I read in an archived post that plywood weighs 50% more than solid wood. What if you built a S&G out of thin wood, such as Redwood, rather than plywood? My thinking is that if you used a layup such as Mr. Roberts suggests, with Kevlar on the inside of the hull, you could save some weight without sacrificing strength.I am thinking more along the lines of composite construction, rather than classic construction. Almost veneer thickness. Am I missing something? Secondly, how many boats must a person build before they are satisfied? I already see that I'll have to build another, knowing that I can improve on fit, finish etc. Thanks to all the folks who share their hard earned knowledge here. It is much appreciated! Mark
