Removing a bit of hull core foam

In order to strengthen the area around the slot in the hull where the centerboard case will be joined, the core foam must be removed and replaced with a high density filler. The forward exterior portion of the centerboard slot can be seen here in yellow. This is the natural color of the Kevlar sheathing that runs the 3/4 length of the boat. You can also see the inner skin which is 24 0z. triaxial glass. 
To remove a portion of the hull core foam, I found that a 3M paint stripping wheel works fairly well.  It is aggressive enough to make short work of the foam yet tame enough to prevent the fiberglass skins from being damaged in the process.
