Malihini (Shuttleworth 35 ft Catamaran) completes voyage from Hawaii to Oregon.

New owner/skipper Trent Sellens, and crew of 3, sailed Malihini from Nawiliwili Harbor, Kauai, Hawaii to Newport, Oregon in August of 2014. The 19 day passage was smooth and comfortable. Malihini will be undergoing modifications for easier cruising. Then off to the San Juan Islands and Canadian waters for a couple of seasons, and finally to the Sea of Cortez for the long term.

Charlie Magee writes - Thanks for the great boat, we all love it and wish we could afford to build 3 more.

New Shuttle 37 design for Geoffrey Strange in Seattle.

Shuttleworth Design has recently created a development of the highly successful Tektron 35. All the major components of the boat have been reviewed and redesigned as necessary to bring this concept fully up to date. A true open ocean voyager, with a long list of ocean crossings behind her sister ships, this will provide the ultimate combination of cruising and fun sailing.

2011 built Shuttle 31 for sale.

Mark and Susie Hicks have decided to sell their Shuttle 31 "Aleph". This is a rare opportunity to purchase one of these designs. For pricing, specification, and more... go to

Mark and Suze Hicks report in after their transatlantic voyage on their home built Shuttle 31 in January 2014.

I thought I'd let you know that Suze and I (with a friend crewing) have made it across the Atlantic in Aleph. We had a pretty gruelling crossing... After a perfect 'trade-wind' day at the start where we covered over 190 miles in 24 hours we rarely saw less than 25 knots of wind and for several days had 30+ with squalls in the 40s. We also enjoyed large confused seas as the easterly windswell from the strong trades mixed unpredictably with a pretty hefty swell from the north generated by the huge lows that pounded the UK over Christmas and NY. On occasion the cross swells were very large and we had to keep the speed down to stay safe which was frustrating. The asymmetric spinnaker I bought for the trip stayed in it's bag and instead a tiny storm jib I hoped to never deploy stayed up for almost half of the passage. I didn't even do any fishing!

The boat performed brilliantly as always, refusing to bury the bows even during some .. steep .. surfs and shipping very little water.

Incidentally we also encountered an unforecast F9 gale off the coast of Morocco in November where I towed warps and chain to slow us down. We'd found ourselves surfing under bare poles but after deploying the warps the boat sat quietly, making 4-5 knots for the most part and happy under the tiller pilot.

Anyway we're very, very much enjoying the Caribbean now and don't plan any long passages any time soon! We plan to stay here until April and then return to the UK by air, leaving the boat in Antigua.

John Shuttleworth and Superyacht Adastra appear in Mazda's new Advertising Campaign.

In August 2013 Mazda approached John Shuttleworth with the offer of appearing in their Challenger advertising campaign. The Mazda team felt that John's interest in fuel economy and "blank sheet of paper" approach to the design of the Adastra trimaran matched the philosophy of their new SKYACTIV TECHNOLOGY. Discussions with the Mazda production team revealed many similarities in the way both Shuttleworth Design and the Mazda engineers have challenged convention in the drive to create fuel efficient vehicles, whether on land or at sea.

John participated in creating advertisements for TV, cinema, web and print. The Shuttleworth designed Adastra trimaran uses one seventh of the fuel of a conventional superyacht of the same size, and can travel halfway around the world on one tank of fuel. The webisode shows the story of how John came to design the vessel with stunning shots of Adastra underway.

Joseph Oster has sold his Shuttle 35 fast cruising cat "Malahini".

  • Naval Architecture - Winner
  • Newcomer of the Year - Winner
  • Exterior Design and Styling - Judges' Commendation

Up against a field of 19 of the best superyachts in the world today, John Shuttleworth Yacht Designs was presented with the Naval Architecture - motor yachts award, at the Showboats Awards 2013 Ceremony at Monaco opera house.

Boat International Media noted that .....

