My previous boat had about 400 blisters.

I ground each one down with a dremel tool .

I then waited a few weeks , as it was summer and filled all the holes with epoxy putty and faired the hull. I then put on 3 coats of Interprotect - Interlux InterProtect Epoxy Primer‎ . Then one coat of blue bottom paint and 2 coats of black. End of problem. When I saw blue paint I knew it was time to repaint. It was a simple job but tedious and time consuming.  I do not see the logic in removing all the gel coat from a boat if there is not a problem.

Subject: [Amel Yacht Owners] Maramu blisters

 

 

I have some small blisters since I purchased me 1985 Maramu 7 years ago.  I've always been told that they were small and just cosmetic.

This latest haul out in NZ I'm being told that I should have a complete osmosis repair and it could take 2 1/2-3 months for the hull dr dry out after grinding and before 3 coats of epoxy can be applied.  The cost is estimated to be $25,000 nzd.  

 

My question to other Maramu owners is, is this a common problem with older Maramu's?  Has anyone with a similar problem taken a different approach (like grinding the blisters individually yourself vs using a me jibe to skim off the entire chop layer of fiberglass.

 

Thanks for any input you can furnish.
