Triaxial roving has had the same makup ever since I first heard about it. The 0 degree has the same weight as the combined weight of the +- 45s.
I have a 25′ daycharter cat being built in Seattle. The sample testing done by Gougeons gave very low results. And the burn test reveled that it only had 20% 0 degree fiber. No wonder the low numbers.
Orca has two different 20 oz. triaxial spec sheets apparently. Be very careful which product you get.
The one that I am used to has 354 gsm for the 0 degree and 200 gsm for each of the +-45s.
The other one has a 0 degree of only 142 gsm and +-45s of 292 gsm. each. That is clearly an inferior product but it is still called 20 oz. triaxial. Beware. First the bad one, then below, the good 20 oz. triaxial. I wonder who thought skimping on the 0 degrees would be smart?

Meanwhile the Miami Bed Boat Continues
I have been tempted to walk away from this job more than once. I decided I could warp the hulls enough to carry 700 kg of motors. 1543 lbs of outboards. It is for daycharter out of Miami but they didn’t know the USCG would require railings. I’m at version 21 now.



37′ Cat Update
A slightly stretched version of the 37′ cat has been updated. It is being owner built at Betts’s Boatyard in Anacortes, WA. Foam/glass.



They Are Back. Lake Chelan Ferry
A Sailing Cat Becomes a powercat
This 44′ catamaran to be built in Tampa was originally envisioned as a sailing cat. It would use the Sunny Days 42 hulls extended. Using CM construction.
Owner decided to make it a power cat instead.


Miami Bed Boat
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.
