I have a 1995 16 ft C-Dory Angler. The boat has developed about 3 or 4 one foot long hairline cracks in between the 2 seats in the bridge area. They appeared fairly recently and I have heard a little"crack" sound at times when I step in this area between the seats...It has me somewhat concerned. Has anyone else experienced this problem...do I need to grind the area up and put down some fiberglass or is it more of just a surface problem? Thanks for any suggestions!
