It is nice to have a choice. And carbon fiber is indeed not for everyone.

Default Carbon

FYI, We will still use Carbon on critical areas on the boats, all Models.

That boat will be real nice minus the canopy. I had looked at the first one @ Martin and did not really care for the canopy. I am sure the new open version will be a nice improvement for those individuals wanting an open cockpit configuration.

Unfortunately, a basic concept seems to be lost these days when it comes to composites.

A Composite, by definition, is quite simply a union of two or more materials, typically a fiber or powder and a matrix. Fiberglass/Vinylester is a composite. Carbon Fiber/Epoxy is a composite. Kevlar/phenolic is a composite. Ceramic particles embedded in soft metal (brake pads) is a composite. Hell, even plywood is a composite.

What are they actually referring to with this "optional full-composite lamination schedule???"

"A full-composite boat does not ride as well in the mid-range as a vinylester one."
Really? My fiberglass/vinylester composite boat seems to ride just fine.

Please elaborate.

Haha, I was going to post the same before, but since I knew what they were getting at I decided to let it be.

Technically correct, of course, but what builders generally mean when they say "full composite" is epoxy instead of resin and carbon fiber, E-glass, Kevlar and other variants in place of "traditional" fiberglass. But you make a good point, nonetheless.

A perspective on carbon fiber construction from a seat of the pants example: Three years ago, I went from an aluminum mountain bike to a carbon fiber mountain bike. I saved almost four pounds. But the stiff ride of the carbon bike is such that you need to be on your game or it will toss you. It goes exactly where you point it and does not forgive errors.

Good point.

FRP boat layups with polyester resin and "E" fiberglass mat is the standard that most boat builder have used for years. Vinylester resin in being used by many companies these days.

The standard layup with use vinylester resin with a proprietary combination of "e" and "s" mat with kevlar/cabon fiber reinforcement.

The Carbon composite layup will use epoxy and a proprietary combination of "e" and "s" mat with kevlar/cabon fiber reinforcement. This will then be post cured. Much stiffer than standard layup and approx. 300-400 pounds lighter
