, broken gear and the indefinable issue of seakindliness. If it did, we could leave it all to the machines!

An intuition that a subtle step further was needed, led to the final hull choice. It was faster in the weather matrix and RMD’s own RTW test by a greater margin than all the others. We were on our way and sent the surface files to Goetz Custom for computer cutting. Design partner, Ross Weene has worked wonders (and long hours) to complete this program efficiently and accurately.

Spars are by Halls Spars of Bristol, RI.  Sails are North 3Di. Steve Koopman, Dirk Kramers’ partner in SDK Structures has worked with Ross to engineer advanced light, durable hull and appendage structures with materials from Rich O’Meara’s ROM Composites of Newport.

This is not only an all-out US entry into Class 40 and ocean racing arena, but an all-Rhode Island entry too.

Class40 was born as a result of the distillation of excellent yet simple ideas. Designers, sailors and boat builders had been working on the idea of a dedicated offshore race boat for some years prior to the creation of the Class in 2004. A boat somewhere in between a Series Mini and an ocean-going 60 footer. A true race boat of course, but more than that… a boat sufficiently seaworthy to safely sail across the Atlantic. The Class40 was already well on its way… For several years, ideas had been based around a 40 footer, but had not yet taken form. In 2004, at the request of many people in the marine industry, skipper-journalist Patrice Carpentier took the initiative to draft the Rules for Class40. He brought together the skipper Michel Mirabel, Christian Bouroullec of the Structures Boatyard, and Pascal Jamet, CEO of Volvo and passionate about sailing. Between them, they created the "Class40" Association. Creative influences and moderating influences in the same boat... At the time, on the one hand there were boatyards with existing 40 footers. Of particular note was Structures' Pogo 8.50 which had just won the Transquadra, and the Jumbo 40 from the yard of the same name. These boat builders knew that there was a demand, and a market for this kind of boat. They wanted to find a framework and rules for this 40 footer aimed at enlightened and "wise" sailors. On the other hand, there was a group of designers and racers from the Classe Mini, full of talent and ideas, and fans of sailing at speed and surfing. "Patrice Carpentier managed to get these two groups, both of which were brimming with what appeared to be incompatible ideas, but which were in fact totally complementary, to work together" , explained Pascal Jamet. "There were creative influences and moderating influences... " Drawings of existing 40 footers, and boats which had yet to be built were put on the table. The brief contained three points: design a simple, reliable and fast boat. "We set ourselves the goal of making the rules fit onto two pages!" recalled Patrice Carpentier. "It took us about a year to define the rules, but it was fascinating! It isn't easy to get numerous designers around the table at the same time! They are all stubborn but utterly brilliant individuals!" recounted Pascal Jamet. 2005 Paris Boat Show: Class40 unveiled At the Paris Boat Show in 2005, the Class40 Rules and the broad outlines of this new offshore class were officially unveiled, and a race programme in which the 2006 Route du Rhum was to be the highlight. The conference room was packed. The audience was captivated: Class40 had its first success. The success of the Class was rapidly confirmed in the following months. The Pogo 40, the Jumbo 40 and then the Akilaria came out of their respective yards. Many designers took to the drawing board. The first prototypes appeared... "It happened very quickly! We were astounded by the enthusiasm generated by this Class!" recalled Pascal Jamet. And in fact, ten months later (a mere 10 months...), in October 2006, the Class already had 54 members, and 25 Class40s lined up for the start of the Route du Rhum! These 40 footers made up a third of the fleet in this mythical transatlantic race... Since then, Class40s systematically make up the largest fleet in the offshore races they take part in. In 2007, the Class40 Association had 129 members, and 30 of them were on the start line of the Transat Jacques Vabre. Since then, the Class has settled at 120 to 130 members per year, and a fleet of 40 or so boats which compete regularly. Conviviality is the catalyst In terms of quantity, the Class had made it. In terms of "quality", the brief was answered to perfection. "We wanted to create a Class for enlightened amateurs, and a race circuit accessible to all. A Class which enables all good sailors to fulfil their dream of offshore racing - easily, for pleasure, and without bankrupting themselves, or spending months in the yard on a complicated prototype," explained Michel Mirabel. It was spot on. Heads of companies and professionals who have kept a toe dipped in the water and the wind in their hair, make up the bulk of Class40 membership. Young semi-professional sailors have joined the fray. The end result is a successful mix of sailors. Everyone is delighted with their new-found freedom to do be able to do what they want: take part in offshore races. Friendships have formed from the earliest Class40 races. Memories are etched for good. This is the glue of Class40. Diversity: a long-term attribute Since its creation, Class40 has found its place in the world of offshore racing. It quickly expanded internationally: South Africa, Germany, England, Belgium, Bulgaria, Spain, USA, Holland, Italy, Norway... Today, Class40 is made up of sailors from 22 different countries. Patrice Carpentier sees this is a strength: "The mix of different types of people and the internationalisation of the Class are very good attributes. What makes Class40 so attractive is its diversity, and that makes me optimistic for the future." This diversity can also be seen in the lines of the Class40 boats themselves. Designers have had a ball finding ways to optimise the Class Rules. Inevitably, boats have steadily become more powerful. "Class40 is just fine as it is! We got the basics right, because not only have we been able to design very different boats within the same framework... but there are still lots of avenues for designers to explore," enthused François Lucas, designer, and one of the founding members of the Class. However, Michel Mirabel believes that it is crucial to remain faithful to the founding principles of Class40: "Where the rules are concerned, we need to systematically go for the solution which costs the least. It is the only way to prevent an arms race. We must stick firmly to this principle." A Class to watch... With undeniably good beginnings and now well-installed in the world of offshore racing, Class40 has won its first bet. For the future, the Class must find the right balance between performance and accessibility; between "pro" budget, and simply budget; between true offshore races and "grand prix" events open to all... Class40 is on course. It must make the right tactical decisions: those which enable sailors to fulfil their dreams.  Author : Catherine Ecarlat

