What lights are required on a boat at 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-degree circle.
Whenever you are operating between sunset and sunrise, or in other times of restricted visibility, such as in fog or rain, you need to display the appropriate navigation lights so that other boats can see you and take the appropriate action to avoid a collision.
What lights are required on a boat under 23 feet?
Vessels Under Oars or Paddles and Sailboats Under 23 FT
If you are operating a sailboat that is less than 23 feet or 7 meters in length, you are only required to display a white light, such as a lantern or a flashlight, when operating between sunset and sunrise or during periods of restricted visibility.
