Section 250-011-0040 - Division Definitions

(1) "All-Round Light is a light showing an unbroken light over an arc of the 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.

(18) "Whistle" is any sound signaling appliance capable of producing the prescribed blasts and which complies with current U.S. Coast Guard specifications.

(19) "Wing-In-Ground (WIG) craft" is a multimodal craft which, in its main operational mode, flies in close proximity to the surface by utilizing surface-effect action.
