Angling Addict is spot on . Bottom paint is there to prevent aquatic growth on the hull. A barrier coat of epoxy is what you need. 

   I had exactly the same problem on a Seaswirl WAC that I kept in a slip. I went to a fiberglas guy in the marina that came highly recommended. He sanded the blisters and used an epoxy barrier coat, which is like forever. Then if you desire , you can bottom paint to retard growth. Not cheap, but a permanent solution.

I have one that was used only a few times, let me know if you are interested in replacing your lost one.

Very Nice king, did you get a weight on that fish ? I have fished  off bluffers park , Port Credit, and Bronte, there are big fish out there. 

I have some that I would be willing to part with . What size are you looking for ?
