How thick does a hull need be? Or is more glass always better?

I am refinishing a Nantucket Clipper built in 1971. The gelcoat has been removed, ground off, and I am deciding how best to redo the hull. There are some blisters in the bulge of the hull below the water line, less than 20, 1" blisters per side, reason for stripping. It has been in a barn for 10 years and is now very well dried out. I have been told that using an epoxy barrier coat below the water line would be good to protect against more blisters. I have also been told the late original owner had plans to lay up biaxial cloth/mat with Vinylester resin to finish the hull.
What would be the benifits of more glass when the hull is already 1" to nearly 1/2" thick where the blisters are. I am tempted to lay up glass along the rough sections of the hull, fair it off and add barier coats of a 100% epoxy product I have used before called Durapoxy.
