Every operator of a float is responsible for the wake of that float. In dug sections of the canal system, float speed shall not exceed 10 miles per hour, except within 100 feet of a dock, pier, raft, float, anchored or moored, float speed shall not exceed five miles per hour. In canalized rivers of the canal system, float speed shall not exceed the posted speed or, if there is no posted speed, shall depend on the conditions of traffic but shall not exceed 45 miles per hour, except within 100 feet of a dock, pier, raft, anchored or moored float, speed shall not exceed five miles per hour, unless such float is being operated near such dock, pier, raft, anchored or moored float for the purpose of enabling a person engaged in water skiing to take off or land. In lakes of the canal system, float speed shall depend on the conditions of traffic, except within 100 feet of the shoreline, a dock, pier, raft, anchored or moored float, speed shall not exceed five miles per hour, unless such float is being operated near such dock, pier, raft, anchored or moored float for the purpose of enabling a person engaged in water skiing to take off or land. So far as may be practicable, the rates of speed will be indicated for the various sections at each lock and in no event shall such rates of speed be exceeded. Any operator of a float violating this section shall be subject to a penalty not exceeding $100 for each offense and the lock or bridge at which the float first appears following such violation, may refuse such float passage for a period of not more than six hours.
