It's the Law: Required Equipment

Navigation Lights

The required navigation lights must be displayed between sunset and sunrise and during periods of restricted visibility.

Power-Driven Vessels When Underway

Fig.1: Navigation lights on vessels less than 65.6 ft.

If less than 65.6 feet long, these vessels must exhibit the lights as shown in Figure 1. Remember, 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 long, at least one mile away—on a dark, clear night.
  • An all-round white light 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 higher than the sidelights.

 

Unpowered Vessels When Underway

Unpowered vessels are sailboats or vessels that are paddled, poled, or rowed.

  • If between 23.0 feet long and 65.6 feet long, vessels must exhibit the lights as shown in Figure 2. The required lights are:
  • Red and green sidelights visible from at least two miles away—or if less than 39.4 feet long, at least one mile away.
  • A sternlight visible from at least two miles away.

Fig.2: Sailboats with combination sidelights and sternlight AND with combination red, green, and white light at top of mast.

If less than 23.0 feet long 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 as in Figure 3.

All Vessels When Not Underway

All vessels are required to display a white light visible for one mile from all directions whenever they are anchored away from a dock between sunset and sunrise.
