I have decided not to do it. Its too big of a legal issue and probably will result in a small gain for such a large amount of potential problems.
Actually my biggest fear is of selling it. Not being able to, or having the buyer come back and sue me after he gets sued. Yes, California living.
Its just too big a mess and headache to deal with. The more I think about it, the stupider the idea gets.
It is after all only a RIB, not a high powered racing boat, (where on is trying to extract every mph.)
I'll save my pennies for a dual motor super RIB or just get an offshore style speed boat made for the ocean...