Though now an old and dated design, the Cal 40 was a hot boat when new, and she carries that legacy.

Thunderbird, a Cal 40 owned by IBM president T. Vincent Learson, took first in fleet over 167 boats in the 1966 Bermuda Race. Because this was the first computer-scored Bermuda Race, Learson got a lot of gaff about the IBM computer that had declared him the winner—and about beating out his boss. Thomas J. Watson, IBM’s chairman of the board, sailed his 58′ cutter, Palawan, second across the line, but ended with second in class, 24th in fleet, on corrected time.

In fact, the computer scoring system was not especially kind to Learson. Both he and Watson would have fared considerably better under the old system that calculated scores from the NAYRU time allowance tables. Thunderbird’s victory was a legitimate win, another in a stunning series by Cal 40s that was establishing the boat as a revolutionary design. The first Cal 40 was built for George Griffith in 1963. That winter, hull #2, Conquistador, took overall honors in the 1964 Southern Ocean Racing Circuit (SORC). The Transpac races of 1965, ’66, and ’67 all went to Cal 40s. Ted Turner’s Cal 40, Vamp X, took first place in the 1966 SORC. In the ’66 Bermuda Race, five of Thunderbird’s sisterships finished with her in the top 20 in fleet, taking five of the first 15, four of the first nine places. And so on. In their first few years on the water, Cal 40s chalked up an astonishing record.

The 40 was the fifth in a line of Cal designs that C. William Lapworth did for Jensen Marine of Costa Mesa, California. Lapworth had already designed a series of moderately successful racing boats, the L classes, including an L-24, L-36, L-40 and L-50, when he teamed up with Jack Jensen. The Cal designs were built on concepts he had tried in his Lclass boats. The first Cal was the 24, Jensen’s first boat, launched in 1959. The Lapworth-Jensen team then produced a 20, 30, and 28 before getting to the Cal 40, which proved to be a successful distillation of Lapworth’s thinking up to that time.

Aspects of the boat that departed from the conventional wisdom were her light displacement, long waterline, flat bilges to encourage surfing, fin keel and spade rudder. The masthead rig is stayed by shrouds secured to chainplates set inboard of the toerail, a then unusual innovation that allows a reduced sheeting angle. The success of the design helped legitimize fiberglass as a hull material, establish Jensen Marine as a significant builder of fiberglass boats, and propel Lapworth to the forefront of yacht design.

Three decades have passed since Lapworth drew the Cal 40. In that time, using computers to score races has become commonplace—boat measurers and designers would be paralyzed without them. The CCA Rule, the NAYRU tables and the Portsmouth Yardstick have been replaced by IMS, IOR, and PHRF, with the effects of their parameters expressed in the shape, size and weight of new boats. New building materials and techniques have changed the meaning of terms such as “light displacement,” “long waterline,” “fin keel,” and “fast sailboat.” Today the Cal 40 is a dated design, having been surpassed in her revolutionary features by her descendents. She remains among the esteemed elite of racing yachts, but she is not especially light, long on the waterline, or fast compared to current designs.

