Hello All, I have a 1977 Seaswirl that sits in the lake 8 months a year. I pull it out in the late fall and wash all the scum off of it. In the spring I pull it out of storage and rewash and wax it. When I pulled it out this year I noticed blisters all over below the water line. When I started to scrub it I found little pits that are thru the Gelcoat. I stopped washing it. What can I do to either repair these and/or make it usable again? The fiberglass is still in good shape around the little pits. Is it time to get a new boat? Help...

I wouldn't put much money into a '77 boat. Clean it up, give it a good coat of bottom paint, and call it done.

Hi Augwen,

Perhaps the manufacturer would give you some guidance too. Good luck, let us know if Seaswirl is receptive to helping out with one of their older boats.

Successful Boating,

Augween, It is strange that the blistering didn't happen before. The cure is to fill the blisters with marine putty, sand smooth and apply several coats of a 2 part epoxy primer to seal the fiberglass. You may then apply a polyurethane topcoat suitable for underwater usage or antifouling paint.
