If your recreational craft is normally kept in the water
(regardless of whether it is trailerable or not), an appropriate anti-fouling
coating system and good maintenance are the best way of preventing
biofouling accumulation. If you regularly operate recreational craft
in both marine and fresh waters, this may help to reduce the accumulation
of biofouling (many marine fouling species do not easily survive in
fresh or brackish water and vice versa) however, a good maintenance
regime is still essential.
