To start, I have no experience with Fiberglass repair but do have the DIY skillset to attempt them. I picked up a 13FT Riverhawk for use in the rivers in North GA and it has some damage to the keel near the bow and stern and also a spot on the corner of the stern. My question is...based on my pics...how bad is this damage and how hard will it be to repair? Also, since I plan to run this boat over shoals and will certainly scrub some rocks from time to time, line-x should help shouldn't it? EDIT: Images fixed.
