Required Lights: Unpowered Sailing Watercraft Less Than 65 Feet When Underway

All unpowered sailing watercraft must exhibit sidelights and a stern light when underway.

If less than 65 feet long, these watercraft must exhibit the lights.

• These watercraft can combine the required sidelights and stern light by carrying one lantern at or near the top of the mast where it can best be seen.
• Additionally, these watercraft may exhibit two all-around lights at or near the top of the mast in a vertical line. In this arrangement, the top light should be red and the lower light should be green. These lights cannot be shown if the combined lantern is used.
