Having built two Chesapeaks and two Shearwater hybrids, I'm now looking to try one of Nicks beautiful designs. (This really is addictive isn't it!!) I really like the Night Heron (18'), but this boat will be for a smaller paddler, so I'm interested in the Petrel at 17'. I will be building an all-strip boat. I'm used to the step-by-step CLC type build manuals and I'm concerned that I might dive in over my head with the Petral. Will Shade's book be enough guidance? Any feedback regarding build difficulty, performance or whatever would be appreciated.
