Required Lights: Motorboats and Sailboats When Underway

If less than 65.6 feet (20 meters) long, all motorboats and sailboats must exhibit the lights. 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 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. On New Mexico state waters, all motorboats regardless of length must have an all-round white light that is higher than the sidelights.
