You can find the challenge at George Roberts' site. (see link)

My original post in this thread was about a process I felt would save weight and increase strength when building a strip kayak. I feel that 1/8 inch cedar strips would save a lot of weight, and not weaken the boat.

I am interested in the boat you built with 3/16 strips. As there is really no way of telling short of destructive testing, in your opinion, was the boat as strong as a similar boat made with 1/4 strips. Was the hull or deck more flexible, did it flex noticeably if you lifted it while loaded?

Also what kind of layup did you do on this boat? (single/double-6oz./4oz)

Thanks for any info. Ian Johnston
