Filler
It is difficult to advise you about the damage to your boat with out being able to actually look at it. However, I will relate the repairs I made to my boat while having the board out to fix the pin. There were several "gouges", nicks, and areas of abrasion on the hull in and around the center board well. These were all in the area where the brackets which hold the pin are located. None of these were through the hull, and I don't believe any of them were serious enough to cause leaking. I repaired all of them - again using the West System expoxy and the appropriate filler for their product. Some of these problems were actually under the brackets, and were only discovered when I removed them. If your problems are more serious than what I have described I think it would be advisable to have a "professional" take a look. A small amount of money spent up front for good advice might save you many dollars in the long run. I will check back with the forum in case you have any more questions for me. I find it frustrating when I recieve help from the respondents, and then have another question. I rarely get answers to follow up questions.garyg
