Definitions

(a) "Masthead light" means a white light place over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel

(b) "sidelights" means a green light on the starboard side and a red light on the port side each showing an unbroken light over an arc of the horizon of 112.5 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on its respective side. In a vessel of less than 20 meters in length the side lights maybe combined in one lantern carried on the fore and aft centerline of the vessel.

(c) "Sternlight" means a white light placed as nearly as practical at the stern showing an unbroken light over an arc of 135 degrees and so fixed as to show the light 67.5 degrees from right aft on each side of the vessel.

(d) "Towing light" means a yellow light having the same characteristics as the "sternlight" defined in paragraph (c) of this rule.

(e) "All-around light" means a light showing an unbroken light over an arc of the horizon of 360 degrees.

(f) "Flashing light" means a light flashing at regualr intervals at a frequency of 120 flashes per minute.

Whew! That was a lot of typing! See Rule 21-Inland for additional lights pertaining to inland rules.
