This is strange and I don't know what to make of it. All winter I thought about the itty-bitty blisters I have on the port side of my boat right below the boot-stripe (still above the water line) and whether they go below the anti-fouling paint under the water line. I looked at them carefully today and they are just in the white stripe (is it a stripe"). There are now a couple of them that have "popped" or flaked out and what I see underneath appears to be the same color dark blue as my boot stripe. Is that possible? They really look like the paint right there is blistering and when the little hole/blisters come out there is blue underneath. Or is that fiberglass underneath there? It appears to be a shiney blue and really is the same as the boot stripe. Have any of you ever seen this before?

Dave,
I believe all of the hull striping is masked off inside the hull mold first. Next, the hull color is applied and then the masking is removed. Then the boot stripe color is applied as a <i>swath</i> of color inside (or behind) the hull color. Hence, there are two overlapping colors in the vicinity of the hull striping.
When I opened all of my blisters the good fiberglass was a translucent greenish-gray color.

Ya got all that ?

OJ, I don't see anything greenish-gray, just blue. I am wondering if these are blisters I need to worry about? I intended to "pop" the blisters this fall when it can be out of the water all winter. Will I still need to do this? I suppose it makes sense to do that in order to cover the blue, but it appears as though the boot stripe may have "stopped" the blisters from getting into the hull. (Does that make sense?)

If they're breaking open and getting saturated with water, you'll want to give them attention at some point.

Just not urgent <i>or</i> important, yet .

Ill bet dimes to dollars that the stripe with the blisters was painted on. The blisters your seeing are just between the gell coat and overlayed paint. If you had a real blistering problem they would be bigger and contain a liquid in the blister.

I have the same pinhead-sized blisters in the stripe--many had popped and left tiny white spots in the blue stripe. When I bought the boat, my surveyer said they were common, harmless, and probably caused by algae. With that opinion, and given that from 10' away they are not visible, I had forgotten about them (until just now).

Sorry to remind you about them, Dave. I am now cleaning that area with toilet bowl cleaner (something I gleaned from this Forum - works great for the most part!), and I am uncovering a few more. They exist only in that stripe area. I think I'll wait until I pull the boat this fall and then get rid of as many as I can and then refill them. I did pop one of them and there was no fluid in there. There was almost an audible "pop" or a "crinkle" (does a "crinkle" make a sound?) when I stuck a fingernail into it.