The judges gave the nod to Adastra for her "clean sheet of paper approach" to problem-solving, and noted that her tank tests, as well as the physical evidence provided by designs of similar theory indicate "this yacht will have the best performance in the most sea states of all those presented".

John and Orion Shuttleworth have just returned from the prize giving ceremony in Istanbul where they proudly accepted the 'Judges’ Commendation for Most Innovative Design'.

"Adastra was very different. A remarkably low hull weight of 52 tonnes, a usable volume of 132 GT and a top speed of 23.2 knots, combined with her dynamic exterior shape and extremely low fuel burn of around 20 litres/hour at her economical 10.5 knot cruising speed, led the jury to award a judges’ commendation for extremely innovative design."

"Life's a Dream", Mark van Niekerk's Shuttle 47 cruising cat is for sale in Fort Lauderdale USA. ...SOLD January 2014...

For anyone interested in acquiring an excellent, well proven long distance Shuttleworth designed cruiser, this is a real opportunity.

Life's a Dream in the Indian ocean

Mark writes..... "My beloved "Life's A Dream" is currently moored in Fort Lauderdale and, as you are aware, up for sale. It was a gut-wrenching decision but I cannot bear to have her sitting in a marina waiting for me to take her out on the occasional week-end date! She deserves a full-time and committed relationship. My bond with her has endured since January 2007. We have completed a circumnavigation together. During that time I have logged over 30,000 miles and experienced many memorable passages in all sorts of weather and conditions. The average daily mileage for my circumnavigation was 180 miles. I am an extremely conservative skipper and I have no doubt that this could have been significantly increased if I had been pushing or racing.

Thanks John for all your inputs during construction and the subsequent 5 years of cruising, and mega-thanks for the vision and inspiration which culminated in my "dream" boat!"

Mark writes: "Just a quick one to let you know that we launched last week. The boat was spot on the design weight and true and high on her marks. We're very busy now getting all the remaining jobs finished - including outboard installation, we were towed to the marina - but hope to have our first sail in the next week. Work in the marina is constantly interrupted by people coming to admire the boat! Needless to say they are very surprised to hear it's home-baked..."

Mark van Niekerk has completed his around the world voyage aboard "Life's a Dream", his Shuttle 47 cruising cat.

"I am back in Cape Town with LAD and working hard at restoring her to her former glory and some more! As you can imagine there are a myriad of jobs to be done. Sadly I will be selling her as I just could not bear her sitting in the yacht basin wistfully watching the other blue-water cruisers arriving and leaving and having to suffer the ignominy of an occasional weekend sail. She will be all spruced up by the end of April and ready for another 30,000 miles of sailing." writes Mark. John Shuttleworth will be meeting Mark in Cape Town in mid April, and will return with an up to date report of the voyage.

David Warren and crew complete voyage from New Caledonia to Vancouver via Hawaii aboard "Dolphin Dancer", his Tektron 50 C cruiser/racer cat.

After nearly a year of planning, preparation, and then sailing, David Warren and crew have arrived in Vancouver. In his last email after arriving in the USA David says" So here we are in one piece after three weeks bobbing out there. We are all healthy and happy and DD is in top shape. The sea gods let us pass very nicely on this big voyage from New Caledonia. We head to Vancouver next couple of days and its back to work next week." For images and drawings of boat see: Images.

News in from Mark van Niekerk aboard "Life's a Dream", his Shuttle 47 cruising cat.

As Mark and crew near the end of his round the world voyage, Mark sends in this report about his trip across the Indian Ocean.

"Well it's hard to believe but here we are in Mauritius at the tail end of our trip. Next stop South Africa! The trip across the Indian was VERY interesting. The first leg to Cocos was light winds and frustrating calms with interspersed squalls.. The leg to Mauritius was the opposite - rarely below 30 knots with frequent 2 to 3 hours busters with winds peaking at 45 knots. We ran with a triple reefed main and a half-furled jib for most of the 2400 miles and completed the leg in 13 days. LAD behaved like a true thoroughbred. We had a murderous cross swell and most monos and all of the other Cats we spoke to had structural issues of one kind or the other. We came through unscathed although I did sail very conservatively".

