I also have a set of molds for the 84" Apache,I got these from a friend of mine that I think got them from joe with the big turbine hydro, I have seen some pictures of a boat that was said to have been made out of these molds running nice with a inline at the shootout CRC puts on from a few years ago.I have not built a boat from them yet but they look like they will make a great foundation to work with. The finish on these is ok but will not produce a nice finished gel coat boat it will need to be painted, I do feel with our standard lay up using mat and carbon fiber it would be a strong hull, but for the twins I would do 2 layers of mat and the carbon fiber, The second layer of mat would only be on the bottom of the hull to keep it from twisting.Just up loaded that picture, That is our 72" sea hawk sitting next to it, Man it looks small.
