I have a 18ft jet boat and i had Ultra Boats do mine for $2400. Built the frames, glassed them, new foam, and vinyl, also had a hatch built to help save my drunk friends fingers from the alt belt.
plenty of leg room in the back.
I had the set up like in the second pic. were the back seats face each other, this way there is more room.

SUPER NICE INTERIOR CRUSADER! WE CAN'T GET THAT LEVEL OF CRAFTSMANSHIP IN THIS AREA.
