Course Outline

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 (if vessel is less than 39.4 feet long) 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.
  • No other lights (including docking lights) may be used which could be mistaken for or interfere with those required above.
