9m Trailerable Catamaran MkII

Plans for the MkII version of the mini cruising catamaran have now been released. Folding beams, carbon fibre bow poles and full set of sails are also now available for purchase.

The new plans have been reduced in price to $AU990 (a saving of several hundred dollars from original price). To view more information about the MkII [Click Here], to view pricing list, [Click Here].

Updates include a taller mast (now 11m) along with a modern square top mainsail, mast moved forward to allow easier access to double bunk, slightly deeper forward hull keel, extra 10% area on centerboard, extra reinforcement at hull beam attachment (port and starboard hulls only) and removable carbon fiber bow pole with no need for additional stays.

This website will close at the end of December. s-boat.com.au will continue with S-22 Trailer Catamaran updates.

Update 5/9/2016

I have decided that it’s time to reduce my work load. This web site will cease later this year, after the reluctant sale of S-22 Jaguar. I will be content to design and build a 5.5m horizontal folding Trimaran for my own personal use, with the expectation of spending more time travelling and quality time with my family.

There simply isn’t enough time and resources available to fully develop and promote the Power/Sail project that I have mentioned previously. This and other concepts have also ceased.

Recently I trailered Jaguar by myself on a nearly 2,000km round trip to the Audi Hamilton Island Race Week. My 2.5l Diesel van towed Jaguar easily with a fuel cost of only $380. This was a good offshore sailing test for Jaguar as we beat to windward at 9 and 10kts in large chop produced by wind against strong tidal currents. Being the smallest racing multihull competing by far, Jaguar wasn’t able to match the other, much larger, boats in performance, however I was happy with its structural integrity as we pushed hard in a variety of off-shore conditions.

The Nacra rudders, mast, rigging, centre board operation, nets and bow pole performed exceptionally with no noticeable twisting of structure. The radical bows, that I had always planned to update after some serious sea trials, performed as designed keeping the bows from digging in downwind and possibly pitch poling as so many of the very sharp / low buoyancy racing cats do when pushed too hard.

Jaguar, while sailing downwind at 14kts, did run into the back of waves in front but immediately popped back up as designed.

I have now formulated a new updated bow which will see the bow extended and vertical bow section raised making the whole bow a little finer which will add some extra speed. Jaguar will be up for sale once new bows are completed and can be delivered or you can simply hook it up to your vehicle and drive away.

Jaguar is an exciting boat to sail and in the hands of competent sailors will continue to win races with its competitive OMR rating of 0.786, or just as a fast weekender for non-racing events.

JAGUAR FOR SALE $AUD 45,000 (negotiable) also hull molds, mast spreader mold and center board mold are for sale and I will accept any reasonable offer. Also for sale are 4 wing masts x 10m long @ $1,100 each.

S-22 Production Underway

Initially the S-22 will be available in a basic kit (2 hulls, centre cockpit, and folding beams). Other items will be available including netting, rudders, centreboard, mast, sails and customised folding, full bimini cover.

A quote from the new owner of Zeavard

We are very happy with Zeavard now that we have given him a bit of a work out in our local waters. We now realise that a catamaran handles in a very different manner to a mono-hull. I have sailed Zeavard in some strong winds and some light conditions and we are becoming respectful of the way he handles. I'm impressed with the pointing ability of the yacht as it is as good as or better than my old boat (mono-hull). Also the speed is so much better allowing us to cover a greater distance in a shorter time.

Zeavard's owner report: Zeavard has become an important part of our pleasurable life over here and we are getting a lot of enjoyment out of our sailing on Zeavard.

S-22 Trailerable Catamaran


The all new hulls are well on their way and first photos should be available in November. The plugs and moulds are nearing completion.

After a lot of research I have purchased a lightweight aluminium wing mast. The idea of an all carbon-fibre mast is on the back-burner due to the costs involved and also due to the difficulty acquiring reasonable insurance. Although the carbon-fibre mast is something I am not currently focusing on, it may be available as an option at a later date.

A good quality set of sails have been organised. The sails are being offered at a great price which, with the saving of using the aluminium wing mast, will total over ten thousand dollars.

Nacra, who for the past 30 years has led the way in small off the beach racing cats (also a 36’ cat), have developed a new rudder that is a joy to behold. Yes, my all new S-22 will have the best rudder system on the market.

Looking further forward, to the new year, I will have a Shopping Cart setup with internet based payments for S-22 items

Solo Around Australia Attempt
First Leg

(Track for second leg is currently unavailable)

Len's Voyage

After surviving a violent storm 90nm northwest of Cape Leeuwin, WA I have decided to end my solo around Australia voyage after sailing 5,340nm (almost 9,000km).

Time permitting, with a decent window of reasonable weather, Zeavard could complete the circumnavigation, but due to work commitments, family and the need to get started on the new S-22 project it is not possible at this time.

Zeavard will now be put up for sale at the Port Bouvard Marina, 100km south of Perth, WA (Update: now sold). This sale will help fund my new project being the S-22 high performance folding catamaran which I will make available as a kit version with complete boat on trailer at a later date.

Sea Trial

Zeavard’s “Fairdinkum” sea trial of 5,340 nautical miles (nearly 9,000 kilometres), sailed over fifty days, on my attempt to sail solo around Australia. 

This proved without a doubt that this mini coastal cruising catamaran is a very capable and seaworthy vessel indeed.  I sailed Zeavard in relentless 2-3 meter waves, 100-200NM offshore, for weeks on end. Much was learnt from this difficult voyage, with improvements being added to the updated version of the plans.
