If they are visible on the hard, they are visible in the water.

Re: Blisters Visible to Diver?

If you clean the bottom with a rag or a thin scotchbrite pad, you will feel the blisters before you see them. I'd ask a diver to clean the hull and check for bumps.

Re: Blisters Visible to Diver?

There are too many boats on the market now which can be bought cheaply to deal with a boat which had 50 quarter size blisters which were not fixed properly. Until this boat is sandblasted with baking power and then dried and peeled and then built back up, you are always going to have problems with blisters. It is not a hassle I would want to deal with. Either fix it right the first time or nickel and dime yourself to death for the life of ownership of boat and have something which would not have much resale value. If the diver can see blisters now underwater, then you have some very serious problems.

Yes, a diver will be able to tell if there are any blisters on your hull, but if the bottom has even a light coating of slime, it will need to be cleaned first. Fortunately, the diver will get a very close look at the surface of the hull while cleaning it and will be able to tell you if there is any blistering or not.

If he knows what he's doing, he'll be aware. Not all hull cleaners know very much about what they do, however. Be sure to find someone with lots of experience and a good reputation.

If the diver can see blisters now underwater, the OP has no more of a serious problem than if they were seen in the yard. Maybe he has a serious problem, maybe he doesn't. Blisters are not inherently worse simply because they can be seen underwater. As previously noted, nobody's boat has been lost due to blistering. Nobody likes blisters, but they don't mean the death of the boat and in most cases, don't require immediate emergency remediation. Many boat owners never do anything about their blisters at all and never suffer any consequences.

Re: Blisters Visible to Diver?

Filling blisters has been very common, expecially before the peeler came into it's own. BTW, the boat I mentioned above (so wet that it had blisters on the inside!) had no blisters at survey (outside). When it was stripped later, there were years of filling-in-blisters evident... different colour fillers!
