Navigation Lights for Small Boats

Small boat operators should make sure that their boats are equipped with the proper navigation lights and use these lights during the following conditions:

When away from the dock between sunset and sunrise.
During periods of restricted visibility such as fog or heavy rain.
No other lights that may be mistaken for required navigation lights may be exhibited. Also alue or red flashing lights are restricted to use by law enforcement vessels only.

The required navigation lights differ depending on the type and size of your vessel. For other configurations and requirements for larger vessels, see the U.S. Coast Guard's Navigation Rules.

Power-Driven Vessels Less Than 65.6 Feet Long When Underway
Power-driven vessels include sailboats operating under engine power. The required lights are:
Red and green sidelights visible from a distance of at least two miles away, or if less than 39.4 feet (12 meters) long, at least one mile away, on a dark, clear night. An all-round white light if vessel is less than 39.4 feet long or both a masthead light and a sternlight. These lights must be visible from a distance of at least two miles away on a dark, clear night. The all-round white light or the masthead light must be at least 3.3 feet (one meter) higher than the sidelights.

Unpowered Vessels When Underway
Unpowered vessels are sailing vessels or vessels that are rowed.
An alternative to the sidelights and sternlight is a combination red, green, and white light, which must be exhibited near the top of the mast.

If less than 65.6 feet long, the required lights are:
Red and green sidelights visible from a distance of at least two miles away, or if less than 39.4 feet long, at least one mile away, on a dark, clear night. A sternlight visible from a distance of at least two miles away. If less than 23.0 feet (7 meters) long, these vessels should:

If practical, exhibit the same lights as required for unpowered vessels less than 65.6 feet in length. If not practical, have on hand at least one lantern or flashlight shining a white light.

All Vessels When Not Underway
All vessels are required to display a white light visible in all directions whenever they are moored or anchored outside a designated mooring area between sunset and sunrise.
