Lights Required for Motorboats Less Than 39.4 Feet Long When Underway
If less than 39.4 feet long, these vessels must exhibit the lights as shown in Figure 1. Remember, motorboats include sailboats operating under power.
The required lights are:
- Red and green sidelights visible from a distance of 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 and sternlight) must be visible from all directions in a 360° circle.