Richard Oliver is providing structural design for the power 41 m Superyacht building in China.

Richard of ASTA (Applied Structural Analysis Ltd.) is now involved in all aspects of the structural design of the new Power 41m Superyacht building in China. Richard's involvement began with a review of the Finite Element analysis of the structure which has led on to him becoming fully involved in the project. He will be providing FE analysis and general engineering design and consultation to John Shuttleworth Yacht Designs on a number of projects that are under development.

Orion Shuttleworth sets up his own enterprise - "Orion Shuttleworth Design Ltd".

Orion Shuttleworth has spent the past 5 years working for Bernard Olesinski, a specialist in powerboat design, primarily concentrating on deck design and styling for the Princess Yachts. He has developed extensive skills in 3D modelling with Unigraphics NX, and brings a wealth of Big Boat design experience and understanding of LY2 and RINA regulations to offer as a service to our design office.

His expertise in 3D rendering can immediately be seen in his work on the new Power 41 meter Tri, currently building in China, in which he is playing a significant role in all aspects of the final stages of the design and preparing for classification under the Hong Kong flag authority.

Orion is also bringing his kiteboarding extpertise to developing a kite assist system for the 42 m Superyacht. Current systems for ships are very heavy and complex. Orion is working on a system that uses an inflatable kite which can be easily recovered from the water and will be launched off the deck of the boat using a lightweight carbon launch system. Progress will be reported on our site.

Orion will also be involved with many other aspects of all the projects we are currently working on.

Orion completed his first ocean voyage at the age of one, and has been sailing ever since then. Now an experienced cruising and racing skipper in his own right, Orion has a busy programme through the summer as Skipper aboard Bernard Olesinski's 40 ft yacht in the Jog series of offshore races, and Cowes week. Orion still finds time to enjoy his passion for kite boarding and windsurfing, complementing that with mountain biking when there is no wind.

  • Anto Marden of Hong Kong commissions John Shuttleworth to design a new 134 ft Power trimaran.

    P134-3D-aft-view-thumb.jpg 134 ft Power Trimaran.

    Click on thumbnail for larger image.

    The owner of "Mazinga", the 45 Ft sailing trimaran, see Images. and Race results, has been talking to John Shuttleworth for a number of years about a new open ocean cruising power tri. The basic cruising area would include Singapore, The Philippines. Hong Kong, and Indonesia. This has led to the development of a new 40 metre Power Trimaran.

    Based on the original concept developed by Nigel Irens in Ilan Voyager and Cable and wireless, this new boat is a departure from previous yachts of this type in that we have achieved comfortable accommodation for 10 guests and 4 permanent crew. This PDF file shows part of the layout. power-40m.pdf

    The boat will be powered by a single 1000 HP inboard diesel giving a top speed of 24 knots. Range will be 3000+ miles for long distance ocean voyaging, and around the world capability.

    A considerable amount of work has already been done on the design, including tank testing and the building of a 6 ft long radio controlled model with outrigger that can be raised and lowered independently by radio control. This has meant that we could test the performance of the boat in waves with varying outrigger height. By filming the boat in waves of varying height and wavelength we have been able to study the motion in detail. We could then correlate this with the tank test results to find the optimum position of the outrigger in relation to the main hull. We have been able to demonstrate that outrigger immersion has a very significant effect on roll damping in this type of vessel.

  • News in from aboard the Shuttleworth 47 ft cruising cat "Life's a Dream".

