Hey any carbon fiber experts out there, I have a question:

How much weight, expressed as a percentage, will building a boat out of carbon cloth save vs. the same layup schedule in "regular" fiberglas mat?

Example; if you built say 2 Inter 20 hulls, in the same mold, one hull useing carbon cloth, the other uses fiberglass, how much ligter would the carbon hull be, same amount of resin, same amount of foam sandwich, and same gelcoat on each?

Or...is part of the carbon weight savings in that you don't need as many layers of cloth, because it's stiffer?

Manshed, do you know how much weight you are saving using carbon instead of glass?
