I just got some time today to crawl under the hull of my 170. The hull looks great. Just the 3" long crack at the center of the back. There are some scratches/ digs on both sides were it scraped against a dock or something. The swing keel has the 2 fibered tapes on either side the starboard side needs some new double sided sticky tape on the rear 4" or so. Need to look up how to remove the tape used by the shrink wrap guy. There are 4 pieces of tape stuck to the hull that need to come off. I am thinking some careful heat application with my heat gun. I am very experienced with keeping just enough heat in the right place to get the tape glue warm enough but not the base.
