Not really.
I realize that it is applied to prevent growth. But does it actaully act to prevent water from entering the gelcoat and resin/fiber?

I don't believe my boat model is know to have blister problems, and my 30 year old hull (in water 7 months / year) does not have any, but after reading the above link on blisters, I guess it is possible to have water damage / weakening of the hull, without blisters.

Without the any apparant damage / blisters, it is hard to justify the work / cost of stripping down and applying a true barrier coat.

If you don't have blisters on a 30 year old boat I wouldn't worry about it. Different manufacturers had different severity of problems. It seems to me late blistering started in the mid 70's and got really bad in the early to mid 80's. I have seen Islanders with 6 inch blisters, C&C with blisters to the core and Newports with none, all the same age.
