Boats not engaged in diving operations shall remain at least 100 feet from areas displaying the diver down flag, or boats displaying the code flag alpha. Persons engaged in barefoot, jump, or trick skiing may elect to wear, at their own risk, a wetsuit designed specifically for that activity. Inflatable life jackets are not acceptable for anyone towed behind a boat. In addition to the operator, a competent observer must be in the boat in a position to observe the progress of the person being towed. A competent observer is a person who has the ability to assess when a skier is in trouble, knows and understands the water-skiing hand signals, and is capable of helping a skier.
Skiers count in the boat's total capacity.
Skiing is prohibited between sunset and sunrise. If boat traffic permits, skiers may start from the shore or dock. Skiers may not be returned to the shore or dock under power. Mooring or drifting within 100 feet of a ski ramp or jump while it is in use is prohibited. It is legal to tow more than one skier except where locally prohibited.
