LIGHTS & SHAPES
Inland Navigation Rules Act of 1980
Rules 20 through 31
Developed and provided courtesy of Ohio Dept. Natural Resources
Lights on your boat  are for the benefit of other boaters. If properly displayed, your lights indicate the type of vessel, size of vessel, direction of travel, mode of operation (underway vs. anchored), etc.
With that information, the operators of vessels can apply the Nav Rules at night.
Without properly displayed lights, the risk of night boating is greatly increased.
