Astus 20.5: Fast, fun and affordable trailable trimaran

For fast yet undemanding sailing, easy trailing and simple camper-cruising, the Astus 20.5 trimaran is likely to find wide appeal says David Harding

Boats that are small and light enough to keep in your driveway and trail to where you want to sail make a lot of sense.

One drawback, however, is that they tend to be slower than bigger boats – especially if they’re of a size and weight that allows them to be easily managed short-hand, both afloat and ashore.

If you want to sail from Poole to Weymouth for the weekend in a 20ft trailer-sailer, for example, it might take a while.

This is where speedy trailable trimarans like the Astus 20.5 come in.

When I sailed its predecessor, the 20.2, about 10 years ago, we regularly hit 15 knots on a reach without breaking sweat and maintained an easy 6.5 knots upwind.

You can cover a lot of ground at those sorts of speeds.

I first met the Astus 20.5 at the Düsseldorf Boat Show in 2019. Since it’s a newer boat and designed by no less a design team than VPLP, I had high hopes that it would offer even more than the 20.2.

Quite apart from the sailing potential, the trailing is as simple as can be with a boat like this.

If you choose the resin-infused hull, the Astus 20.5 weighs under 500kg (1,100lb), or just over 500kg with the standard solid laminate.

The lighter weight means you can use an unbraked trailer , saving money, maintenance and yet more weight, so you can trail it behind a normal hatchback vehicle.

Getting somewhere fast under sail is one thing. Having somewhere to sleep when you arrive is another.

Though its cabin is smaller than on a monohull of similar size, the Astus provides seating, stowage and space for a companionable couple to be able to stretch out.

Then of course you have the trampolines each side on which you can rig a tent for more sleeping space.

The opportunity for a sail on the Astus 20.5 finally came when Hein Kuiper of Boats On Wheels brought his first demonstrator to the UK.

In fact we went out twice – first for a photo session in Poole on a brisk winter’s day and then a few months later in Chichester Harbour.

Since the boat arrived in Poole on its trailer, I was able to see how it went together.

Pulling out the hulls is pretty straightforward: their aluminium beams slide in and out of the fixed beams on the main hull. You can do that ashore or afloat.

There’s nothing complicated about raising the rig, either, and it can all be done singlehanded .

The whole process, from arriving with the trailer to sliding the boat into the water, took Hein a couple of hours or so the first time or two (comparable with a monohull of similar size, he reckons) but would undoubtedly get quicker with practice.

Whether you choose the standard or the Sport version, the mast is the same height.

The difference is that the latter comes with a square-top mainsail to give appreciably more sail area.

If you want to save as much weight as possible and make raising and lowering the mast easier, you can have it in carbon. A wing mast is another option.

The rig and hardware don’t appear to be modified in any way as a concession to the boat’s trailer-sailer nature.

Here and there, the odd ready-made loop or strop would save fiddling around with bits of line.

All that is forgotten as soon as you’re under way.

On our second outing, once the electric outboard had pushed us out of Northney Marina – where the boat proved to be surprisingly manoeuvrable with the centreplate fully down – we headed off on a beam reach at 12.5 knots in 12-15 knots of wind.

In most boats, 12.5 knots would be going some. In this 20-footer, it felt perfectly relaxed.

Over the course of the following couple of hours we covered every point of sail including, of course, reaching under spinnaker.

With the gusts rarely exceeding 16 knots in the flat water of the harbour, we didn’t quite manage to break 15 knots.

It wasn’t a bad speed-to-effort ratio nonetheless.

The boat felt rock solid the whole time, and I knew from the photo session in Poole that she could carry the kite on a beam reach in appreciably more wind than we had in Chichester.

It’s hard to imagine that 20 knots wouldn’t be perfectly achievable.

Upwind we maintained between 7 and 8.5 knots most of the time.

As you would expect, you need to keep the bow down a little to maintain full power.

You also need the purchase of the 6:1 mainsheet to maintain sufficient tension in the upper leech. It makes a big difference.

Tacking was pretty positive provided we had adequate boatspeed going into the tack, and leeway appeared minimal.

All told the Astus 20.5 was great fun to sail and easy to manage two-handed.

There was little for a third person to do except enjoy the ride or contribute to the righting moment by joining the helmsman on the windward trampoline.

If you were racing, you could use a longer tiller extension and fit toe-straps to maximise the advantage.

Beating our way back up the harbour, we demonstrated the windward ability of the Astus 20.5 by sailing straight past a 15m (49ft) monohull.

Creature comforts aboard the Astus 20.5

Above decks the Astus offers a vast amount of sitting and lounging space thanks to the trampolines.