    Owner Mark Van Niekerk comments after a trouble free voyage from Cape Town to Trinidad. First 5000 miles of ocean sailing completed. "The performance really exceeded my expectations. You saw the mileages and we never pushed. Particularly memorable was the last 5 days when we were on slightly more than a beam reach with between 13 to 18 knots and , with 2 reefs in the main and the working jib we were achieving 7 to 8 knots through the water and perfectly balanced - I would switch off the auto pilot for 20 minutes at a time without touching the wheel. Since I have not crossed an ocean before on a cat maybe my expectations were low! However, I have had a number of cat owners on my boat and we have anecdotally shared experiences and none were as fast as LAD and most experienced discomfort - particularly water slapping on the bridge deck.

    Comfort is unbelievable. I truly marvel at how gently she rides the waves and swell. It would be fairly rough with 20 to 30 knots of wind and we would be sitting at the saloon table eating soup out of a bowl with our wine glasses scarcely showing any sign of movement.

    I could say more and would be happy to address particular areas if you would like.

    Kind Regards,

    Kenmore, lying second on elapsed time and on handicap, was set to move into first place as race leader Pete Goss was forced to put into port for repairs. This report from The Daily Sail/...

      Kenmore dismasts.. Disaster off the Hebrides in Round Britain and Ireland Race At approximately 1000 this morning Nick Bubb and Pete Cumming's trimaran Kenmore lost her rig. Roughly 30 nm south of St. Kilda, sailing under reefed jib and reefed mainsail, in moderate seas the duo tacked onto the layline for St.Kilda. There was loud bang and the rigging terminal for the lower diagonal shroud pulled out of the mast leaving the rig unsupported. The rig broke two metres from the base and fell over board. Fortunately Nick and Pete have been able to retrieve all parts of the broken mast, the rigging and the sails. Using the boom they have erected a jury rig and they are hoping to sail to mainland Scotland without assistance. Neither crewman were harmed in the incident and there is minimal damage to the boat. Understandably, they are very disappointed as before the incident they had overtaken Alacrity and with Pete Goss and Paul Larsen having to make a pit stop for some repairs, the pole position was up for grabs.

  • >Meridian (ex Caledonia) now renamed Kenmore has been entered into the Shetland Around Britain and Ireland two handed race, starting on in Plymouth on the 11th June 2006.
    Nick and Pete

    Caledonia was built by Rod Stuart in 1987. Rod sailed her to record win in class 6 of the Single handed Transatlantic Race in 1988, (see Race results). She was then renamed Meridian and, sailed by Roger Barber, she led the previous race against much larger boats until she was dismasted off Scotland. ( See earlier news item on this page.) Now renamed Kenmore, and extensively refitted, she is still considered to be a potential winner in the Shetland around Britain and Ireland race. Nick Bubb and Pete Cumming will co-skipper the boat this time, and have fitted Kenmore with a new 15 metre Carbon Mast.

    Zazen-sailing-thumb.jpg click on thumbnail for larger picture.

    Gary Pearce and his family have arrived in Australia. After an amazing trip which Alix has written up in Mutihulls Magazine, Gary , Jane, Alix and Lorin have arrived in Coffs Harbour. Gary sends this report...

    "Just to let you all know that Zazen has safely made the full Pacific crossing arriving in Coffs Harbour on Monday Oct 26th at lunchtime local time (midnight on Sunday evening for you UK based chaps) Full newsletter for the final few months will follow shortly but let it be said that the Pacific did not let us escape easily. The final 24 hours before we arrived we had a full gale out at sea with sustained wind over 30k for 8 hours and over 40 for 2 and a max reading of 49.7! Breaking seas with 9m waves. Zazen performed very well with the sea drogue out and the storm jib but it has taken the crew and skipper a few days for nerves to return to normal! Luckily the price and availability of local beer here helped the nerves. We will wait here for the right weather to make the final 240nm to Sydney - a coastal passage.

    all the best,

    Jane and Gary, Alix and Lorin"

    Gary Pearce and his family left England in August last year (2002) and sailed down to Spain with John Shuttleworth as crew. See "Biscay trip photos. They then headed for the Caribbean taking part in the Atlantic Rally for Cruisers (the ARC) on the way. After Christmas in the Islands, they headed for Panama, and then on to the Galapagos. From there they have sailed to the Marquesas, and on towards Tonga, where they reported that all was well and the they were making good progress across the Pacific. Position as of 26th August, 17 39 S, 171 40 W. Gary said "We have been having better weather and times since the Atlantic and the Pacific is a zillion times better than the Caribbean ! Perfect conditions for this boat in fact."

