I see on Steamradio that Russell Brown has just discovered tortured plywood chapter in Gougeon’s boatbuilding book. http://www.ptwatercraft.com/Begining%20Tortured%20Plywood%201-6.pdf And Steamradio is typically in awe of anything multihull royalty do. I do see that if he had used the tortured plywood chapter of the CM construction manual, he could have saved a lot of work and mystery. I do understand that for many people the goal is not to have the boat but to embark on a personal discovery. I get that. If the goal is to get into a developed ply (or other) multi, my builders and I have probably sorted out the mysteries long ago. The KHSD CM Construction Manual has a chapter on tortured ply and of course the CM for bigger boats. (Ever try to bend a 9mm sheet of ply?)
I will gather and post here some of the illustrative tortured ply pics in the Manual as soon as I get caught up on deadlines.