Down below, the hull’s narrow beam makes things cosy but you still find a seat either side, space for a chemical toilet under the aft end of the berth and a fair amount of stowage beneath and to either side of the companionway.

The centreboard is offset to port to leave the middle of the boat clear.

The finish is simple and uncomplicated, largely to save weight. There would be plenty of scope to fit a slide-out galley and devise lightweight stowage solutions to make better use of the space.

Astus 20.5: the test verdict 

More than anything else, this boat is tremendous fun.

She feels taut and responsive to sail. I found that it took an hour or so to begin to find her sweet spots, but after that she just makes you want to sail her.

She inspires confidence and is easy to handle, too. In most conditions you could manage perfectly well single-handed and for cruising you won’t need more than two.

Plan of Astus 20.5

The Astus 20.5 has less accommodation than a monohull of similar size

Then there’s the speed. No matter whether or not you’re in a hurry to get anywhere, it’s easier to slow down in a fast boat than to speed up in a slow one.

Speed is fun in itself, and it’s hard not to enjoy sailing straight past a monohull more than twice your length.

Niggles are relatively few.

I thought the rudder blade could do with a touch more balance and I wasn’t sure that the fixed end of the 2:1 jib sheet was quite far enough aft on deck.

Other than that, it all works.

Hardware is mostly from Harken and the spars are by Sélden, so there’s no skimping in these departments.

Would she suit you and your crew?

The Astus 20.5 will attract attention. Several people stopped for a chat and to admire her back in Northney having seen her on the water.

If you’re a dinghy sailor moving up but not ready to slow down, this is a good choice.

Just as much interest is coming from big-boat sailors moving down or wanting a second, smaller boat that still has a good cruising range. Few boats of this size go so fast with so little effort.

Astus 20.5 diagram

The Astus 20.5 is ideal for exploring harbours, estuaries and rivers

As for the inevitable monohull-versus-multihull debate, there are trailable, family-friendly boats of this size with one hull that sail very nicely.

I have clocked over 12 knots in one or two, but only under spinnaker, with good sailors on board and not for sustained periods.

As long as you’re prepared to accept that sailing regularly at double-figure speeds means sacrificing some interior volume, the Astus could suit you perfectly. And for exploring harbours and estuaries, camper-cruising and nudging into the beach, it’s absolutely ideal.

Best small cruising trimaran revealed

Best small cruising trimaran revealed

A trimaran is a boat categorized as a multihull. What it means is that this particular vessel is composed of three hulls that aid the boat during sailing but also provide interior spaces for the crew and guests to enjoy.

Trimarans are very popular in the sailboat market. They are mainly appreciated for their speed but also for their cruising character that can address families’ interests as well. Trimarans allow for leveled sailing, ample deck space, stability, comfort, shallow draft, and most importantly the good old family fun time.

A small cruising trimaran is probably one of the most popular boats nowadays as it provides an affordable but also an interesting way how to spend your free time and enjoy what nature has to offer. Let’s get to the gist of it then. Which is the best small trimaran nowadays?

Most popular small cruising trimaran

The best small cruising trimaran so far remains the F22 . The F22 Trimaran is designed by Ian Farrier and built by Farrier Marine company. It features a swan design and can be purchased in two versions, racing or cruiser form. This is a small trimaran that includes many interesting features within a compact space. It has a slightly offset centerboard trunk that allows for an ample interior.

In addition, it has an ama folding system. This is an advantageous feature as it allows the ama beam strength to remain to a maximum while the interior is free from any structural support structure for the beam. Fly spray is also reduced due to the folding struts being carried higher than before in case of deployment. This feature allows the F22 trimaran to have a greater performance under sail.

This small cruising trimaran comes in two versions, either with a carbon mast or an aluminum one. In addition, it is equipped with a boomless mainsail furling rig which makes sail handling easier. Most importantly, sailing efficiency is not sacrificed in any case.

What makes this boat the best small cruising trimaran is the fact that it can be used as a cruiser due to its interior. The galley has a two-burner Origo stove, a small sink, and a stow for sailing. In addition, the companionway has a pop-top that increases the headroom. Moreover, the F22 is equipped with a small chemical toilet that is quite private due to a roll-up screen and bulkhead that can be folded. All in all, the F22 contains 4 berths and can be used by families as well.

Compare the best small trimaran with other multihulls

You can learn more about the F22 trimaran on TheBoatDB . TheBoatDB provides an organized platform that anyone can use for free with a no time limitation account or what we like to call a “Forever free account”.

You can compare the F22 to other trimarans or even catamarans and single-hull boats and see for yourself whether this boat is up to the challenge for you. In addition, you can shortlist this trimaran or select a few different boats for future references. All in all, you will get your boating life on one platform as we like to say!

