I decided on leaving my ski boat in the water at the dock this summer instead of taking it out of the water every use. This last time it's been in the water for a little over a month and when I took it the fiberglass that was below the water line has bumps all over it like bubbles in the fiberglass but the clear coat and paint still look good not peeling or anything. Does anyone have an idea on what could have caused it or how I can go about fixing it now that its done?

It is a bad problem. The fix is usually expensive. See this article before you let anyone do a jackleg job.

What size are the bubbles in diameter and how close are they apart? Are they all over the area below the water line or are they concentrated near the water line?

It's moisture under the gelcoat. How old is the boat? Repair is expensive but if they are lots of small bumps all over then you can just keep using it. I bet many boats on lake Martin have the same condition. They just don't make them like they used to. Or do they, my 1982 Hurricane had the bumps and it was stored most of the time out of the water.

You might want to make sure Talon has a picture of your bottom to see some of the work you do. I mean the Seacamper bottom.

It looks like a golf ball pattern but raised. More near the water line than on the bottom. Its hard to get a good picture its happening on the white fiberglass on the bottom but not on the other colors of the bottom that where in the water too.

I am not an expert on the subject but I did fix 110 blisters on a houseboat this summer. If the blistes are larger than 1/2" in diameter I would recommend having them repaired. The fiberglass behind the gelcoat will deteriate causing a weak area in the surface of the hull. The houseboat had blisters from 3/8" to 2" in diameter and the fiberglass was saturated with liquid and deteriated as much as 1/8" deep.

I wish you could get a photo of some of them. They sound like blisters. I can't think of what other they would be. White is often hard to spray and sometimes it's thin or heavy depending on the sprayers eye in application. If too thin this is where the water got in. This could be why other areas have resisted. If it's blisters, there's no good news. Depending on the value of the boat and the severity of the damage it almost always ends up that the repair is more than the value of the boat.
200 blisters on a 30' Sail boat is more economical that 200 on a 17' bayliner. Ya know.

Try to get us a photo and maybe someone can tell you what you could do.

One thing, if they get to bad the boat can disintegrate from delamination at speed. So be careful.
