Many thanks for your reply
So the boat building company would be my client and I would be the stylist that would design the boat. Then they would build it. I get paid for that a set fee. If I am only going to be paid a few thousand then I see there's no point. I would rather pay to setup my own boat building company and reek in far bigger profits. I had hoped that I could perhaps make something like 10-35 percent profit from any boats sold that I design.
