Practical sailor did a test last year I believe on bottom paints. Florida was one of the areas they tested. Will have to see if I can find it.
As fastbottom recommends - ask the locals. They will tell you more or less what works/does not works.
Also, I don't believe there is a magic solution to fouling. You need to clean the bottom at some point during the season - either pay a diver or do it yourself...
