A reliable source on another forum I frequent made a comment that boats of the day (sailing, beach catamarans, 1990s and later I guess) were made the same way as surfboards. I took this to mean that the master was basically hand carved and then molds were made from the master. Does that sound right?
It strikes me as amazing that molds for a boat that required two, perfectly symmetrical, mirror image hulls, that are going to be manufactured in pretty high numbers (thousands) would be made from hand carved masters.
Am I totally misinterpreting his comments or does that sound about right? How else might you go about doing it? I'm talking about hulls ranging in size from 16 to 21 feet.
