Colorado law designates the following dangerous operating practices as illegal.
Riding on Bow or Gunwales is allowing motorboat passengers to ride on the bow, decking, gunwales, or any other position where there is a danger of falling overboard. These restrictions do not apply when the motorboat is being moored or anchored.
Overloading or Overpowering is loading or powering the vessel beyond the safe load and power limits, taking into consideration the weather and other operating conditions. The safe load and power limits for most vessels are shown on the capacity plate installed by the vessel manufacturer.
