I was reading a boat reviewer and I can't remember about what boat but the
reviewer mentioned a newer system rather than gelcoat for the hull finish
and mentioned how much better than gelcoat it was. He said it was being used
on a few sportfishers and the sailboat building industry had yet to catch
on. Can't remember the name of the material mentioned. Any one heard of this
newer material and the name?

Are you talking about vinylester? It's still not as good a barrier to water
permeability as epoxy. Gelcoat is just a mix of polyester resin & wax. It's main
benefit to the boat is that it takes a gloss & it's cheap (although this
benefits the boatbuilder more than the owner)

That was it. He seemed to think it was superior.

Is this really true? I think the partition coefficient is probably
comparable. The key to osmosis resistance is not the water barrier but
the lack of voids that can be filled with solutes...
