If you mean what colour the lights are then it's simple enough to remember - Port lights are red (just like the drink Port) and starboard lights are green. It's a bit harder to remember which is left and right but this may help - look towards the bow (pointed end of the ship), Port is the left hand side of the ship - both the words left and port have four letters. It's also important to remember that port and starboard refer to the ship's left and right sides not yours so port remains the left side of the ship regardless of your own physical position on it or the direction you are actually facing. Hope I've explained that okay.
Just like on a boat, red to port & green to starboard. You also need a white light at the rear.
Head lights, port, starboard and stern lights (on 28' pontoon boat).
Port is red, starboard is green.A rhyme is "wine is red and there's little left in the bottle."
Port to port is the preferred method passage in most cases, however it is not always possible or practical. Also in crossing situations it maybe unsafe to arrange a port to port passage. I have seen plenty of acceptable starboard to starboard passages.
Green. So at a distance you know the direction of travel of the vessel.orAny lighting on the port (left) side of a ship.Port is Red, Starboard is Green
A sailing vessel is approaching head-on. You must give way. The lights that are seen from the front of a small boat are red and green. They signify the port and starboard sides of the ship. Red is for the port (left) side and green is the starboard (right) side.
Submarines only use very few lights: 1. Bow and Stern (rudder) lights - the Bow light is contained withing the jackstaff, and is only used in port while moored or anchored. The Rudder light is used while underway surfaced, along with the Port/Starboard lights.l 2. Port and Starboard Navigation lights - like all vessels, submarines use Port (Red) and Starboard (Green) navigation lights, which are located on the submarine's sail/fairwater. 3. Yellow Flashing Light - Submarines traveling on the surface at night use a raised mast with a flashing yellow beacon. The beacon, along with the other navigation lights, tell other ships that the vessel is a submarine, and which direction it's headed. 4. Security lights - Mounted on the sail in port, they are used as safety/security lights while moored or anchored.
