971.11  OPERATION IN RESTRICTED AREAS.
   (a)    No person shall operate a watercraft within or through a designated bathing area or within or through any area which has been buoyed off designating it as an area in which watercraft are prohibited.
   (b)    No person shall operate a watercraft at greater than idle speed or at a speed that creates a wake near any marina, boat docking facility, boat gasoline dock, launch ramp, recreational boat harbor or harbor entrance or within any area buoyed or marked as a no wake area.
   (c)    No person shall operate a watercraft in any area of restricted or controlled operation in violation of the designated restriction.
   (d)    No person shall operate a watercraft within 150 feet of an official diver's flag unless he is tendering the diving operation.
   (e)    All areas of restricted or controlled operation as described in subsection (a) hereof, or as provided for in Ohio R.C. 1547.14 or 1547.61 shall be marked by a buoy or sign designating the restriction. The specific areas described in subsection (b) hereof shall be considered restricted areas without being designated by a buoy or sign. All waters surrounded by or lying between such a buoy or sign and the closest shoreline are thereby designated as an area in which the designated restrictions shall apply in the operation of any watercraft.
   Markings on a buoy or sign designating areas of restricted or controlled operation shall be so spaced as to show all around the horizon. Lineal spacing between such buoys or signs shall be such that under normal conditions of visibility any such buoy or sign shall be readily visible from the next adjacent buoy or sign. No colors or symbols, except as provided for in rules of the Chief of the Division of Watercraft, shall be used for marking closed or controlled areas of boating waters.
   The City is authorized to place such buoys or signs on its waters and may apply to the Chief of the Division of Watercraft for permission to place such buoys or signs on other waters within its territorial limits. (ORC 1547.08)