The Cal’s builder was transformed by time, as well. Jensen Marine was bought by Bangor Punta Marine, and the Cal production line was moved to Florida about the time that the Cal 40 went out of production in 1972. For the next decade, the company’s name and address shifted between combinations of Cal, Bangor Punta and Jensen in California, New Jersey and finally Massachusetts, where it joined O’Day under Bangor Punta’s umbrella in the early 1980s. After 1984 the company was called Lear Siegler Marine, Starcraft Sailboat Products, and finally emerged as Cal, a Division of the O’Day Corporation, in Fall River, Mass. Cal and O’Day ceased production in April, 1989.

Construction The construction of the Cal 40 is typical of Jensen Marine boats of the 1960s. The hull is solid hand laid fiberglass with wooden bulkheads and interior structures. Strips of fiberglass cloth and resin secure the wooden structures to the hull, but this tabbing is rather lightweight and has been reinforced in some Cal 40s where it has failed. If it has not been reinforced, it probably needs it.

Because saving weight was a priority in building the Cal 40, the reinforcement provided by the bulkheads and furniture is critical to hull stiffness. Failure of the bonding can be a significant structural concern.

The hull-to-deck joint is an inward-turning hull flange, upon which the deck molding is bonded, then through-bolted and capped with a throughbolted teak toerail. This is a strong type of joint, but there is some complaint of minor leaking along it in a few boats. The leaks are most likely one result of the relatively light construction of the hull skin, which has a tendency to “oilcan” in heavy weather, creating stresses at the joint.

The deck, also a solid fiberglass layup, has reinforcement designed into it during layup, so no interior metal backing plates are provided under winches, cleats, and other hardware. PS generally recommends backing plates behind high-stress hardware as a matter of course. We found little indication of trouble with leaking or working of most of the fittings, but one owner said that his lifeline stanchion bases had to be reinforced. This would be an area to inspect carefully.

Colors and non-skid surfaces are molded in, but due to the age of any Cal 40, the finish will look tired unless it has been renewed. A good Awlgrip job will do it wonders, and is probably warranted for this boat unless it is in general disrepair.

The deck and cockpit of the Cal 40 we inspected have numerous cracks in the gelcoat in corners and other stress areas. Check these areas closely—they are unsightly, but in most cases are not a structural concern.

Ballast is an internal lead casting dropped into the keel before the insides were assembled. If there is evidence that the boat has suffered a hard grounding, invesitgate the ballast cavity to see that it was properly repaired. It should not have a hollow sound when rapped, and there should be no cracks, weeping, or other evidence of moisture inside. Due to the construction sequence, major repairs could be awkward.

Wiring was also installed prior to the interior, which makes it quite inaccessible in some areas. What may be of more concern is that it is low enough in the boat to get wet if the last watch forgot to pump the bilges and the boat heels over to her work. That’s what happened to one owner, who lost all the electricity on the boat when approaching Nova Scotia’s Bras d’Or Lakes after an all night sail. Fortunately, dawn arrived in time to avert a navigation problem. They anchored in the harbor and found that the electrical system worked fine, once it got dry again. Before the next season rolled around, the boat’s entire electrical system had been replaced in elevated, accessible locations. The implication is that you should look carefully at the wiring in a Cal 40 before you make any decisions. If it has been replaced, try to learn who did the work and how well qualified he/she was for the job. If it has not, you may have to work the cost of rewiring into your acquisition expenses. We would suspect the worst until proven otherwise.

You might expect wheel steering on a boat this size, but the stock Cal 40 came with a big tiller. The boat is well enough balanced to be controlled with a tiller, and many helmsmen prefer it to a wheel, which masks feedback from the rudder and makes sensitive steering more difficult.

The cockpit is roomy, but properly designed for offshore work with relatively low volume, a bridgedeck and small companionway. The tiller sweeps the cockpit midsection, allowing the helmsman to sit fairly far forward, a help to visibility.

Winch islands are located aft of the helmsman, where there is room for the crew, but it also makes the sheets accessible to the helmsman for shorthanded sailing. The teak cockpit coaming has cutouts giving access to handy storage bins.

The aluminum mast is stepped through the deck to a fitting that meets it at the level of the cabin sole. The shroud chainplates are secured to a transverse bulkhead at the mast station, and then tied into an aluminum weldment in the bilges. This weldment also supports the mast step. While chainplates have been an area of concern in some designs, because they can work under the large loads they carry, our indications from Cal 40 owners are that the chainplate/shroud/mast step attachments have served well.

