The i550 is a simple to build Sport Boat which will deliver outstanding high performance.

Have you always wanted a performance sportboat, but didn’t have a performance sportboat wallet? The original i550 was created for the MicroTon class, and has since been upgraded and redrawn as a one-off sportboat for fleet racing.

It’s ease of building for the amateur builder with “stitch-and-glue” method ensures a light, solid hull, and a quick build for even those with NO boat building experience.

i550 sailboat specs

Due to it’s simple construction method, there’s not much to the construction process. The whole thing can be cutout, and “stitched” together in a weekend. The construction process is fairly simple and straightforward; The wood panels are cutout and “stitched” together in a string jig to keep the boat symmetric. Once the boat has been stitched, the open hull is left right side up, and the seams glued with glass tape and epoxy. Frames are set in the boat, and taped with epoxy in place. The whole interior can then be epoxied and finished before adding the decking.

Decking comes next, then the hull exterior itself. The boat is still light enough in this stage that it can be easily turned over with the help of come friends. The bottom faired and finished and the hull turned back upright. Rigging is added, and any interior details come next. Sounds simple? That’s because it is. Total build time is typically about 200 man hours.

There is room down below for simple accommodations, and “camp style” sleeping. Plenty of room on deck ensures comfort both up and downwind. A bulbed keel gives stability and righting moment while allowing the boat to keep dinghy like performance.

The plans pack consists of: Construction Notes, Suggested Bill of Material, profile, plan and section views, nesting diagram, hull panel diagrams, frame diagrams, interior piece diagrams, keel and keelbox diagram, rudder diagram, cabin trunk diagram, deck layout diagram, and a rigging diagram. The plans pack is all A sized drawings in a easy to work with binder. Plans include both the standard, and extended cockpit version.

The rig can be obtained through a number of sources. We’ve put together a rig package for North American builders available upon request. Additionally, we plan to offer hull kits, and keel bulbs in the not so distant future. Check back soon for more information.

This boat has been built in 3 sizes, ranging from the i550, to the MG25, to the MG30. Plans are currently being redrawn for the latter two models and will be available soon. There are also a number of other designs coming; a smaller 15 foot sportboat, that is in the works, check back in the coming months for more details on these projects.

This is a great way to afford a high performance sport boat at a fraction of the cost of other offerings of this type of sailboat. If the builder is resourceful it can be sailing for less than $5,000. If the builder uses all the best brand new sails, mast, hardware and a trailer it can be sailing for $9,000.

It is fast, speeds in excess of 16 knots are quite possible!

Several of the photos in this article were submitted by Andrew Clauson in Australia. Andrew built the boat in a few seasons time, and will be racing other 6m sized sportboats. For more information on Andrew’s project you can visit his website at:

Description:

The i550 is easy to construct, even for even the amateur builder, with a plywood "stitch-and-glue" method that ensures a light, solid hull, and a quick build. Or, to save drawing and cutting time, you can buy a kit from us, cut from the master templates or full-size paper patterns that are very accurate.

The i550 is annoyingly fast and has troubled much larger sportboats, like Elliot 7’s and a Melges 24.

The first i550 was launched in Australia a few years ago, home built by Andrew Clauson. It is the fabled Tokyo Trash Baby of YouTube fame.

The i550 is a big winner in the bang for the buck department. You’ll not only have the satisfaction of crafting your own sportboat, but think of the $25 or $35 thousand dollars you’ll be saving. Resourceful scavengers can put one together for $6,000 or less (US). Double that and you’ll have a carbon spar, fine sails, nice foils by a skilled maker and new everything. The building time typically spent comes in at about 400 hours for the hull, keel and rudder.

Following the plan set page by page, with the parts diagrams and instructions, the boat will come out right.

The rig has height and length limits, but the layout of the deck and cockpit are open to interpretation. Construction is simple stitch and glue plywood, epoxy and glass. Two people can have the hull looking like a hull in a weekend.

Put in the transom and bulkheads next while it is right side up. Epoxy coat and glass tape the parts in place and roll it over. Fair the bottom and fiberglass cloth it. There is room down below for simple camping style. Plenty of room on deck gives you room to move around. The lifting bulb keel gives stability and righting moment, but, most importantly, lets the boat launch easily at any boat ramp.

