- Nóta Vessels (boats and ships) must have navigation lights so that other vessels can see if there is a danger of collision and take action to avoid it. These lights also help to determine the size, relative angle and (sometimes) type of vessel. All vessels show a green light on the right side of the ship (starboard) and a red light on the left (port) side, as well as a stern light (behind or astern). The red and green lights mentioned are called sidelights. Ships must also show at least one masthead (on the high mast) light (two for larger vessels). All lights have well defined angles through which they must be visible. Outside of these angles, the lights cannot be seen.