Sailing Performance The Cal 40 is in her element in heavy air, especially off the wind. Her long waterline and flat bilges help her get up and go on reaches and runs, surfing in heavy air. On the wind, the flat hull forward pounds in waves and chop, which slows the boat somewhat and is irritating. Owners agree that she sails best with the rail in the water. She is not dry on the wind, so a dodger is a welcome feature.

The masthead sailplan allows relatively easy reduction of headsails to suit heavier conditions, and Cal 40 owners extol the survivability of their boats. “Simple rig, nothing breaks, strong, easy to use,” is a typical comment. Despite her stellar racing record, the Cal 40 is only ordinary in performance by today’s standards. She carries a PHRF rating between 108 and 120 seconds per mile, depending on the region. That’s about the same as a C&C 38 or an Ericson 36, both IOR designs of the late 70s. Compared to a mid-1970s design such as the Swan 38, the Cal 40 is a bit slower on the wind and in light air, a bit faster off the wind and in heavier going, about equal in speed overall. It’s not surprising that these boats perform alike if you look at the length of their waterlines and their displacements.

In comparing the Cal 40 to boats of her own vintage one sees what all the fuss was about. The Columbia 40, for example, is a 1965 Charles Morgan design, an “all-out racer” with a 27′ waterline, displacement of 20,200 pounds, and a PHRF rating of about 170. Or look at the Hinckley 41: 29′ on the water, 18,500 pounds, PHRF about 160.

The Cal 40’s waterline is almost 31′, but she displaces one or two tons less than the Columbia or the Hinckley, and rates nearly one minute per mile faster under PHRF. In that context, she is indeed a fast, light displacement boat with a long waterline. Just look at her “fin keel” and you can see the progression. Compared to a full keel with attached rudder, it is small. Compared to a modern fin keel, it hardly seems small enough to qualify for the name. If Cal 40s win races today, it’s because they are well sailed, not because the boat is the fast machine on the race course.

Interior In the 60s, “accommodations” tended to imply the number of berths in a sailboat, and the more the better. It also included the notion of a basic galley with sink, stove, icebox, and a table of sorts, plus a head with toilet and sink. Space age electronics had not arrived in the galley or the nav station, nor had space arrived in the concept of the main saloon.

Inside, as elsewhere, the Cal 40 is well designed and functional, but she speaks of her own era. The layout is very traditional, with a V-berth forward, separated from the main cabin by a head and hanging locker. Pilot berths and extension settees port and starboard provide sleeping for four. The dropleaf table seats four, six if you squeeze. Next aft is the galley to port and a nav station to starboard, consisting of a chart table over the voluminous icebox. The galley has a usable sink next to the well for a gimbaled stove with oven.

Flanking the companionway steps are the entrances to the quarterberths, known affectionately as “torpedo tubes,” which gives you an impression of their dimensions. They extend from the main cabin through to the lazarette, which allows good circulation of air. In fact, on a return trip from Bermuda, one seasick sailor found great solace between tricks at the helm by climbing into one of the cocoon-like torpedo tubes, where he was washed with a fresh breeze from  the dorade vent on the lazarette cover. The fact that the quarterberths flank the engine compartment  doesn’t matter as long as you are under sail, but it’s a different story when under power.

So you have sleeping accommodations for eight, which is too many people on a 40-footer, except perhaps when racing. The extension transom berths, however, do not lend themselves to use under way. The interior, not spacious by modern standards, fills up fast with extra bodies aboard. Owners tend to convert some of the berths to storage space. The pilot berths are especially tempting for that use, but since they are also the most comfortable berths on the boat, the quarterberths are often sacrificed for storage.

One of the best features about the Cal 40’s interior is the dining table. Set slightly to port, it is supported by a sturdy sole-to-overhead stainless steel post at each end with a 4′ 4″ gimbaled mahogany tray between them above the table. The posts make excellent handholds, and the gimbaled tray can serve for everything from salt and pepper holder to bookshelf to diaper-changing table. The table has a drop leaf to port and to starboard, so it can be set up for use from the port settee without blocking fore-and-aft passage through the boat.

Engine A variety of powerplants will be found in Cal 40s. Some early hulls were equipped with Atomic 4 gasoline engines. Later hulls got Graymarine 4-112 gasoline or Perkins 4-107 diesels. It’s likely that the original engine will need to be replaced if it has not already been done. Even the newest Cal 40s are rather old, and the early models have passed the quarter-century mark.

