Holy Blisters Batman

Dave R · 09-09-2007, 08:07 AM

There were a couple of articles recently in Passage Maker magazine (August 2006 and September 2006, back issues area available) dealing with how blisters form, how to prevent them and how to fix them. They are easily the most comprehensive articles on the subject that I have ever seen. I'd read them prior to doing anything.

Blisters are almost always just cosmetic, not structural. On a seven year old boat, I would consider a less drastic approach, before tearing up an otherwise sound hull. Let the boat sit over the winter, the blisters may dry up on their own. A lot of boats have blisters in the fall that are gone in spring.

If they're gone, then think about have a barrier coating applied, call Four Winns and see what they used or recommend, it worked for seven years. This may reduce the future blistering, or if you're lucky prevent it. Even if they're still there in the spring think about living with them unless they are really horrible.

If you let the blisters dry up, they will almost always come back when dropped back in the water, unfortunately.
