LIGHTS AND SHAPES 

 § 1062. Requirements when under way (Rule 2). 

 (a) Power-driven vessels. 



A power-driven vessel when under way shall 

 carry — 



(i) On or in front of the foremast, or if a 

 vessel without a foremast then in the forepart 

 of the vessel, a white light so constructed as to 

 show an unbroken light over an arc of the horizon 

 of 225 degrees (20 points of the compass), so 

 fixed as to show the light 112'2 degrees (10 points) 

 on each side of the vessel, that is. from right 

 ahead to 22 '/2 degrees (2 points) abaft the beam 

 on either side, and of such a character as to be 

 visible at a distance of at least 5 miles. 



(11) Either forward or abaft the white light 

 prescribed In clause (i) of this subsection a second 

 •white light similar in construction and char- 

 acter to that light. Vessels of less than 150 feet 

 In length shall not be required to carry this second 

 white light but may do so. 



(ill) These two white lights shall be so placed in 

 a line with and over the keel that one shall be 

 at least 15 feet higher than the other and in such 

 a position that the forward light shall always be 

 shown lower than the after one. The horizontal 

 distance between the two white lights shall be at 

 least three times the vertical distance. The lower 

 of these two white lights or, if only one is carried, 

 then that light, shall be placed at a height above 

 the hull of not less than 20 feet, and, if the breadth 

 of the vessel exceeds 20 feet, then at a height 

 above the hull not less than such breadth, so how- 

 ever that the light need not be placed at a greater 

 height above the hull than 40 leet. In all cir- 

 cumstances the light or lights, as the case may be. 

 shall be so placed as to be clear nf and above all 

 other lights and obstructing superstructures. 



(iv) On the starboard side a green light so 

 constructed as to show an unbroken light over 

 an arc of the horizon of 112 !'2 degrees (10 points 

 of the compass), so fixed as to show the light 

 from right ahead to 22 ',2 degrees (2 points) abaft 

 the beam on the starboard side, and of such a 

 character as to be visible at a distance of at least 

 2 miles. 



(V) On the port side a red light so constructed 

 as to show an unbroken light over an arc of the 

 horizon of 112'/2 degrees (10 points of the com- 

 pass), so fixed as to show the light from right 

 ahead to 22 1/2 degrees (2 points) abaft the beam 

 on the port side, and of such a character as to 

 be visible at a distance of at least 2 miles. 



(vi) The said green and red sidelights shall be 

 fitted with, inboard screens projecting at least 

 3 feet forward from the light, so as to prevent 

 these lights from being seen across the bows. 



(b) Seaplanes. 

 A seaplane under way on the water shall carry — 

 (1) In the forepart amidships where it can best 

 be seen a white light, so constructed as to show 

 an unbroken light over an arc of the horizon 

 of 220 degrees of the compass, so fixed as to show 

 the light 110 degrees on each side of the seaplane, 

 namely, from right ahead to 20 degrees abaft 

 the beam on either side, and of such a character 

 as to be visible at a distance of at least 3 miles. 

 (li) On the right or starboard wing tip a green 

 light, so constructed as to show an unbroken 

 light over an arc of the horizon of 110 degrees of 

 the compass, so fixed as to show the light from 

 right ahead to 20 degrees abaft the beam on the 

 starboard side, and of such a character as to be 

 visible at a distance of at least 2 miles. 



(lii) On the left or port wing tip a red light, 

 so constructed as to show an unbroken light over 

 an arc of the horizon of 1 10 degrees of the com- 

 pass, so fixed as to show the light from right 

 ahead to 20 degrees abaft the beam on the port 

 side, and of such a character as to be visible at 

 a distance of at least 2 miles. 



(Pub. L. 88-131, § 4, Sept. 24, 1963, 77 Stat. 196.) 



§ 1063. Towing or pushing other vessels or seaplanes 

 (Rule 3). 



(ai A power-driven vessel when towing or push- 

 ing another vessel or seaplane shall, in addition to 

 her sidelights, carry two white lights In a vertical 

 line one over the other, not less than 6 feet apart, 

 and when towing and the length of the tow. measur- 

 ing from the stern of the towing vessel to the stem 

 of the last vessel towed, exceeds 600 feet, shall carry 

 three white lights in a vertical line one over the 

 other, so that the upper and lower lights shall be 

 the same distance from, and not less than 6 feet 

 above or below, the middle light. Each of these 

 lights shall be of the same construction and char- 

 acter and one of them shall be carried in the same 

 position as the white light prescribed in section 1062 

 (a) (1) of this title. None of these lights shall be 

 carried at a height of less than 14 feet above the 

 hull. In a vessel with a single maol, such lights 

 may be carried on the mast. 



lb) The towing vessel shaU also show either the 

 stern light prescribed In section 1070 of this title 

 or in lieu of that light a small white light abaft 

 the funnel or aftermast for the tow to steer by, but 

 such light shall not be visible forward of the beam. 



(c) Between sunrise and sunset a power driven 

 vessel engaged in towing, if the length of tow ex- 

 ceeds 600 feet, shall carry, where it can best be 

 seen, a black diamond shape at least 2 feet In 

 diameter. 



(d) A seaplane on the water, when towing one 

 or more seaplanes or vessels, shall carry the lights 

 prescribed in section 1062(b) (i), (ii), and (iii) of 

 this title; and, in addition, she shall carry a sec-
