Hello all, thanks for the replies

To clarify a bit.

Approx 10 years ago the hull was stripped of all anti-fouling paint and then 8 coats of epoxy resin were applied, no filler added. This was done by my father and he can not recall the details has to how he went about doing this other than what is mentioned above.
Each spring if I find any blisters that appear to have penetrated the epoxy barrier coat, they are dremmeled and dried out. I sand the anti fouling paint away, approx 4 inches radius around the blister and apply epoxy to it, no filler. Usually 2 - 3 coats, sanding and feathering in between.

The vast majority of the blisters are water trapped between the anti-fouling and the epoxy barrier, which leads me to believe, as suggested, that I am not prepping the hull correctly before the anti-fouling paint is applied.

So, next spring, should I sand down the anti-fouling to bare hull and start with a fresh layer of anti-fouling?
My main concern is to get things done right, an ounce of prevention being worth more than a pound of cure.

I am currently using Interflux bottomkote XXX as my anti-fouling paint.