The plan’s pack consists of construction notes, suggested bill of materials, profile, plan and section views, nesting diagram, hull panel diagrams, frame diagrams, interior diagrams, keel and keelbox diagram, rudder diagram, cabin trunk diagram, deck layout and a rigging diagram. The plans pack is in a notebook-ring binder. Plans include both the standard and the extended cockpit version. Some creative builders are even building flush deck versions, and the Portland Group, who formed the North American Class (NA.org) have perfected the rounded flush deck version.

The mast can be obtained through a number of sources (both aluminum and carbon fiber). We will soon be offering keel bulbs and keels, ballast bulb molds and rudders. We also will build the i550 for you to any stage of completion. Clubs are especially encouraged to inquire. Before and after any purchase, Also, we are always here to answer your questions, anytime by email or phone. Five are now sailing in Australia. Many other builders, who have bought kits or full sized paper plans, are making great progress and we expect those i550 s to start launching soon.

Sailboats - Racing

I550 sport boat.

The i550 is a very popular 18 foot stitch and glue design. Simple construction and avid builder blogs and websites add a sense of community and support for the builder. It is sloop rigged with an asymetric spinnaker and the powerful sailplan is modern and controllable.The Gougeon Brothers (West System Epoxies) liked the design so much they built one for themselves and made a speed build video of “Hot Canary” in their shop. There are about 500 plan sets in 40 countries and 6 continents.For more information: i550sportboat.com, [email protected] , i550class.org, i550na.org.

Building the i550 Sportboat HOT CANARY

By ben gougeon.

An autopilot steering failure on his sailing scow  Yello Thing  forced Meade to withdraw from the 2010 Everglades Challenge . When he reached the shore, he was already thinking about building another boat for the next race.

Slappy, one of the boatshop cats takes a last stroll around the deck before Hot Canary heads to Florida.

Slappy, one of the boatshop cats takes a last stroll around the deck before Hot Canary heads to Florida.

The next boat needed to be more substantial to handle rough seas. It needed to be trailerable and comfortable yet still meet the race’s natural requirements. Meade and Jan began looking into the i550, an 18′ sportboat designed by Chris Beckwith. The pair decided that with a few modifications the i550 would be perfect for the race. They ordered the plans and construction began.

The i550 Sportboat Solution

The Gougeon Brothers technical staff constructed the hull in their shop with Captain James R. Watson overseeing the building process. The i550 sportboat is built with plywood stitch and glue construction. We used ¼” 5-ply Okume plywood and judiciously placed 5 oz carbon fiber. The entire boat was built with WEST SYSTEM® 105 Epoxy Resin® and 207 Special Clear Hardener® .

With all of the bulkheads in place the ties were cinched tight before fillets and fiber-glass tape were applied to reinforce the joints.The next boat needed to be more substantial to handle rough seas.

The i550 sportboat’s bulkhead is stitched in place with zip ties.

The first task was to scarf three 4′ × 8′ pieces of the marine plywood together using the WEST SYSTEM 875 Scarffer™. We constructed a simple jig to enable the proper cut point on the plywood to minimize waste. After cutting the panels, we bonded them together with a mixture of 105 Resin and 207 Hardener thickened with 406 Colloidal Silica filler. Then we lightly sanded the panels with a random orbital sander to clean the scarf joints and prepare the surface for a coating of 105/207 mix. We “flow coated” the surface by applying mixed epoxy with a 10″ drywall knife. This was an efficient, yet effective method to coat three 22′ × 4′ panels with epoxy prior to construction.

With the panels coated, we overlaid the Tyvek™ patterns (provided by Watershed Sailboats) on the panels and made reference marks to transfer the pattern shape for accurate cutting. Using a handheld jigsaw, we cut the patterns from the panel, careful to leave the original reference marks intact. It’s always easier to remove extra material later than it is to put it back on.

Captain JR Watson built an ingenious jig we used to set a scribe mark around the perimeters of the cut and trimmed panels. From this point, we drilled holes at 8″ intervals to allow for the HDPE zip ties to “stitch” the panels together.

