As you can see in this picture, there is like a 6 inch gap between the edge of the floor and where it meets the inside hull. Mostly its twards the back of the boat. I have to find a way to fill these gaps so that water does not lay in there and drain below and rot things. I cant believe how much grinding is involved with this project. I have been through about 9 grinding wheels so far and im supprised that my angle grinder hasn't quit on me yet.
