About to do blister repair on my Hunter 30 (1980)...

Just so I know what's behind the blister, anyone know what the thickness of the hull is?

I've been using an electric die grinder with a 2" disc on my 1979 H30. Hull thickness varies on mine. Maybe a 1/4" on the sides and increased to about 1/2" on the bottom. I just ground out the bad stuff but made sure I didn't go through.
