I need a few opinions on this. So I just got a free 1973 Stuery 16' boat and motor from a friend. It has some chips in the gelcoat and the gelcoat is worn off of some of the hulls center line below the water line. No apparent damage to fiberglass I see no dents or crushed areas but fibers are visible . The question is what if I don't fix these right away? The boat was free and I don't want to sink a lot into it especially before I test it mechanically for a season. It will be on trailer when not in use not just parked in the water. What will happen if anything if I leave it this way?
