We have had this boat in our shop many times, this time the boat slipped off the trailer and landed on the boat ramp! So up onto work stands to access the hull bottom. Most of the impact was taken by the back of the keel but there was further damage through to the bow where the hull made contact with the concrete. The aft keel skin was built up again with glass and epoxy and refinished, as was the rest of the hull. We gave the entire hull bottom an acid wash and polish while it was up.