Boats in our files have Volvo MD2B, the Perkins, Pathfinder 50, Westerbeke 4-108, and Pisces 40 from Isuzu listed as replacements for the original engine.

The engine is located under the cockpit, between the torpedo tubes, which allow access to both sides, but are not especially convenient, particularly if the area has been turned into storage space. Better is the companionway ladder, which removes to expose the front of the engine. That can be an inconvenience, too, if the engine needs some attention while under way.

Used for the minimum requirements of a racing yacht, primarily getting in and out of port, you can probably make do with any of the engines. If the boat is to be used for cruising, with greater demands to be made on the engine, the Atomic 4 would likely be inadequate.

Generally the boat will do about six or seven knots under power, depending on the power plant and propeller. We suspect that many Cal 40s will have folding propellers, good for racing but not the best for powering, especially in reverse. The spade rudder set well aft confers good maneuverability under most conditons.

Conclusions The Cal 40, a hot racing boat when new, carries that legacy with her into maturity. Generally, the boats have been raced hard, some cruised hard as well.Owners have tended to be the type to add gear and modifications to keep the boat comfortable and competitive. The boats are likely to have a large inventory of much-used sails.

Because of her age and dated design, a Cal 40 may be available for much less money than a newer boat offering comparable quality and performance. Prices will vary according to the condition of the boat and gear, but will likely fall in the range of $40,000 to $50,000. If the boat has lots of add-ons in the galley and nav station, modern racing hardware, renewed standing rigging, new finish on the topsides, and the bottom is in good condition, it might fetch something higher. One performance extra to look for is a special (non-factory) fairing job on the keel and rudder that was available when the boats were young.

On the other hand, it should not be a surprise if there are areas that require attention, and you should calculate the cost of the work into the price you are willing to pay. Twenty or 25 years of hard sailing will take its toll. Significan’t expense could be incurred if the boat needs new wiring, an Awlgrip job on the topsides, extensive reinforcement of the interior furniture tabbing, a new engine, or new rigging. If racing is in your plans, new sails might be scheduled in as well.

This would be a good boat for a handy do-ityourselfer. Over the years, most of the boat’s problems have been solved more than once by other Cal 40 owners, many willing to share their wisdom. You would probably have a choice of solutions, and indications of which worked best.

Although there is not currently an active owners association, there persists a loose fellowship among present and former owners. If you buy a Cal 40, you will acquire a modest boat, with good pedigree and performance, and—should you desire them—a few new friends, as well.

THE CLASS40

What is a class40.

The Class40 is a monohull dedicated to offshore racing. This boat has existed since 2004 as an intermediate oceanic boat, between the Mini 650 (6.50m) and the 60-foot Imoca (18.24m).

A boat framed by a strict gauge: – Maximum length: 12.19 m. – Maximum width: 4.50 m. – Maximum draft: 3 m. – Maximum air draft: 19 m. – Maximum displacement (weight): 4,500 kg. – Maximum sail area: 115 m2. – Ballasts: 1,500 liters. – Fixed keel and mast (tilting keel and tilting mast prohibited). – Maximum removable bowsprit: 2 m. – Average freeboard: must be at least equal to 1.08 m. – Daggerboard and foils prohibited. – Several prohibited materials such as carbon and Kevlar.

Today more than 170 boats have left the sites with a panel of international architects and runners from all backgrounds of sailing, and even from other sport.

The Cult of the Cal 40

The classic 1960s ocean racing legend.

The  Cal 40  is a roughly 39-ft 4-in fiberglass production racing and cruising sailboat, of which about 155 were built in Costa Mesa, California, starting in 1963. The first mass-produced sailboat that was capable of sustained surfing on waves, the Cal 40 dominated ocean racing during the 1960s like no other design before or since. It’s the original longboard, a Southern California surfing machine that is capable of sustained 15-knot downwind speeds.

The Boat That Changed Everything

This breakthrough design ushered in dramatic changes in offshore racing, from the moment that Cal 40 #2,  Conquistador, won the 1964 Southern Ocean Racing Conference, the marquee big boat series at the time. “Wooden ships and iron men” had been replaced by fiberglass boats and kids, as Cal 40s, sometimes crewed by teams of teenagers, crushed the competition in the Bermuda Race, the Transpac and many others.

The Cal 40 was created as the combined work of three men. George Griffith, a successful racing sailor and member of the Los Angeles Yacht Club, reportedly drew the outline of a new kind of racing yacht hull on the back of a napkin, and showed it to his friend, naval architect C. William Lapworth. Griffith observed that sailing dinghies, like the International 14 class, were extremely maneuverable with their rudders hanging on their transoms, unlike the typical 40-footer of 1962, which was a full-keeled, heavy beast with the rudder swinging on the back of the keel.

