Arrow, You are right, but financing this could be an issue. I think at this point I will thin up the hull sides with a 6" grinder, with a pad made for removing a lot of material quickly.
Don't forget that the bottom is 3 1/4" thick. So a lot of weight where it's needed most. I also have an old bronze centerboard that weights about 40 pounds which may be incorporated to give me a lower center of gravity.
