This is how you sleep in a wide berth with a tiny trimaran. Muffalo a 24′ tri tearing up the water in northern Italy.

Stephen mostly works with the big boys in volume production marine, wind blades, and aerospace. As a result, room temperature cure epoxy is barely on his radar. That is very different from my DIY guys and the custom builds who both use the above epoxy. He speaks highly of Derakane 411 which is a vinylester that he calls more epoxy than vinylester. The big boys have less concern about impact resistance than cruisers and charter guys do. My one concern with the high temperature epoxy is the brittleness. I will keep studying with Stephen’s information in mind.
Stephen Crane also mentioned some glass fabrics that could change everything. A couple of fiberglass products from the CPIC mill in China have properties close to S glass but at cost and probable volume of E glass. He has some samples of the Tm and Ht products and will be testing them for hard numbers.
Friday I was lucky enough to have lunch with composites guru Stephen Crane. There are huge things shaking out in worldwide composites and he keeps up with that better than anyone I know of. He is now working with Space-X. I’m kind of in the weeds in my corner of the world, with my head down trying to keep up with peoples deadlines most of all. The information was much appreciated. The following assumes I heard all correctly.
The bullet points would be:
Core
New fabrics
New resin
Cg of composites innovation.
Today I will limit to core as I left my notes back in the truck.
Gurit is having some issues with supply and pricing Corecel foam. Mitsubishi owns the patent now. Contact Mitsubishi for a more reliable source.
Divinycel’s days are numbered as a core. It’s manufacture is already banned in Europe. The reason is that dioxin is created during its manufacture. It is now only being made in the US, and despite republican claims that dioxins are one of the major food groups, those days are numbered. It is being replaced with PET (Polyethylene-Terephthalate). The properties are not as good yet as crosslinked PVC of the same density.
and at the printers. Usually a week to get them back. Still too big to email (0.3G) but will sort some kind of FTP soon.
I will have electronic study plans (PDF) on the site soon also.
Meanwhile plans to finish stacked up. Fast as I can.
Too many deadlines. The new Design book is still not done. I’m going to duck out for a couple of days and get it done. If I don’t, I will be spending all my time answering calls and emails about where everybody’s book order is.
Even sailors who did every official thing right are having their boats seized by the Mexican IRS. Richard at Latitude 38 has reported this best and most completely. And Profilgate was also seized.

A little bit of a cheezy wide angle view of one of the Sunchaser 58s that is not an Oregon bootleg.
