Navigation Lights
Navigation lights are not to help you see where you are
going, but rather to help other boats see you, and determine
your direction, length, or activity. All boats underway (not
tied to the dock or at anchor) must display their navigation
lights at all times between sunset and sunrise, and during
periods of restricted visibility.

degrees around

* Some people use the phrase 'port wine is always red' to help
remember that the port sidelight is red, and the starboard sidelight
is green.

The type of lights your boat must have depends on the size
and type of the boat. Power boats must have a masthead
light, side lights, and stern light. If the boat is less than 12
meters (39 ft.) in length, the masthead and stern light may
be combined into one light.
Power boats that are longer than 50 meters (164ft.) must
carry a second masthead light that is aft of and higher
than the first. Smaller power boats may carry the second
masthead light but are not required to do so.
Sail boats must have side lights and stern lights. They do
not have a masthead light. Sail boats less than 20 meters
(65 ft.) may combine the side lights and stern light into one
lantern carried at or near the top of the mast where it can
best be seen. Sail boats, in addition to the side lights and
stern	light,	may	exhibit	at	or	near	the	top	of	the	mast	two	allround lights the upper being red and the lower being green.
