Vessel Lights

Navigation lights are presented in two formats, one organized by vessel type and the other organized by color pattern. The latter is a vast collection of every possible combination of lights by color (ie red only; red and white only; red, white and green only, etc). Each is then identified by simply rolling the cursor over the light pattern.

There is also a separate section that lists all the lights that appear in the USCG Nav Rules exam diagram books. Also included are special sections that list US Navy vessel light options, as well as the modifications of the Nav Rules used in Canadian waters.
