When I ordered the carbon fiber cross tubes for my yellow 12′ trimaran, I assumed a modulus of about 16 million. And I speced the thickness accordingly. I just got the spec sheet from the manufacturer. 8.5 x 10 to the 7th. I checked with a scientist I know. That is 85 million. That is more than 5 times the modulus. Wow. They aren’t going anywhere.
I stumbled on this list that I made years ago. It still looks pretty good. I need to study it carefully for changes but again it looks pretty good.
SOURCES DECEMBER 28, 2012 KURT LEAVE A COMMENT EDIT A big mess of sources. I worked on a lot of these during the last few trips. I imagine this kind of being crowd sourced where people will add to this as it goes along. Some to be added anyway, but getting it out for what it is now. I see it doesn’t let me hot up the links. To get hot links, put sources in the search engine and load the one from years ago.
A sources list now is different than it was when I first did the Construction Manual. Presently the best way to locate boatbuilding products is to go to the manufacturers website, and from there find the vendors in your local area. This list is pretty much for North America. And it leans toward products that I have first or second-hand experience with. Builders elsewhere, get me your favorites and I will expand this.

That means I’ve owned my modified Hughes 63 built by Dencho in Long Beach for one-third of my life and half my adult life.
Man, time flies.
If I had the money and desire, I’d build almost the identical boat, but in carbon.
It’s about the maximum size cat you can singlehand or doublehand.
Yet we’ve also taken thousands and thousands people racing and sailing on her.
Speaking of 25, that’s the highest number of knots we’ve hit. Once under working sails, once under spinnaker.
One time south of Cedros we had her going 21 to 22 knots for an extended time, not straining at all. Waterline and the perfect point of sail were the magic ingredients, even when overloaded with crew, gear and Ha-Ha stuff.
Hi! I’m starting the build of a kurt hughes design day charter cat to be completed spring 2022 in southwest florida. it will be a cylinder molded wood composite build. I’d like to communicate with anyone else who is currently building, or has built a similar boat. i’m a professional boat builder, having built and worked on several of kurts designs.
couple of questions:
anybody have a suitable dagger board mold? or want to use mine when i’m done with it?
any good leads for sourcing rudder shafting?
if anyone needs uni or triax i have found somebody with a couple tons nearby (sarasota area). vectrix and very reasonably priced. let me know in the comments and i’ll post info.
At the end of 2018 I posted a power cat hull build. Upon completion of the two hulls, they were picked up by the owners and taken home to Maine to build the crossbeams and cockpit, as well as fit engines, electrical, etc. I’m happy to report that the resulting boat looks spectacular, and the owner/builders say that the shakedown cruise went well, with a smooth dry 20 knots. stock props.
