Osmatic blisters
I am tired, worn-out and reluctant to reply as there are many rumors, myths,and scares out there, and methinks it should be cleared up, by me, ha, certainly not, but I am willing to contribute to the debate.Was your surveyor SAMS or NAMS, just curious?Curious that he would say that they were NOT osmosis? Unless they were in in the PAINT then indeed they are osmosis, but this is usually NOT serious, can it be? That is a great debate now. A promenent surveyor said, "a vessel has never sunk yet due to blisters".Methinks that part is true. Are they serious? Depends on who you talk to, but since the emergence of blisters on fiberglass boats; boat yards have made hundreds of millions of dollars, 'peeling' preping, faring, not to mention the months out of the water to "dry out the lamiate" which is true if you are going to fare and re-gel.Not a hoax, but is it necessary? And the boat goes on.My view is, how deep are they, and if they are through the gel-coat, then they will need to be dealt with.Even a hair-dryer (instead of spending a month out paying lay-days) to dry, and micro-baloon to fill works, and it is important to dry out as best you can, but you will never get it dust-dry, factory dry.Whitsundays, the only ones I know are in Auz, Magnetic, Green, and Hayman Islands; most beautiful reef on earth, lotta deadly critters though. Moolulabah is a great yard...;-)
