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.
