One thing to remember, they do not have the R&D time invested in building molds...... Who knows who much they spent. How much Glass material is actually needed for a hull build? How Much epoxy. With buying the molds, all they have to do is determine what the layup cost will be from their sub. What materials they have to buy (hardware, glass, epoxy, etc etc), and then determine what profit they need to put on the hulls and how many do they have to build to recoup their cost of the molds. After the molds are covered, that is just extra in their pocket.
