Some progress

Spent a few hours today grinding out some 40 more of the blisters. Sizes ranged from the size of a dime and 1mm deep to a couple inches across. Most are in the top couple layers of glass and the size of a quarter when cleaned up, but a couple were deep. None go through to the core that I have found and all can be ground dry. :) The hull construction is interesting. There appears to be no gelcoat, just a thick layer of baltiplate under some regular antifoul. There are at least three layers of ~6oz cloth over a light mat before you get near the core...and there might be another layer of cloth against the core, but I have not been in that deep to see. There is heavy cloth inside the hull, and I see no need to play with that. I'll get some more pictures posted soon. Other projects this winter will be repair of the seats under the traveler (recore) and strengthening the forward bulkhead tabbing.
