One other comment. Tollycraft was pretty strict about the stability of his boats. He required that they be 'Columbia Bar' capable. I know this because I met one of the guys who used to test boat designs for them, if they didn't perform well, they didn't get built. So if the boat isn't 'stable' then look to what has been changed. Weight up on the fly bridge, an added 'radar arch', added hard tops, etc. Also, many of us often run all chain anchor rodes adding hundreds of pounds to the bow. Sail boats often use chain/rope (e.g. ~30' of chain then all rope) to keep bow weight in control.
