400 half inch Osmotic Blisters
I am new to sailing and have recently made an offer on a 1985 Catalina 36.
The marine survey notes 400-500 half inch Osmotic Blisters and 10-12 2-inch blisters.
I have been advised that I only need to repair the 2-inch blisters. However I am concerned with that advice... should I be concerned with the 400-500 Osmotic Blisters?
If so what are my options?
