I own a Freedom 21 which I will use for Wed night racing. Last year I used ablative bottom paint, and boat is in the water from about April to November. Should I even consider a hard racing paint, and if I use it, how fast will it slime up in the Chesapeake Bay (or better put, how often should I figure on scrubbing?).

To keep the slime off your hull in the Northern Chesapeake .... Next time add oxytetracycline crystals to your bottom paint. Either get it from your veterinarian or buy it (called "compound-X"). If you can, make it even finer (powder) by pulverizing the crystals with a mortal and pestil. Will only last one season.
Also ... get your ablative bottom paint as absolutely as smoothe as possible by either applying with a roller, then fill-in all the ''roughness'' with a plastic trowel OR by spray application ... then wet sand ..... as a smoothe hull will better shed the slime when the boat moves through the water.
Most of my fellow racers use sprayed-on "Balto-plate" in the Ches. I use Micron CSC.
The real "slime-time" occurs in late September when the bay ''turns-over'' all its nutrients .... and sorry but at that time of year you have to scrub.

Interlux has a new product called Ultra with ummmmmm biotex? biocide? biosomething.... That claims to eliminate slime. I was thinking of trying that instead of the usual copolymer. I think it''s new, which explains some of the sale pricing I saw in West Marine a couple weeks ago.
