Resin infusion tutorial for carbon fibre parts by Easy Composites in the UK

I thought this video gave a good description of the infusion process in this case they used carbon but it would also work for fibreglass and core glass combinations with appropriate preparation.

Sailing World article on Ultime trimarans

James Boyd has penned an article on the latest generation of Ultime trimarans for Sailing World:


The current class of Ultime trimarans is bigger and more complex than ever, but a new breed of sailor knows how to handle them.

Since François Gabart won the Vendée Globe at age 29, he and his sponsor MACIF have graduated to the Ultime class, with a giant multihull launched last year purpose-built for singlehanded long-distance racing and record breaking. Gabart won last fall’s doublehanded Transat Jacques Vabre, and proved this was no fluke by winning the Transat bakerly singlehanded across the Atlantic, from England to New York, in May.

I'm back but more focused on trimaran news this time.

Hi all,
         I got a stack of nice emails commenting on me reactivating the news section.  I'm going to be more focused now on the trimaran side of things from now on because that's where I observe there is more of a gap in news.  I'm also going to keep an eye on the proa build and design side of things which once again is more of niche interest.  The catamaran news is very well covered by excellent commercial blogs like Catamaran Racing, News and Design so probably wont be putting up much content along those lines except on rare occasions.

Kurt Hughes 40' racing trimaran concept for Phil Stegall

Noted multihull ocean racer Phil Steggall was looking at one stage to build a 40' racing trimaran and commissioned Kurt Hughes to draw him a concept.  A more modern take on Kurt's F40 racing trimaran it enclosed a more commodious interior with more stowage while still keeping the racing edge. Construction was to be cored carbon with the platform to be square 40' x 40'.  Float foils were drawn as straight daggerboards but could be lifting foils if requested.