We loose-fit the panels with the zip ties in place to achieve something close to the desired hull shape. With bulkheads fitted in the same manner, the i550 was starting to look like a boat.

The daggerboard trunk was fit in position after the bulkheads were in place. Gray pigment was added to the fill coat of epoxy over the fillets.

After cinching the zip-ties we added some spacer modifications to the bulkheads to alter the hull camber midship and forward of midship. We tabbed the seams with WEST SYSTEM 732 Episize 9 oz fiberglass tape. When the epoxy had thoroughly cured, we removed the zip ties.

We then completed the cockpit, deck, stem, and stern using techniques detailed in the book, The Gougeon Brothers on Boat Construction. After completing the hull, we moved the boat across the street to the Gougeon Brothers boat shop for Meade and Jan to finish. They made a few modifications and customized the boat to fit the needs of the race. The i550 sportboat is a one-design class that allows modifications.

The first thing we looked at was the bulb keel called for in the plans. Because we needed a shallow draft, we built a straight keel that fully retracts into the hull. This flush keel arrangement is ideal for moving the boat over land. The Everglades Challenge requires all boats to be manually moved from the beach to the water.

We cast a NACA 12% lead foil and attached it to a board with the same section. An aluminum crane fitted with a winch lifts the keel through the daggerboard case. This arrangement provides a sufficient mechanical advantage for one person to raise the keel to the desired height. The boat can be sailed with the keel up, down, or at any position in between. When portaging, the keel would be raised until flush with the bottom. The keel allows for sailing in shallow waters and for it to be easily trailered. With the keel cranked all the way down, the i550 is very seaworthy and has tremendous righting-moment.

Meade and Jan will use three heavy-duty, reinforced 10″ × 48″ beach rollers to move the craft over land. The rollers, stowed beneath the cockpit, serve double duty as positive flotation.

The next thing we focused on was the rig. We bought a 25′ 6″ carbon fiber mast from C-Tech in New Zealand. Because the rig has to be lowered during the portage and pass beneath a 10′ high train bridge, we fitted the craft with a tabernacle instead of a standard mast step. This tabernacle allows one to raise and lower the mast without assistance. No gin pole or stay guides are required. All internal halyards pass into the tabernacle and route to the cockpit.

Meade Gougeon rolls a coat of paint on the overturned hull of the i550 sportboat, while his brother Jan follows up with a tipping brush.

Ben Gougeon demonstrates the blowout safety feature of the rudder with a moveable trailing edge tensioned with a shock cord.

The aluminum crane fits into a slot on either side of the hull and can lift the keel for sailing in shallow water or trailering.

The bowsprit of the i550 sportboat is hinged at the bow and attached to a crossed line at the base of the cockpit which will allow it to pivot 30 degrees.

The Rudder Assembly

Because the rudder was the major source of malfunction on Yello Thing, Meade knew the i550 sporboat needed a forgiving steering system. He designed a daggerboard-style adjustable draft rudder with a blowout safety feature. The rudder foil is set into a case with a non-destructive breakaway system that involves a moveable trailing edge tensioned with a shock cord. The boat can be sailed with the rudder fully extended, or in shallow water, partway up. This rudder configuration eliminates any chance of damage when grounding, while retaining a balanced helm at any depth of rudder setting, permitting shallow water control.

Instead of a retractable pole that protrudes from one side of the bow, common to sportboats, we experimented with a pivoting pole that can be adjusted off-center up to 30° for better downwind performance. The bowsprit is hinged at the bow and attached to a cross-line at the base of the cockpit. This allows the spinnaker to be articulated from inside the cockpit.

With this final change complete, the i550 is now ready to take on The Everglades Challenge. We wish Meade and Jan, along with all the participants of The Everglades Challenge, the best of luck this year.

