At sea, one can pull a rope under your forefoot and saw it back and forth across the hull working your way back to the keel, then doing the same from the keel to the skeg. Doesn't get everything, but removes a lot, if the growth is thick and heavy.

Both somewhat effective methods if you don't care about the environment or your anti fouling paint.
