I am in the process of buying a sailboat and just had it surveyed. The surveyor found and pointed out some blistering on the hull. Probably about 25% of the hull in varying sizes but predominantly under dime size. The surveyor explained blisters and how it doesn’t necessarily mean the deficiency in the structural integrity of the hull. He also said it is not uncommon for a 38 year old vessel to have blisters. The rest of the boat is in great condition. Comments and thoughts appreciated.
