Kurt Hughes, updates to Daysailor 23' trimaran design

From Kurt's Multihull design blog:

http://multihullblog.com/2017/02/23-trimaran-update/

I finally got the first run of modeling the updated 23 daysail trimaran. Version B will have ama rudders and the even hotter version C will have foils. It is a developed plywood/epoxy unit with core vacuum bagged onto the flat surfaces needing that. And carbon fiber where it helps. At around 360 kg lightship weight, it can be built for around $5000 us in construction materials. The connecting beams should be carbon mast sections. The camper version comes next.

Chris White designed Discovery 21 trimaran

The crew over at Aquidneck Custom Boat Builders/Performance Multihulls have been constructing an updated version of Chris White's original Discovery 20 design.  The new trimaran will be available in either a kit version for the owner to assemble or a full constructed sailaway package.  It features a folding mechanism, spacious cockpit and updated rig.  Chris has revisited the platform design and powered it up with larger floats.

Some photos of the platform of the first boat out of the molds have been posted along with a flyer with features and preliminary pricing.

Multi23 Mk2 trimaran updated model lighter in weight and offers more features

Phillipe Mallajac of Torpen International Boats the manufacturers of the Multi23 trimaran have forwarded the following press release which covers the updated version the Multi23 Mk2:

For those who still don’t know yet about the Multi 23 trimaran,
she is a kind small amazing replica of the famous Maxi Trimarans “Orma 60”, but only 6,72 m long, both designed by the renowned naval architects firm Van Peteghem Lauriot Prévost (VPLP) and built by the French shipyard “Torpen International Boats” up to more than 90 boats sailing worldwide, and… she is about to make her revolution! The shipyard announced the launching of the Multi23 MKII version, whom received a lot of improvements.

This new version is still built using infusion technology and high quality materials (Epoxy, carbon, vinyl ester, PVC foam core, …), which make her very light, but she receive now more reinforcements in carbon such as the beams 80% carbon and wherever it was necessary.
This new version of Multi 23 is more stiff, more responsive and faster than the previous one, she starts flying even in the slightest breeze!

Standard Multi 23 is still delivered with completely sufficient rigging of 3 sails (Mainsail with 2 reefs, Self Tacking Jib, Gennaker).
The Optimization of rudder system (100% carbon now) and the retractable centreboard, particularly by increasing strong carbon structural reinforcements, gives them reliability to withstand the forces generated by high speeds over 20 knots allowed by the design of the platform.
Among the new options, some are nicely surprising, such as:
Mast travelers allow effortless hoisting of the mainsail and add safety by controlling dowsing, even on the run, in case of reefing or simply when approaching to the mooring place. Raising up the Main becomes a child’s play!
Superb 100% Carbon Bowsprit for those requesting the asymmetric Spinnaker.

All on board is high quality equipment: the hardwares are signed “Karver Systems”, including Jib & Gennaker easy furling systems and a very well ingenious Single Jib sheet, crossing through the main beam and  mounted on a 180° swivel cleat tower. We appreciate the optimization of the operating commands wherever you are on the platform, the solo sailors will be really delighted!

In few words: Easy to handle, Speed, Stability and Safety are key points for this new Multi23, she has the talented skills to combine high performances as a sport-boat for racing, but also a user-friendly day-boat for family sailing or hiking…
Pure and unimaginable sailing sensations, we love it!

Weta Trimarans, short video details updates on 2015 model

A short video by Weta Trimarans showing the improvements made in the 2015 model.  It's just a general tidy up of the platform smoothing things out and cleaning up details the one design rule remains unchanged and the platform, sail area etc is the same.

Video from Stephen Walker of Ahoy Boats showing delivery of Catri24 hydrofoil trimaran from Latvia to England

And the description from the video is below:

Sailing a fast hydrofoil trimaran is easy if it is designed well, like this CATRI. Checkout http://ahoy-boats.net/why-trimarans-a... to learn more about Why Trimarans are so FAST and why they are more practical than hydrofoiling catamarans. In 2005 Steve Walker, founder of Ahoy-Boats, http://www.ahoy-boats.co.uk, delivered TARDIS, so named because she was amazingly spacious inside (5 berths!) and she looked like a space ship from the future, all the way from Ventspils in Latvia to England via, Gotland, through a full gale to Öland, onto the beautiful island of Hanö, then through fog to Ystad (home of fictional character Wallander), the tiny fishing port of Skåre hamn in Sweden on mid-summer's eve, then to Gedser in Denmark, Kiel, (during Kiel week), through the canal to Brunsbüttel and down the Elbe to Cuxhaven in Germany, then along the Friesland coast to Nordeney, Vlieland, (see blog entries for June 2005 here: http://www.ahoy-boats.info/archives/s...) then the island of Texel, the seaside resort of Scheveningen in the Netherlands whereafter another gale was encountered and shelter sought at Stellendam before the final two legs to Ostend and across the English Channel to Dover (see blog entries for July 2005 here: http://www.ahoy-boats.info/archives/s...). In 2014 you will again be able to buy a CATRI hydrofoiling trimaran! However, this time is will be 100% instead of 90% foiling and will be available as a 25ft or 28ft boat. The CATRI foiling trimaran concept is much safer than the crazy America's Cup AC72 catamarans, which were not designed for real sailors who go to sea but for publicity. The new CATRI trimarans will be available with automatic sheet release systems so as to prevent capsize and the foils support the boat in such a way as to prevent pitchpole,http://www.ahoy-boats.info/Safety-Sta..., rather than to cause it. Afterwards TARDIS was anchored overnight at Dungeness, sailed past the Seven Sisters and Brighton to Littlehampton and thence through the Solent & past Bournemouth to Poole for the Goathorn Regatta. She is now in the USA near Chesapeake Bay.

Farrier F-33 trimaran update, hull #1 nearly complete Ian Farrier visits Multihulls Direct in the Phillipines

From the following article on F-boat.com by Ian Farrier of Farrier Marine:

http://www.f-boat.com/pages/News4/F-33Update.html

I managed to spend a day in the Philippines last week to inspect the latest F-33s as being built by Multihulls Direct at the Clark Field Freeport Zone. It was difficult to break away from work on the production F-22, but the all new 2013 F-33 has been proceeding well, and a visit to check on progress was well overdue.

Overall I was very pleased with how it is all going, with company owner Mike Mallory and his crew of 27 doing an excellent job. They have now moved into a new much larger factory, and building is to a very high standard. Some photos taken while there include:

Kurt Hughes designed CHS X-19 trimaran, small trimarans blog audio interview with builder John Lange of Charlotte Harbor Sails

From the excellent smalltrimarans blog:

http://smalltrimarans.com/blog/?p=10308

How about an audio interview about the CHS X19 Sport Trimaran — a new sailboat that is about to be built by Charlotte Harbor Sails in Florida? Charlotte Harbor’s proprietor, John Lange, was specifically looking for a boat with its features.
John was able to find just what he was looking for in this model, which is a design by Kurt Hughes. (My short audio interview with John is found below).

Catri 25 trimaran, new webpage launched

The Catri trimaran which has been out of production since the previous company that was producing the boat folded.  It is now set to be re released by the new Catri group, this webpage covers the revamped and updated Catri 25.  These are very interesting trimarans having lifting foils and "t" rudders for stability and relatively low float volumes.

Kurt Hughes 75' cruising trimaran design

Kurt Hughes still has an interest in designing large trimarans for cruising and the results are certainly impressive.  He has quite a few world cruising trimarans under his belt and the reports from the field on their motion and comfort are very positive.  This is an update from his facebook page on one of his current projects a 75' cruising trimaran.

Kurt Hughes Trikala 19 trimaran design updated and intended to go into production in Asia

Kurt Hughes has released a render of his updated Trikala 19 trimaran that is apparently going to go into production in Asia.

http://multihulldesigns.com/designs_stock/daysail/19_tri.htm

It uses the "monoslip connectives" illustrated on the Trikala 19 page it looks like a good and simple system for a small trimaran. The waterstays come tight as the beam slides out for sailing but you can move the boat around by motor with the floats retracted. The benefits seem to be that you can get the boat narrow for a marina berth without getting growth on or having to antifoul the top of the floats as on a f-boat or occupy extra berth length like a dragonfly. There would be a restriction on overall beam though I imagine due to the length of beam coming through the boat and out the other side when folded but with the width of the main hull deck should not be much of a problem. The diagrams I've seen show just the end of the beam in the tube near the gunnel when deployed at full width as there is not much need for "bury" in the main hull gunwhale thanks to the waterstays taking the bulk of the load.

Here are Kurt's notes on the updated design and the differences to the original. Interesting to see more trimarans under construction in asia the TC627 is the most recent I know of. I'll be curious to see who is taking on the construction of this boat and whether they bought the original molds and decided to give it a bit of a facelift? Good to see more options in the production small trimaran market.

http://multihullblog.com/2013/02/trikala-19-trimaran-update/

"The Trikala 19 trimaran has been updated. The original design had a main hull and deck as 2 pieces. The update is a single piece, (well 2 halves) and looks more rounded. It also has X bows to increase speed in waves. It will be built in Asia. It can be made ready to trailer in a few minutes. It can stay on the water in the “in position” indefinitely. I’m sure it will cost less than the same size folder."
