RE: Manatee Blister Questions
Gary: *Those blisters are pretty much part of the game of owning a Manatee, or lots of other boats of that era. *The Manatee, of course, is a fully cored hull, and needs to be watched for water intrusion, but it's not like balsa or something that rots. *Using a moisture meter and hammer, you'll know whether there's any real delamination problem or not, but I pulled Bucky just a couple of weeks ago and re-checked it since the survey was done about 6 months before. *Same results. *The hull had a about a half dozen blisters just like the ones you described. *I ground and filled, then bottom painted it again with Trinidad. *It really didn't need to be done now, but the boat was in Daytona Beach, and I didn't want to yank it again here in Miami 9 months from now. *Barrier coats work well, but there's probably nothing wrong with your hull. *Don't spend 12 to 20 grand on a peal and glass job unless you've got trouble, and it doesn't sound like you do.