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)

This past winter I got hooked on a small sportboat called the i550. It's a stitch and glue plywood screamer that is quickly growing world wide. The boat can be built from plans, kit or from full size patterns. I chose to loft my own since I had enough Okoume plywood to built the boat. There are class rules which are have plenty of room for error for the first time builder. There are two cabin length options and the designer has chosen to build his with a flush deck. Needless to say, I have pushed the envelope a tad and heavily modified mine, while keeping the boat class legal. I kind of wish they mandated a cabin but if someone was going to build a flush deck screamer, I had to do it as well. The first boat, Tokyo Trash Baby is well known and has several fantastic Youtube videos which will certainly get one's attention. The boats do have an interior and if you don't mind cramped quarters, berths for a small family of four. Full kits are somewhere near $2,500+- and plans, including official class hull #s are only $75. They claim build time is around 200 hrs, but I have at least that much time staring at the boat wondering what to do next. It has been a blast to build and the class involvement and contribution is second to none. The boat is has a retractable bulbed keel and can be ramp launched with ease. Total sailing weight is 800 lbs. No restrictions on materials, but plywood is best. I had a tough time with the stitch and glue because of my background of hard plug construction, but got it done and feel prouder of that accomplishment than any boat to date. Class website for any interested: http://www.i550.org/index.php My boat (have not updated photos for a few weeks) : http://s119.photobucket.com/albums/o145/Tynaje/222/ Tokyo Trash Baby video (several to choose) : http://video.google.com/videosearch...&q=tokyo trash baby&um=1&ie=UTF-8&sa=N&tab=wv # Hull # 107 video : http://www.youtube.com/watch?v=-Iux...=view&catid=2&id=2931&feature=player_embedded I don't think a person could get into any boat with this kind of performance, stability and fun for the buck. It can also be detuned a bit for family trailer fun, 107 has reduced sail area and rig height I believe. Peter

I really like the concept behind the i-550. I would like to see plans for something similar, but slightly bigger with some basic accommodations (one burner stove, porta-potti, small double berth). It would be for coastal cruising, and occassional offshore hops. (no transat though lol) What I really like about the i-550 is the chined plywood S&G hull is easy and fast to build, I like its lifting keel, and obviously its planing hull/high speed. Oh, and it is lightweight enough for me to trail it without a huge SUV. Lucas was offering plans for a chined mini 6.5, but his website is down and I don't know where to find specs and plans for it. Plus I doubt it has a lifting keel, and trailering that may not be realistic. Is there anything out there similar to the i-550 but with more cabin space???

Not what you want to hear, but ... There are almost as many designs in this range as there are designers. Given today's economy, you can buy a used 25-30' weekend style boat for far less than the materials to build one. And you don't have to sand and fair for weeks. Scary but true is the fact that you can probably BUY a complete used boat for the parts necessary to rig a new build - at half the price of buying the rigging a piece at a time at the chandlers. It is absolutely staggering what masts, booms, sails, standing and running rigging, line and foils cost. Building a boat can be a life-changing experience, but do not do it because you think you will save money, end up with great value or be able to sell it for double what it cost. Build because the build process delivers some value to you other than the boat - if building is just a means to an end you are way better off to buy. You might want to look at PAR's designs, Graham Byrnes designs ( B&B Yacht Designs ) - There is an area to this site where you can find hundreds of designs and designers . One thing to note about the conversations here - many of the designs discussed are NOT real, have NOT been built, and have no existing class for racing, socializing or resale value. You have to separate the vapor-ware from the real thing - or you could spend a lot of time and money talking to the wrong people. Don't dismiss racing because you aren't interested - racing one design classes and PHRF racing is the single best way to have some confidence in resale value and adding a very important social scene to your participation in the sport. My club has a sad stretch of dock where all the misfits, orphans and many one-off homebuilts live - make sure you would be happy there instead of with a group of friends. Take a very hard look at your requirements - and available budget. If you've got less than $10-$20,000 to spend - don't consider a new build - you can buy a used boat for a fraction of that. I hate to blow away the romantic dream and thoughts of glistening varnish, but you are looking at hundreds of hours of hard dirty work. Then again, I like to build boats. -- CutOnce