The sterns of the boat were modified using information gained from the tank testing on the Powershuttle 40. John Shuttleworth writes, "The boat performed exceptionally well. She will do a comfortable 14 knots at 80% throttle. Sailing performance is only slightly compromised and the high speed end seems to be as good as before. The new sterns are a success and the boat trims very flat at high speed under power. This keeps the waterline long and the drag down." An article will follow soon.

    The Fossailiing team of 12 sixteen to seventeen year old students at a Waldorf School in Switzerland have launched the two Shuttle 31 Catamarans that they have been building for the past two years. They have motored down the Rhine and sailed down the coast to Calais in France, where John Shuttleworth went to meet them and sail to Cowes as part of extended sailing trials.

    After sailing from Calais to Cowes, John Shuttleworth spent three days sailing the two boats in the Solent in a variety of conditions. The boats are well built and look fantastic. With the wood epoxy strip planking left as a feature on the interior, they have a lovely wooden "feel" inside. Both boats sport the racing rig with Gougeon wing masts. "We chose Gougeon because they were the only masts we could build ourselves" said Thomas Wolf.

    John Shuttleworth writes "The Fossailing team have clearly demonstrated that the Shuttle 31 is a good boat for amateurs to build. They chose to use my design for strip planked Western Red Cedar with glass fibre on both sides and although I predicted that they would add about 230 Kgs to the weight of the boat over a foam sandwich version, they are sure that they have added less weight by being very careful in the laminating process. Certainly the boats float on their marks and perform very well and we achieved 8 knots to windward tacking through 85 degrees. As usual easily outsailing any monohulls that we came across in the Solent. I have enjoyed the experience of sailing with this enthusiastic group of young people and I would like to take the opportunity to congratulate them all on a fine achievement. The boats look good, and I am sure they will have many years of enjoyable and fun sailing on them."

    The teams sailed the two boats in the Solent near Cowes for a few weeks to fully prepare themselves for the trip to Elba. They sailed across the English channel, through the Bay of Biscay, down the Spanish and Portuguese coasts, and into the Mediterranean. They arrived safely in Elba on September the 23rd, having covered 3500 miles. A very successful end to an amazing project. Read more about the project at

  • John Shuttleworth joined Gary Pearce and his family on their first leg south en route to Australia aboard "Zazen".

    John Shuttleworth set sail two weeks ago aboard "Zazen" to sail from Falmouth in England to north west Spain across the Bay of Biscay. He had been invited to help Gary and Jane Pearce and their two Children Alix and Lorin, to get started on their Voyage to Australia. Photos of the trip, and some new ones of the Shuttle 40 "Zazen" can be seen at "Biscay trip photos."

    Gary Pearce bought Zazen from John Shuttleworth two years ago, and has spent the time finishing the interior and rigging the boat. Although there were some details of the fit out to complete, Gary decided to head south to get clear of the winter weather in the Bay of Biscay.

    John Shuttleworth writes "We set off with a force 4 to 6 NW winds forecast, which was perfect for us. Needless to say the Wind was WSW F2 to 3 for the first 12 hours, then flat calm with fog, followed by NE F4 to 6 for the last 12 hours.

    This meant that we motored for about 50 hours, using the radar to avoid the huge ships that travel up and down that route, but when the wind blew we had a fabulous sail. The boat performed excellently and we still managed a comfortable 3 days for the 500 mile trip.

