			 horizon of 360 degrees.
(2)
			 "Flashing Light" is a light flashing at regular intervals at a frequency of 120
			 flashes or more per minute.
(3)
			 "In sight" is when one vessel can be observed visually by the other.
(4) "Masthead Light" is a white light placed
			 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, except
			 that on a vessel of less than 12 meters in length the masthead light shall be
			 placed as nearly as practicable to the fore and aft centerline of the vessel.
(5) "Power-driven vessel" is any
			 vessel propelled by machinery.
(6)
			 "Prolonged blast" is a blast of from four to six second's duration.
(7) "Restricted visibility" is any condition
			 in which visibility is restricted by fog, mist, falling snow, heavy rainstorms,
			 sandstorms, or any other similar causes.
(8) "Sailing vessel" is any vessel under sail
			 provided that propelling machinery, if fitted, is not being used.
(9) "Seaplane" includes any aircraft designed
			 to maneuver on the water.
(10)
			 "Short blast" is a blast of about one second's duration.
(11) "Sidelights" is 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. On a
			 vessel of less than 20 meters in length the sidelights may be combined in one
			 lantern carried on the fore and aft centerline of the vessel, except that on a
			 vessel of less than 12 meters in length the sidelights when combined in one
			 lantern shall be placed as nearly as practicable to the fore and aft centerline
			 of the vessel.
(12) "Special
			 Flashing Light" is a yellow light flashing at regular intervals at a frequency
			 of 50 to 70 flashes per minute, placed as far forward and as nearly as
			 practicable on the fore and aft centerline of the tow and showing on unbroken
			 light over an arc of the horizon of not less than 180 degrees nor more than 225
			 degrees and so fixed as to show the light from right ahead to abeam and no more
			 than 22.5 degrees abaft the beam on either side of the vessel.
(13) "Sternlight" is a white light placed as
			 nearly as practicable at the stern showing an unbroken light over an arc of the
			 horizon of 135 degrees and so fixed as to show the light 67.5 degrees from
			 right aft on each side of the vessel.
(14) "Towing Light" is a yellow light having
			 the same characteristics as the "sternlight" defined in of this rule.
(15) "Vessel" includes every
			 description of water craft, including non-displacement craft and seaplanes,
			 used or capable of being used as a means of transportation on the water.
(16) "Vessel not under command" is
			 a vessel which through some exceptional circumstances is unable to maneuver as
			 required by this section and is therefore unable to keep out of the way of
			 another vessel.
(17) "Vessel
			 restricted in its ability to maneuver" is a vessel which from the nature of its
			 work is restricted in its ability to maneuver as required by this section and
			 is therefore unable to keep out of the way of another vessel; vessels
			 restricted in their ability to maneuver include, but are not limited to:
(a) a vessel engaged in laying, servicing, or
			 picking up a navigation mark, submarine cable, or pipeline;
(b) a vessel engaged in dredging, surveying,
			 or underwater operations;
(c) a
			 vessel engaged in replenishment or transferring persons, provisions, or cargo
			 while underway;
(d) a vessel
			 engaged in the launching of recovery of aircraft;
(e) a vessel engaged in mine clearance
			 operations; and
(f) a vessel
			 engaged in towing operations such as severely restricts the towing vessel and
			 its tow in their ability to deviate from their course.
