New Tony Grainger designed carbon TR36 trimaran ready to launch

The class leader of the new Grainger TR36 design is ready for launch.  Built by the team at Current Marine in South Africa who have done a beautiful job.  This boat is all carbon and it appears they have all tooling ready for another should someone else like to take the plunge.

From the owner:

Freshly Squeezed, a full carbon TR36 built by Current Marine South Africa , gets wet for the 1st time tomorrow morning. All being well and with the Knysna heads permitting, we will stretch her legs next week. Ultimately she will be sailed in UK waters.

Shuttleworth 39' offshore racing trimaran launches

Andrew has launched his Shuttleworth 39' racing trimaran in the UK.  You can read more on the design at the Shuttleworth designs website.  The team managed to get the boat to it's target weight which is no mean feat for a racing trimaran design.  The boat has a reasonable interior for a racing trimaran.  Future plans are to race in the Round Britain and Ireland yacht race and extensive shakedown to get the boat optimally tuned.

Another beautiful design by Jan Andersen the Black Marlin this is intended as a more cruisy version of the Barracuda which still offers very good performance.  The plans support building in timber composite strip plank or carbon/core.

Tony Grainger TR36 trimaran

Tony Grainger has added a new design to his current trimaran portfolio.  The TR36 trimaran is aimed at a more economical solution to performance trimaran cruising while still offering workable payload and cruising comfort.  As the length of the boat decreases the cost of build tracks down in accordance.  It will be available as plans/pre cut duflex kit or to fully constructed sail away stage by one of their nominated builders.

GF42 foil assist trimaran launched, videos of the boat in action

Following up on the GF42 trimaran design that was a collaboration between Greg Lynn and Fred Courouble.  The boat has been launched and after some initial problems (the mast dropped and broke when initial installation was attempted) has been out tearing up the ocean.  Future plans involve cruising the coast at speed and competing in the various events that are now welcoming multihulls on the West Coast scene.

Corsair Pulse 600 trimaran update # 15

From the following entry by Corsair marine:

http://sail.corsairmarine.com/development-update-15-on-the-pulse-600

Following some great sailing last weekend on hull 3, it really feels like this Pulse is getting its rhythm!

We had decent wind conditions with 12-15 kts of breeze in semi-sheltered waters and the boat just felt fantastic. We were running without the bowsprit option (coming soon) and had some great screacher runs where the boat really got up and started to sing. As if the blood wasn’t pumping enough, skimming along at around 13-16 kts with the kite up, it was time to test the rudder balance. It felt so controlled that taking your hand off the tiller extension and letting the boat go was never an issue. So there we were, on a brand new boat, with all hands off. A great feeling!

Corsair Pulse 600, development update #14 new folding system and refinements in place

From the following press release by Corsair Marine:

http://sail.corsairmarine.com/development-update-14?mkt_tok=3RkMMJWWfF9wsRonuqnIZKXonjHpfsX56esrW6SzlMI%2F0ER3fOvrPUfGjI4DTcdgI%2BSLDwEYGJlv6SgFTLLCMbR4w7gJWxI%3D

After the successful test sail on the water testing in Nha Trang last month (update #13 http://sail.corsairmarine.com/sailing-review-on-the-pulse-600 ) we have been focussing on some modifications to really take the boat to the next level, and ready for the real product launch. Hull #2 is heading out to Brisbane, Australia next week where it is to be demo sailed and then exhibited at The Sanctuary Cove International Boat Show. We also have Hull #3 due to hit the water here in Vietnam as we have some local testing and demonstration sailing to be done!

So what have we achieved?

Folding System
The biggest modification is the folding system. We have moved away from the soft lower strut system which was simply too hard to use and in reality didn’t offer the rigidity we required for this product. We have now replaced this with a new anodised aluminium folding system. Similar in concept to our larger Corsair models however the new folding system uses a solid “V-shaped” lower strut on all four beams.

The complexity of the geometry involved is particularly high as the buoyancy of the float will dictate how much you can push the float through the water when you are folding. Not easy to setup however after testing the boat on the water, we struck off another milestone with this project by confirming that it is now an easy single person job to fold both on the water and on the hard. Another important feature to mention here is that the capshroud does not need adjustment when folding the boat. Likewise, the trampolines require no adjustment when folding as they self-tension when the folding system is opened out.

Searail Trimarans discuss the design objectives of their folding system

From the following press release on Searail Trimarans website:

http://www.searail19.com/2015/03/the-searail-19s-revolutionary-folding.html

Weighing in at less than 20 pounds

The SR-19’s revolutionary folding system is just one of many engineering innovations incorporated into this Nigel Irens' design. The folding system allows the boat to be folded, unfolded, or the entire beams/float system to be de-mounted in literally seconds. The folding system is a key structural component while remaining extremely lightweight and completely hidden under sail. An evaluation of an on-the-water folding system was found to have negative effects on a trimaran of this size. Using the latest Naval Design and Engineering 3D Modeling software, we identified several safety and performance concerns with the traditional on the water folding strut system.

Sailing review of the Corsair Pulse 600 trimaran by Richard Ward CEO of Corsair Marine International

From the following update on the Corsair Marine website:

 

http://sail.corsairmarine.com/sailing-review-on-the-pulse-600#

 

Nha Trang, Vietnam has been rightly claimed as one of the most beautiful beaches in the world, and a wonderful sailing playground. Especially so in February, when there is almost a guarantee for no rain and reliable NE winds. It was the perfect location to hand over our latest launched Seawind 1160 Lite to an Australian customer and to test sail the incredibly exciting new model for Corsair, the Pulse 600.

Awaiting us as we arrived to Nha Trang, the just launched Pulse 600 - looking amazing on the water - was crying out to us to be sailed. In the late afternoon on the first day, we had perfect sunshine and the winds still at 16 to 20 knots and gusting higher occasionally. Zam (the Production Manager for Corsair Marine), Kerry (my partner), and myself took it out for a short test spin before our photo shoot the following day.