The new "Mini Trimaran" as it is being called (for now) is an evolution of our work in small multihulls over the years. It combines elements of the successful  Expedition Sailing Canoe  and the " kayak trimaran " named 'Spongebob' into a new vessel. Hull #1 was cut out as a CNC kit in July 2020 and is now in the process of going through sea trials. Click here for Construction  Photos of hull #1   You can get a sneak peak of the builders guide here .

Features of hull #1 included a roller furling mainsail and headsail for easy reefing and a boom for superior sail control. For Hull #2 we went back to a non rotating mast with slab reefing and single line reefing instead. The amas retract into the center crossbeams to reduce the overall beam for trailering without having to demount the amas. A stern cockpit with a large kayak style cockpit coaming can be used with a spray skirt. Steering is accomplished with foot pedal controls or a tiller. The boat can also be sailed from the center cockpit and there is optional space to install a hobie mirage drive in the center cockpit. Ample storage for a full expedition load. The center cockpit is flanked by a pair of "wing decks" which are large enough for sleeping aboard with a bivy or cockpit tent. A leeboard is controlled with lines running to the aft cockpit. The hull incorporates an integral spray chine above the water line to increase cockpit comfort while maintaining a narrow waterline beam of 19 1/2" 

Length: 18’ 6” Sailing Beam: 11’ Trailering Beam: 6’ 8-3/4” Working Sail: 100 sqft Optional Spinnaker: 80 sqft Empty weight: ~290lbs Gear/water capacity: 150lbs Full Load Displacement: 620lbs (solo) PPI: 117lbs (pounds per 1” immersion Ama buoyancy: 275lbs

Latest News: Plans and a CNC kit for this design are coming soon. Hull #1 and 2 are currently in testing and prototyping phases and we look forward to improving the design of the rigging and kit for future builders. 

Video from first Sea Trials in Jan. 2021. We were very pleased with the performance and look forward to further testing the rigging and design in preparation for releasing plans and kits for this design. You can note in the video that the boat is being sailed totally empty so the bow rides a bit high. 

Hull #1 made the trip to the 2021 B&B Messabout and we had a chance to test here out. 

Hull #2 was completed and launched in January 2022. Changes to the design include adding some legroom to the aft cabin, and including space for a hobie mirage drive well in the center cockpit. Hull #2 does not have a roller furling mainsail but instead more traditional slab reefing. A Core Sound 17 mainsail is now the primary working sail and a furling code zero is again used for light air and an off the wind boost.

Are you really considering buying or building a small trimaran?

Report Cover

The first one was called Small Trimarans and then More Small Trimarans followed later. They both include some interesting interviews, some with well known and reputable designers.

But as interesting a read as they are, they were missing the technical data, critical reviews and comparisons between the small trimarans under discussion. So when editor Joe suggested I might just be the most independent person qualified to do this, I decided to take on the task.

The result is a 22‑page Technical Report that not only compares many of the tris in Joe's books, but looks at the data for many more—a total of 20 in fact, all between 19' and 25' in length. Twelve (12) of these are reported on with a critical look at what they might offer YOU the potential buyer—all in numerous pages of text with color photos.

I also included two useful charts showing average building times and cost for tris of different lengths as well as a 2‑page spreadsheet with LOADS of data about each boat—things that will keep you busy for hours!

Although this had to be a somewhat personal look, I do bring 60+ years of sailing experience to it, as well as a lot of past boat building and designing as a qualified naval architect and engineer. I invite you to check some of the articles on this site to get a feel for whether you think I can help you or not. But just to make SURE I was on the right track with this, I first sent it out to five of the most reputable small multihull designers in the world who with just one exception, were not directly involved with the Small Trimaran boats—so could say what they wanted, quite independently.

So here below, also with a sample of the report, is what they wrote back to me, and I hope this will remove any doubt in your mind that the report is indeed worth reading.

My report is available at $9.00, complete with graphs and spreadsheets. On payment, you will receive the report by email, usually within 24 hours. It comes in PDF format, so that you can print out at home in full color. As one reviewer already remarked, this is about as close as one is likely to get to an independent consumer report on small tris!!

The 20 Small Trimarans included in this Report are the A21, Cardiff 21, Corsair Sprint, Day Tri 20, Discovery 20, Farrier F22, K24T, Hughes KH‑23 & KH‑24, Kolibri 23, Leneman L7, Magnum 21 & 21S, Ostlind Z65, Scarab 22 & 670, Spitfire 20, Tremolino, Trinado, and the Warren 23.

Here is what some very well-known designers had to say about this report:
