If you can get to a 3D solid modeling CAD system, you could model strip shapes, including bevels. Tolerance buildups on assembly are always a problem, so every 3rd, 4th, or if your lucky 5th strip would, as you noted, need to be adjusted to get you back on the scheduled location for the next strip.

Until several people try and fail, I would say it's feasible, but expect unforseen difficulties to arise. If you can get these issues resolved, it would eventually evolve into a doable process. But at that point, why not just layup cloth in a mold?

The hand making of the boats is, to me, part of their appeal.