    The Shuttle 40 proved to be ideal for long distance family cruising, with lots of space for people to get on with whatever they were doing, without feeling at all crowded. The autopilot worked well so we rarely had to steer, and even tacking could be done from below by dialling in a tack on the autopilot, and the boat would just tack effortlessly. This is one of the great advantages of the self tacking jib. No sheets to haul in, and no flogging lines to hurt the crew. The children were busy during the day with reading, painting, and whale and dolphin watching."

    John left the boat in Muros after a most enjoyable few days in the Spanish Rias, and he wishes Gary and his crew fair winds as they join the annual Yacht migration south toward the Caribbean.

  • Meridian dismasted after severe gales in the Round Britain and Ireland race.

    Meridian the 30 ft Shuttleworth Trimaran was dismasted on the thrid leg of the Round Britain and Ireland race. A severe force 10 storm had bunched up the fleet as they waited to depart for Lerwick in the Shetlands. The tough decision facing all the skippers was how soon to leave, as the storm abated. The dimasting occurred when they crash gybed in strong winds while pushing to maintain their lead over the 40 ft Trimaran "Mollymawk" which eventually went on to win the race. The crew are safe, and Meridian has motored into Lerwick but is out of the race. Congratulations to Roger Barber and his crew for their amazing first two legs. We are looking forward to seeing him back on the racing circuit soon. And congratulations to Ross Hobson on a fine and well deserved overall win.

Skipper Roger Barber was able to maintain a one hour 24 minute lead over his closest rival "Mollymawk", a 40ft Nick Baily designed Trimaran.

    Meridian has an 18 hours and 23 minute lead over the next boat in her class and is putting in an astonishing performance for a boat in class 4.

  • Meridian the Shuttleworth 30 ft racing trimaran that won the around the island race in 2000 wins the first leg of the two handed around Britain and Ireland race.

    13 boats have been forced to retire from the total entry of 38 on the first stage to Cork, Ireland of the Round Britain and Ireland Race. Strong winds have pounded the fleet, with dismastings, broken daggerboards and crew health problems. Among those who have been forced to retire are 'Spirit of England', skippered by Sir Robin Knox Johnston, and the all women team on QII, Becky Walford and Mary Faulk

    The first finishers in Cork last night, and in the early hours of this morning were at 23:00 hours on the 10 June the 30ft trimaran 'Meridian', followed three hours later by the 40ft trimaran 'Molly Mawk', and third in was 'Roaring Fourty', the class 3 winner in 1998, who have since retired from the race.

  • After 2 years of hard work the Foss sailing team of young people have Launched their first Shuttle 31

    Two strip planked Western Red cedar versions of the Shuttle 31 have been built by 12 students at a Waldorf School in in Switzerland.

    Teacher and team leader Thomas Wolf writes: Our shipbuilding is a highschool project with twelve students. We will finish in May 2002. Then we will make a journey over Rhein, Main, Donau to the Mediterranian. The students write "We are twelve students at the age of 16-17 years. We visit a Waldorfschool in Muttenz, Baselland. Our project is to build two Shuttle 31 during two years. Two afternoons per week we work at the boats. While our schoolmates attend special courses like working on a farm we will solely concentrate on building the boats. Also during the holidays we will sacrifice some weeks for the project."

    Progress report as of 12th June 2002 is as follows: "We launched the first Shutle 31 in front of a large crowd with a few items still to complete. The boat slips very easily through the water, and we are looking forward to reaching Cowes in southern England with both boats around the last week of June." Part of the project is to make a web site. This can be seen at

With a clean bottom and the sails setting well, she easily exceeded wind speed. Acceleratiing with the slightest puff. The only mishap was breaking a spinnaker halyard in 7 to 8 knots of wind doing 12 knots. Dyneema is vulnerable in a jammer, and the plan is to use a cleat on the mast in future. Gary is working up to take the boat up to do the 3 peaks race, and the voyage up to Scotland should be a good shake down cruise. More on that will follow. look at Zazen sailing

  • Advantage 44 "Tigger" makes good time from the Scilly Isles to Falmouth.

