[Alberg30] barrier bottom protection

[Kevin Blanc]

If I had the whole thing to do over again, I would do what Mike says. 
Pull the boat every year, have it blocked well, and let it dry.

My Alberg (#254) was blister-free when I purchased it 11 years ago. For 
several years, I left it in the water for two seasons, hauling it only 
long enough to scrape/sand/paint with a soft ablative paint.

I developed blisters. Not deep ones, and not too many, but blisters none 
the less. I hauled, sanded to bare gelcoat, dried for six months,  
ground them out with a dremel tool (there were areas of dry laminate 
just beneath the gelcoat), filled, and barrier coated. No signs of 
problems since then. In my estimation, if the hull is allowed to dry, 
the barrier coat products really do work.
