We don't offer plank loftings (patterns) for all of our boats, but we received so many requests, that we reluctantly added these to our catalogue. Why reluctantly? because in order for them to work for you, your boat must be set up precisely as spectfied. If your setup is off, the first plank pattern will work, but as you progress toward the sheer, the fit will become less and less what's needed. The more planks, and the more shapely they are, the greater the ramifications of an inaccurate setup. And while that may sound a bit disheartening, we want you to understand right up front that this is not "boatbuilding for the complete idiot." Patterns do not relieve the builder of the responsibility of doinf accurate setup work.
