I got a commission to design a niche charter cat for Miami. The customer has built boats before but knows nothing about cats nor naval architecture. With the outboards they insisted on, the adjustable swim platform and its mechanism, the Cg is a full four feet aft of Cb. I am having a hard time convincing the builder this is bad. i may have to walk away from this one. Foam/glass.
This 79′ day charter power cat is being designed for a group in California. They have been delightful to work with. Good project. Foam/glass.
I just got pictures of a CM built Tomcat 30 trimaran with updated amas. It looks hot. It was built in the early 90s as I recall.
I just got this picture of the 3rd or 4th design that I ever did. Back in the hand drawing days. Cylinder molded plywood/epoxy. 1986 I think it was. It still looks really good to me. 37 feet.
Peter Mannerstråle sailing one of my 42 foot cats out of Sweden posted what I think is one of the coolest pictures that I have seen in a long time. All is right with the world.
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.
Painted with Awlgrip clearcoat.
The Meermark 17, a Kurt Hughes designed 17 footer that provides, easy, safe, fun, fast and affordable sailing to everyone. #sailing #sailingforeveryone #sailability.
On the spur of the moment I decided to go to White Salmon to pick up the carbon fiber tubes I had made for the little yellow trimaran. Innovative Composites Engineering.
I also got a tour of the place. Amazing. Stuck in the woods outside of White Salmon. Space X is their biggest customer. They have giant presses to compact the laminate even more than bagging. I wasn’t allowed to take any pictures inside the building. And also warned not to touch anything.
They consulted on Oracle. Hence in the boneyard.

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.

I just had a meeting with a rep from TriStar Plastics Corp. This is the
plastics equivalent of a steel service center. They stock plastic, machine
plastic and will provide technical advice on what is best for a particular
application. Interestingly they make a wide variety of bearings which would
seem ideal for rudders etc. www.tstar.com
