No vessel other than the tending vessel shall be operated within one hundred feet of a red flag with a diagonal white bar which, when displayed on the water or from a boat, indicates underwater diving, or a designated course for racing shells but no such flag shall be placed so as to deny access or use of any boathouse, wharf, harbor, bay, channel or navigable waterway. 2. Except as provided in section forty-five-cc of this part, no vessel shall be operated within one hundred feet of the shore, a dock, pier, raft, float or an anchored or moored vessel at a speed exceeding five miles per hour, unless such vessel is being operated near such shore, dock, float, pier, raft, or anchored vessel for the purpose of enabling a person engaged in water skiing to take off or land. 3.
