Rules to play Knee Boarding
Under California law, the display of a ski flag is mandatory to indicate a skier in the water, or a ski,
a line, or similar equipment in the immediate area. The display of the ski flag does not in itself restrict
the use of the water, but warns boaters operating in the area to exercise caution.
Boaters who see a red or orange flag being displayed should be on the lookout for a skier or equipment
in the water.
