Viewing this with interest as to what the kayak will look like once completed!
An observation on my part I'm having a hard time seeing how the bottom of the hull will be smooth (like the original hull). How are you intending to "blend" the glass to the bottom of the hull? I understand that you will be glassing the inside, but what about the bottom outside, won't it leave a ridge around the "box"? I see this as being one of the larges hurdles of the project.
