When I pulled my 1993 Hunter 23.5 out of the water for the winter and put her on the trailer I looked underneath and found 2 spider cracks about 2 inches long on the front edge around the swing keel box. I can't get access from the inside of the boat to see if they are all the way through the gelcoat. Anobody that can give me suggestions on how to repair or what to use would also be appreciated. This will show me if it's a job I can do or if I want to find someone else to do it for me. I didn't find any water inside the boat so I'm curious if anybody has noticed this before or if it is a sign of major problems to come. Thanks for your help.
