  • Boats under 16 feet: These boats must carry a white all-around light visible from all directions.
  • Boats 16 to 26 feet: These boats must carry a white all-around light and a red or green side light. The side light should be visible from a distance of at least one mile.
  • Boats 26 to 40 feet: In addition to the lights required for shorter boats, these vessels must also carry a white stern light.
  • Boats 40 feet and above: These boats must carry all the lights required for shorter boats, plus additional lights as specified in the U.S. Coast Guard's Navigation Rules.