Radical Ultralight Hull

Griffith’s sketch showed a flat-bottomed, radically ultralight hull, lithe and canoe-like in shape, but with a brutal, trapezoidal 6,000-pound wing stuck to the bottom. And behind this wing of a keel, way back, was a separate “spade” rudder. The design that Bill Lapworth created, at 15,000 pounds, was considered questionable, radically light and dangerously underbuilt by many of the yachting authorities, not to mention its being built out of the avant-garde new boatbuilding material of fiberglass, referred to as “extruded snot” by the esteemed L. Francis Herreshoff.

Griffith and Lapworth unsuccessfully shopped their design around to several California boatbuilders, experiencing polite rejection until they showed the plans to Jack Jensen, who agreed to build the boat on the condition that Griffith could guarantee orders for at least ten boats.

Fast forward to the present, and today the Cal 40 has attained true ‘cult’ status as a design that is sought after, restored and passed down through multiple generations of families. Try searching for Cal 40s that are for sale on Yachtworld and other sites, and you’ll likely come up empty. Folks spend multiple years and a quarter of a million dollars restoring Cal 40s and fitting them out with the latest sails, gear and electronics.

Standing the Test of Time ​

The Cal 40 has endured because it is not only a relatively quick downwind raceboat, but also a sweet-sailing light cruiser that, in the words of Cal 40 owner  Stan Honey , “has no bad habits.” It steers beautifully under autopilot — plus it is rare to find a tiller-steered 40-ft sailboat, especially one with a light helm.

​Cal 40s have twice achieved the record of being the biggest one-design fleet ever in the biennial Transpac Race, with 14 boats in 1966 and 2005. And the boat continues to rack up trophies in big ocean races too, as San Francisco Bay-based Cal 40s have continued to place well.  Azure, Rodney Pimentel’s Encinal-based program, has been consistently near the top of the fleet in Bay, coastal and Pacific races.  Green Buffalo  and  Red Head , from Richmond Yacht Club, have won at the top level. And no list of modern-era Cal 40 accomplishments is complete without mention of the husband/wife team of Stan Honey and Sally Lindsay Honey onboard  Illusion .

​Many Cal 40 restorations are underway, or have happened recently.  Fred Cook ’s complete down-to-bare-glass rebuild of  Sequoia , documented in a great series of videos, is the most famous one. He’s worked with Cree Partridge, Jim Antrim, Kame Richards and other top East Bay pros to create a virtually brand-new boat.

​A Swell Cal 40 Voyage

Perhaps the most well-known Cal 40 belongs to  Liz Clark , who has been roaming the Pacific aboard Cal 40 #68,  Swell . On what she calls, “a sailing surfer’s voyage of awakening,” Captain Clark has pushed the boundaries of solo cruising and sustainable living, all while attracting notice for her exciting adventures and sponsorship from the likes of Patagonia and North Sails. We have a copy of her excellent narrative, a book called  Swell , onboard Shaman .

I own #120, ‘Mahalo’ and have since 2007. Yes, spent lots of $$ but she was in great shape after two Transpacs in ’03 and ’05 as ‘Flying Cloud’. She’s small by modern standards but just a blast to sail. I don’t race but I love to sail a boat well and a 40 is just a joy. She’s a great cruising boat now too.

First I would like to thank Latitude 38 for providing the magazine over the years but its especially great now when away from the water! I did the Transpac last year on Bob Hortons Cal 40 “Highlander” from Tiburon. What a great ride out there on the Pacific, I can vouch for the surfing which became competitive on the boat to see who who get the highest speed, I won by topping out at 18.9 knots on a wave at about 3-4 in the morning!, We could gauge how fast we were going by the noise of the water and how high water was spraying above the lifelines.

I like Cal 40s fine, but not the V drive most of them have.

I remember sailing with Jon Andron and his father Mort on their Cal 40 out of Santa Barbara in 1966-69. I was living aboard my boat GJOA in the SB harbor then. A fast boat ,but many “old school” sailors did not trust the FRP boats and I remember wondering if those boats would just fall apart while racing. How times changed.