    Peter and Toni Nice have been on their first long trip since spending a year fitting out their Advantage 44 from Burkhard Bader Catamarans.

    Peter writes "Hi John, just thought we would pass on some comments. We took "Tigger" on a 3 week cruise to the West country our first real trip with sailing gear sorted and a clean bottom.

    To give you a flavour we pulled the anchor up in Hugh Town, St Mary's (Isles of Scilly) at about 2pm and with slight seas and a North wind we set off for Falmouth 75nms away. We were sat down in the pub in Falmouth drinking our first pint at 10pm.

    For the stretch to Wolf Rock we were reaching at an effortless 16 - 17 knots with a maximum speed of 19.2 Knots, even the dolphins got tired. But it also included a long beat in light winds into Falmouth itself.

    We must be doing something right although there is still a lot more luck than judgement."

  • First Tek35 in England.

    Hull #3 from Tek Composites in Canada was delivered to Southampton on the 18th of August 2001. Richard Stilgoe ( the owner) specified dark blue hulls with white decks, and red boot top. This striking colour scheme looks very good, and the boat is an eye catcher as she lies at Saxon Wharf, Southampton, waiting for Richard to sail her to Salcombe at the end of September, where she will be based.

    John Shuttleworth and his wife spent an enjoyable day sailing with Richard, Checking her out on all points of sail and testing the sail wardrobe. John comments "The boat tacks thorough 80 degrees, just outpointing a similar sized monohull in the Solent. Eugene Tekatch has provided the boat with a comprehensive wardrobe, and all the sails appear to be very well cut. I had a chance to test the first Tek35 with the sailmaker on board, and our discussion has definitely been fed back into the cutting of these sails."

    Richard is very pleased with the boat, and some of the ideas he incorporated into his boat, are now being included in further production versions. More information on the Tek 35 and Tek Composites is available at

    Zeepoes the Shuttleworth 63 has been sold and refitted for another around the world voyage. After successfully circumnavigating with a crew, his wife and small child, David Holgate sold Samcat (ex Zeepoes) to Steve and Maria Ferguson. They have refitted the boat and added a fixed bimini over the cockpit. They set off last week for an extended around the world voyage with their 3 children. They intend to sail through the Mediterranean this summer.

    Steve had Zeepoes surveyed after her fist around the world trip, and she came through with flying colours with no structural problems whatsoever. The Surveyor said "It would be inconsistent to find delamination on a boat as well built and designed as this one."

    Owner number two is settling in to the cruising life with his family in the Bahamas. Jeff writes" John, just dropping a line to tell you that we are enjoying the boat very much. We are in the Bahamas, hanging in Nassau for the moment before waiting for more settled weather to head on. Now that I am in my 30s, I have finally learned with the help of my kids, to slow down and do more hanging and less sailing from place to place. We actually had the drifter out the other day and found ourselves close reaching at about 5 knots in about 6-7 knots of wind. The design is great, and I expect that the size is a good compromise between big enough to be comfortable in everything and small enough to be a pleasure to handle in 99% of the stuff you sail in." Jeff adds: Did I mention that we won the Georgetown cruising regatta harbor race? on an 8 mile race we had a 7 minute margin on the next boat. Other cats were a lagoon 42 and a catana 401 ( and some assorted geminis and other non-competition). We took all the canvas and 800 lbs of stores off, and ran with empty water and near empty fuel tanks. At the awards ceremony we were referred to as "that rocketship Socia".

    No.3 nears completion. The third Tek35 production boat. This one with striking dark blue hulls is bound for England where she will be moored in Salcombe. The boat will be sailed down to New York and then shipped to England in July.

  • Comment on First T35

    The first production Tektron 35 "Cats Away" had just been launched and the final preparations for sailing were being made as I arrived at Royal Hamilton Yacht Club. She was floating well up on her marks with the transom clear of the water. The interior was basically fitted out but none of the cushions were in and some water tanks and electrics still needed to connected up.