Peter, you'll have to refine you desires a bit, which will help narrow your search parameters. The the general size range I think you're looking for and as CutOnce has mentioned, there are literally thousands of choices. The 18' to 20' range is the largest of all and there are lots of options. Your desires have some conflicts, such as cabin accommodations, porta-potti, V berth (assumed) and a light weight go fast package. There are preformance oriented cruisers, but they'll get eaten alive by a i550 if similarly sized. Look around, there's plenty to select from once you refine your SOR. Have a look at the Vagabond 18 (> http://www.bateau.com/studyplans/VG18_study.htm?prod=VG18 <), which is the same length, but has accommodations in a preformance oriented package. Or her bigger sister the Vagabond 20 (> http://www.bateau.com/studyplans/VG20_study.htm?prod=VG20 <). Both are considerably larger then the i550 in terms of hull volume.

peterchech said: ↑ .. like the concept behind the i-550. I would like to see plans for something similar, but slightly bigger with some basic accommodations (one burner stove, porta-potti, small double berth). It would be for coastal cruising, and occassional offshore hops. What I really like about the i-550 is the chined plywood S&G hull is easy and fast to build, I like its lifting keel, and obviously its planing hull/high speed. Oh, and it is lightweight enough for me to trail it without a huge SUV. Is there anything out there similar to the i-550 but with more cabin space??? Click to expand...
Sounds alot like what I'm looking for Michel. Problem is I just think that once you get into mini 6.5 sizes, the costs begin to explode. We are talking about 6K for an i550 if you're a good scrounger, and at least double that for a ply mini 6.5 (assuming rig/etc are not the top of the line race-ready sort, which would cost much more) I spoke with Tim, license holder of the i550 plans. Apparently there have been alot of requests similar to mine. One guy modified the boat by making it a foot longer, but the balance wasn't got just right and the boat would occasionally round up under spinnaker. He suggested I may want to extend the cabin out to the gunwhales to get some more interior space. He says there is sitting headroom, though from the looks of it he means sitting with your legs directly in front of you, so I'm not too sure how a porta potti would work for the girlfriend... He's gonna try and set me up to check out an i-550 in the northeast. I can't commend the customer service enough, he answered my questions and more, and then responded within hours to my e-mailed questions.

Hahahaha that reminds me of my dog. As a puppy my girlfriend fed it boiled chicken and rice because it didn't want to eat dog food. Eventually this had to stop, so against my girlfriend's wishes I insisted that only dog food be left in her plate. She would get hungry eventually... By day two the pup was crunching happily on her kibble Keppler died from not taking a piss? haha it is incredibly difficult to balance a kayak and take a piss I suppose but come on ;-)

So, here it is. The Coastline Flyer 6.5 Hi Peter, here it is what you want. My first concept of a simple, very fast, easy and cheap to build, campcuiser with useable space inside. The design title is: Coastline Flyer 6.5 Accomodation: 3 to 4 full size berths, 4'+ inside sitting height. lifting keel with draft from 1' fully retracted to 5' 6'' maximum. Intermediate position for sailing in shallow waters is possible where you want to have it. A lightly built boat should come out of the shed with 550 to 580 kg (~1210 - 1280 lbs) boatwheight, a displ. of 950kg (2090 lbs) giving a payload for crew and gear of 370 kg ( 814 lbs). Check out yourself if it is much more expensive than the original. The biggest cost factors are: - max. 25 sheets of 1/4'' and 3/8'' marine ply, for hull, structure, deck, cockpit, deckshouse and basic interior. 2 sheets less if you can get 2 sheets of 10'x5'x3/8' for the bottom. - local grown lumber, no exotics ~ 60kg of Epoxy (West 105 or similar) ~ 300 - 350 lbs leadballast ~ 30 yards 6 oz glas sheeting ~ mast 28 to 29'', can be taken from a Soling (or similar) open keelboat modified to fit the boat. double spreader (18footerstyle) rig, no backstays. -three small 1 gear winches, traveller, gennaker boom from reinforced windsurfer mast, The renderings shown are absoutly preliminary to get an first impression, not faired yet. Calculations are done with safety factors. The rig plan is a handmade sketch to show how a 8.8m (29') mast will look on a 6.5m boat. Have Fun with it! Happy dreaming, Michel
