I was looking at a boat today, and there was cracking of the gel coat around the swim platform mounts and also it looked like something was making nice round circles underneath the gel coat fiberglass. The gel coat was also cracked and peeling away from around the exhaust ports. Also, the fiberglass was cracking around where the exhaust goes through the floor by the stringers. Anybody have any idea if these are some major concerns? or more cosmetic?
