381.21 OPERATION IN RESTRICTED AREAS.
   (a)   No person shall operate a vessel 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 vessels are prohibited.
 
   (b)   No person shall operate a vessel at greater than idle speed or at a speed that creates a wake within 300 feet of 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. This section does not apply to any area designated by the Chief of the Division of Watercraft unless it is marked by a buoy or sign as a no wake or idle speed area.
 
   (c)   No person shall operate a vessel in any area of restricted or controlled operation in violation of the designated restriction.
 
   (d)   No person shall operate a vessel within 300 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. 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 vessel.
   Markings on buoys designating areas of restricted or controlled operation shall be so spaced as to show all around the horizon. Lineal spacing between such buoys shall be such that under normal conditions of visibility any such buoy shall be readily visible from the next adjacent buoy. No colors or symbols, except as provided for in rules of the Chief of the Division of Watercraft, shall be used on buoys or signs 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.
 
   (f)   No person shall operate or permit any vessel to be operated in violation of this section.