We love the Cal40 here on Monterey Bay as well where we have a group of solo sailors we call “The Usual Suspects” who enjoy slugging it out on a regular basis. The Cal40 is extremely well suited for solo sailing/racing with it’s long tiller, accessible trim lines, and ability to easily steer with one’s foot while grinding in the jib after tacking. Just ask Steve Gann on his Cal40, Boomer, who (at 78 yrs young) still has enough tricks up his sleeve to teach us “youngsters” a thing or two!!!

Love Cal 40’s. Sailed in 81 and 85 on Montgomery Street in TransPac. We won it all in 85. The boat is like a freight train on rails downwind in a blow. I have many wonderful memories. I love it that Cal 40’s are still competitive 6 decades later.

How about running some of the old stories about the Cal-40. One such story that comes to mind was about Stan Honey doing the single-handed transpac in his Cal-40. Something about him beating the time of all previous Cal-40’s that had ever done the trip.

Splendid summary, thank you! It is extraordinarily impressive that almost 50 years later the Cal 40 remains an icon: a formidable racing boat that is also a sea-kindly and practical cruising boat without bad habits

It is, perhaps, worth remembering that the Cal 40 did not spring fully formed from George Griffith’s imagination onto that cocktail napkin. The same George Griffith had collaborated with the same Bill Lapworth on a prototype for the Cal 40 which was also built in Cost Mesa. This was the Lapworth 36. George Griffith took delivery of hull #1. It shared many of the same characteristics, and 71 boats were built to become a premiere one design fleet on the West Coast. It too, was radically ultralight by the standards of the day at less than 11,000 pounds. It shared the same rig and sail plan, and many of the same hull and under-body characteristics. The L-36 still had a keel hung rudder so it was the spade rudder that was the quantum leap on the Cal 40. Like the Cal 40, a well maintained Lapworth 36 remains a formidable racing boat as well as a sea-kindly and practical cruising boat without bad habits.

Full disclosure: my Father had #71 built. It is still in our family, and I expect my sons to be sailing her for many decades to come.

So additional articles must follow to describe the “cult” group of Cal 20s, 29s and other Lapworth models such as the Pearson 44, etc…. the man knew how to conceptualize racing vessels way beyond the design of the times.

What about the 40’s hot little sister the Cal 39 (pic in 2-11-18 Lec Lat, Ode to Wet Bottom Girls), or “The Other Woman” Knot A Clew.

Little? I believe the Cal 39 is both longer and heavier. Ask Saildata.com

Unfortunately, SailData.com indicates that only 107 CAL-40’s were built, but I apparently have hull #168 and I believe the above information is correct that 170 were built. Perhaps SailData.com transposed the 7 and the 0 in their count. I have come across a few other errors in their data, albeit they are a very useful source most of the time.

The Cal 39 is certainly a fine yacht, but it is fundamentally an offshore cruiser with good performance rather than a racing design that can also be cruised comfortably.

Guess I could tell a few “old” Cal 40 stories. In the ’67 Transpac (not ’66 as written in the article above), there were 14 Cal 40s on the start line. HOLIDAY TOO, #24, won class and overall, the youngest crew to do so, and a record that still stands despite MORNING LIGHT’s professional attempt at besting it. Before the 2007 Transpac, and movie of the same name, Robbie Haines of the MORNING LIGHT Disney project called me up and wanted all HOLIDAY TOO’s ’67 crew birthdates. I thought this a little strange without an explanation and refused his request. Another memory: Before the 2003 Transpac Stan Honey invited George Griffith and Bill Lapworth aboard ILLUSION for a little visit while tied up at the Griffiths’ dock in Alamitos Bay. As we sat around in the cockpit, a little contentiousness erupted. George told how Lapworth had designed the rig to be 18″ shorter, but George held out for the “tall” rig, saying Lapwoth’s “stump” would have “killed” the boat. Then the subject of who designed the Cal 40’s spade rudder, of which both Lapworth and Griffith claimed credit, arose, and was not resolved before our friendly little reunion broke up. Good times. -skip

Good to read about the history and accomplishments, past and present, of the wonderful Cal 40. My family and I have enjoyed owning Chaparral, hull number 135, for more than two decades and agree whole heartedly with the positive statements and comments about this tried and true class of great sailboats. In over 50 years on the water, Chaparral has proven the point of being an excellent racer and cruiser by performing well in off shore racing, including crewed and single handed Transpacs, as well as sailing around the world in 16 months, with her previous owner, Hans Vielhauer. Cal 40s may be old, but they certainly are good, and so much fun to sail.

