Required navigation lights differ according to type and size of the boat.

  • Red and green sidelights:

  • Lights must be visible to another boat approaching from the side or head-on.
  • For boats less than 39.4 feet in length, light must be visible from at least one mile on a clear dark night.
  • And either:
  • An all-around white light which must be at least 3.3 feet higher than the sidelights
  • Or, both:
  • A masthead light (white light) that shines forward (located on the mast of a sailboat). Must be used by all boats when operating under engine power.
