Blisters on Gelcoat

[jkallen21]

2006 SANTE - left it in the water all summer. Now I have some blisters on various parts of the boat. I understand it's cosmetic only. I'm wondering how much this type of thing is to have repaired - and if I do, will they start coming back on other parts of the boat later?

Thanks

I don't get how leaving a boat in the water causes blisters. My first boat was a Sea Ray, which was left in the water (seasonal) for 40 years...no blisters. My 92 American Skier had a lot of small blisters along the water line. My 92 Nautique has some, also anong the water line. My understandind is that small, intact blisters are not an issue, large ones that crack may be an issue. My thinking is don't fix it if it aint broke.