Jim Quanci’s beautifully maintained Cal 40 ‘Green Buffalo’ has a few miles and many wins under her keel! I enjoyed following GB out of the gate in the 2012 SHTP, which Jim and GB won. And of course GB has also competed successfully in several Pac Cups, and many Bay races. She’s a Cal 40 worth watching!

Can anyone fill in the history of Sally and Stan’s Illusion? There was a black Cal 40 on the East Coast by that name in the early ’70s – owned by Commodore Montesano and raced by him and Bus Mosbacher. Maybe you’ve enjoyed a famous Montesano Cooler on the lawn at Larchmont. Yup – one and the same. I raced on the East Coast Illusion as a junior and have wondered if it’s the same boat. Thanks for any ideas.

Yes Sally and my Cal40 ILLUSION is the same boat as owned by Bus Mosbacher and Vince Monte-Sano. We sailed ILLUSION around to the East Coast to do the Bermuda Race in 2020 which was cancelled. Our fallback was two terrific summers cruising in Maine. We’ll be racing ILLUSION in the upcoming Newport Bermuda Race in June 2022. Interestingly ILLUSION’s first Bermuda Race was in 1966 raced by Mosbacher and Monte-Sano in which she came second to the Cal40 Thunderbird. The seven Cal40’s swept the results that year.

I am the keeper of hull 147 (I think) under the name EnFin, located on the Great Lakes. Although her specific history has gaps, it’s believed she’s lived in the fresh water of Lake Ontario for all of her life. In my opinion the Cal-40 has the best cockpit and is…. sparse down below. The cramped galley and curved floor can be difficult to get used to, but in a >15kn beam reach she makes it tough for boats far lighter and newer to keep up.

It is the same ILLUSION as owned by Mosbacher and Montesano. Hull number 57. She used to be black. There are half hulls of her in the NYYC Model Room and in Larchmont YC. She used to have sail number 1700, probably because Weatherly, the 12 that Mosbacher sailed in the Cup had sail number 17.

Thanks Stan, that connects the dots and brings back lots of happy memories. Glad to know you’re continuing the fun. Good luck in June. TK

I crewed on an L40 owned by Dr. Ed DuBois out of Marina del Rey back In 1968 and 1969. It was a lot of fun even tough we weren’t very competitive. I’d love to know if that boat is still around. I have no remembrance of the name or numbers of the boat. Ryan Anderson

Was the Dubois L40 also named Duboius? I was best friends with Larry Dubois back then.

I remember racing against Laughing Sally in Puerto Rico early 1970s. Dick Doran was the helmsman. It was the most dominant and professional boat during those days. In 1970 won Antigua.

I’m the current care taker of 1970 built Cal-40 Jubilee. Almost done with a full refit here on the Gulfcoast near the Florida Alabama line. I was really enjoying the ride until starting on the long journey of redoing outside and in. Everything except the engine and transmission have been changed out. About to rig and step the mast soon. Hope to have her ready to go fall of ‘23.

Take good care! I learned to sail on Jubalee in the 80’s in Houston. She’s special. I’ve heard a photo of her was in the Charleston yacht club for a while.

There used to be a small plaque or something on the bulk head commentating a SORC record she set.

I have (should I say am trustee of? lol) a Cal-40 that is apparently Hull# 168, formerly named ‘Callalou’ or ‘Callaloo’, and now named ‘Innisfree’ likely after the Irish poet Yeats’ poem of the same name. I’ll keep her name as is. She needs some deferred maintenance caught up and rehabilitation. The teak is in need of cleaning and oiling and the cockpit backboards will most likely need replacing. The power plant is not original. She has a Westerbeke W-33 now, which was derived from a Perkins block; some parts are interchangeable. The engine starts and runs fine now with a new waterpump. I am eager to get her sailing again as I think she has awesome lines, not to mention all of the Cal-40 history and accolades I am learning more about. Any help with photographs of original cabin layouts, maintenance issues to look for, etc., will be greatly appreciated. Thank you in advance.

Cal 40 is a 39 ′ 4 ″ / 12 m monohull sailboat designed by C. William Lapworth and built by Jensen Marine/Cal Boats between 1963 and 1971.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The accolades for this particular boat are many. Certainly one of the most influential designs and successful racing boats ever. With 160 built, it was also a commercial success for Jensen Marine. Less mention is made of the man, George Griffith, who actually commissioned the design, and agreed to back the construction of the first ten boats.

This added note from Robert VanderPol II: “There is a single example of a raised deck Cal 40 similar to the Cal 25 & 28. Jensen Marine was promised a number of orders. All but one backed out at the last minute and only one was built and delivered.”
