Check Your 20 oz. Triaxial

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?


This partially built 42′ catamaran is for sale in California. The builder died. It also has a lot of tools.

“My brother, Tim Beyer, purchased your plans for a 42 foot Cruising Catamaran approximately 5 years ago.  He has built the hulls, bridge deck floor and dagger board cases from plywood composite and fiberglass.  It needs an interior fit out and rigging.

I would like to sell the partially completed project with the plans, all power tools, supplies and materials, and a 38 foot trailer that can haul the hulls.

My brother put his heart and soul into this catamaran and unfortunately died before he could complete it. Consequently I’m looking for a buyer who appreciates all the love and skill he invested in this boat!

His boat is currently located in King City which is an hour’s drive from Monterey.”

As you can see, it is almost built. CM developed plywood.

$60,000. reduced to $30,000
