How many builds does it take for a basket mold to be a cost effective building method? It must cost almost as much as 1 hull by itself?
Depends on the value of your time We will probably offer a mold set for free when a club/organization buys 10 boat kits, or a discount on the kits equal to the mold. To buy the molds separately would cost a little more than the plywood for one boat. Jacques spent MANY hours on that mold. A basket mold for one of our other designs does not need to be nearly as elaborate as the optimist molds.
