I have a 2003 Hunter 356 that has gelcoat cracks. Most of these are shallow (maybe a dozen) and just need repair. The BIG concern is around the inner chainplate on both sides. I had a survey last month and he suggested I beef up the coach top between the windows in the chainplate area to prevent this from recurring. 1) So; does this sound reasonable or needed? I have not read of others having this as a structural problem. Leads me to consider a smaller strengthening effort as adequate? Does a couple layers of fiberglass inside sound like a reasonable correction or should I opt for the bigger SS support on the inside that he recommended?
