Today we finally get to SAILING LIGHTS!

First we look at a SAILING vessel underway that must have SIDELIGHTS and STERN LIGHT. If the sailing vessel is under 20 meters then it is okay to combine to combine SIDELIGHTS and STERN LIGHT into one light at or near the top of the mast. Another possibility is having one all around PORT (RED) and STARBOARD (GREEN) light in the configuration below.
