The red sidelight is on the port side and the green sidelight is on the starboard side. One way to remember this is to consider that port wine is red, and thus the port sidelight is also red.

The red sidelight is on the port side and the green sidelight is on the starboard side. One way to remember this is to consider that port wine is red, and thus the port sidelight is also red.
Each sidelight is required to shine over an angle of 112.5 degrees, from directly forward, to each respective side of the boat.
The phrase "red, right, returning" can be applied when viewing other boats. If you see a red and a green light on a boat at night and the red light is to the right of the green light, then you know the boat is pointed at you ("returning" to you). This is also true with airplanes.
On sailboats, it is permitted to use a "tricolor light" at the top of the mast to replace the sidelights and sternlight. Use of a tricolor light is only permitted when the boat is sailing and not under motor power. [links]
The stern light is coloured white. A sternlight is a white light placed as closely as practical at the stern shining constantly, affixed in a manner so that the light will shine out at 135 degrees from the back of the boat and affixed to show the light from aft on each side of a pleasure craft.
The arc of the lights and color allows you to determine the direction a vessel is moving. How good are your lights? You should test them to see how visible you might be at night. Whether on a trailer or at the marina, switch on your lights and see how well they can be seen. Walk away from the boat or row away, if you are at anchor or at a mooring, and see how visible the lights are as you move further away. How easy are they to see against the background of lights on shore?

The common abbreviation P.S. (for English postscript, derived from Latin post scriptum) can be viewed as port ("left") and starboard ("right").
It is quite simple. There are four letters in the words PORT and LEFT so you can easily remember that the left side of a boat is the port side. here
Starboard navigation light is green. more
