Rule 571-37.6 - Lights on vessels

The following lights shall be required on all vessels.

(1)Vessels at anchor. A vessel at anchor shall exhibit between the hours of sunset and sunrise:

1.In the forepart, a white light to show 360 degrees around the horizon or one ball; and

2.At or near the stern and at a lower level than the light prescribed in paragraph "1" above, a white light to show 360 degrees around the horizon.

A vessel of less than 50 meters in length may exhibit a white light to show 360 degrees around the horizon instead of the lights prescribed in this subrule.

(2)Vessels not powered by motor or sail. All vessels not powered by motor or sail and not at anchor shall exhibit a white light to show 360 degrees around the horizon that is visible from at least one mile under clear conditions between the hours of sunset and sunrise when operated on natural lakes, Corps of Engineers impoundments, border rivers excluding border portions of the Big Sioux and Des Moines rivers, and impoundments on inland rivers. If the white light is partially obscured due to the nature of the craft, an additional white light must be shown in sufficient time to prevent collision. When operated on bodies of water other than those listed in this subrule, all vessels not powered by motor or sail and not at anchor shall have in possession a white light to be used when necessary between the hours of sunset and sunrise.

This rule is intended to implement Iowa Code section 462A.3.