    We sailed in winds that we estimated were up to about 11 knots. Most of the time we sailed at close to wind speed with a maximum speed under Main and blade jib of 9.5 knots. There is a light genoa to be added to the sailing wardrobe like the one on the Shuttle 31

    This large genoa will bring the boat speed up to equal wind speed in winds up to 15 knots apparent.

    The boat feels light and responsive. Any change in wind speed results in immediate acceleration. Sailing at close to wind speed means that one knot increase in wind speed results in nearly two knots increase in apparent wind.

    The finish on the outside of the Tektron 35 is excellent. The second one coming off the production line looks very striking with dark blue hulls. Eugene has incorporated many interesting ideas in the deck layout, and engine installation, which are all improvements as a result of sailing the earlier non production versions. The winch positions and layout of the lines all coming back to the cockpit with stoppers near the helmsman, works very well.

    The steering was light and very responsive. The boat tacks on a dime. The only task we had when tacking was to push the jib traveller down by hand in the light winds we had on the lake.

    The additional cuddies over the entrances also look good, and provide good access to the hulls. The dodger that covers the central seating in the cockpit is a good compromise. We were able to sail with this off and still retain the feel of an open bridgedeck boat - which I like. Yet there will be good shelter for the cockpit when in colder regions.

    Inside, all the interior is built in modules in molds, then dropped in to the hull. At this stage bulkheads have been structurally glassed in already, therefore all that remains is to bond these modules in, and then finish to the joint of the mold with headlining.

    7 boats are now on order, and Eugene Tekatch is building them in groups of three. With 15 men working hard, the shop is a busy place.

    This is an exciting venture, and I am pleased that Eugene has taken up the challenge of producing a genuinely modern, fast and sophisticated Multihull with good accommodation. I think this boat will be in a class of it's own for many years to come.

  • Shockwave

    The 34ft Shockwave racing trimaran has been chartered for the season by Peter Bryant. A full racing campaign is planned and a development program will be carried out with a view to designing a new 40 ft racer. Strain gauges will be fitted to the hulls, cross beams, running rigging and standing rigging. All the data will be fed into a computer concurrently. this will give us vital information as to how the boat is actually stressed in a seaway and at what rate of change. I will write more as we do the testing.

  • Burkhard Bader has just launched a new Advantage 44 named "Maudy". Built for chartering, the boat is fitted out with a considerable amount of gear. Side View, Aft View, Overall view

  • Photos have arrived of the First Shuttle 28 to be launched. She was built in Finland of Strip planked Cedar with ply bulkheads and structure. This beautifully finished boat motored comfortably at 7 knots using 1 litre of fuel hour, on her way to be completed and rigged. Jukka Henttu would be interested in building more boats to this design. Afloat, Flying 2 hulls Almost in the water, Build shot, Motoring off for completion.

  • Using the moulds for the Advantage 44 Burkhard Bader has started an open bridgedeck version. This boat will be very reminiscent of the Original Spectrum 42, the cat that started this new development of open bridgedeck cats with large accommodation in the hulls. This was achieved with the flare in the hulls. A concept that is now well established in all Shuttleworth Cruising cats.In build, side by side comparison

  • The latest 52 footer drawings are in. and she looks pretty smart ! The rumour mill suggests the budget might even run to a high tech build in pre-preg ! There are 6 drawings in the images section, but for a taste click here

  • Its a busy time in Canada. Must be the long nights. These photos just in of an impressive Ocean Cheetah 37 in build. Looks like it will be pretty impressive. Side View   Further Side View   Cockpit  

  • The other new 52 footer looks like a nice blend of comfort and speed. Accomodation 1 (52k), Accomodation 2 (128k), Sailplan 1 (60k), Sailplan2 (52k), Deck 1 (60k), Deck2 (136k)
