(06-22-2006) Still haven't broken out the grinder...but I did use the cordless circular saw to assist in getting more floor out. Looks like the stringers are not going to have to be replaced. YEA! Under floor is devided into 3 sections...front, rear, and transom. There was the "flotation studs" in the front and rear section. There was no way for the water under the floor in the front to make it back to the rear...and from the rear to the transom. I am going to have to design some drainage system into my rebuild.
