§ 1067. Substitute lights for power-driven vessels, 

 power-driven vessels towing or pushing other ves- 

 sels, vessels under oars or sails, vessels being 

 towed or pushed ahead, and rowing boats (Rule 7). 



Power-driven vessels of less than 65 feet in length, 

 vessels under oars or sails or less than 40 feet In 

 length, and rowing boats, when under way shall not 

 be required to carry the lights prescribed in sections 

 1062, 1063, and 1065 of this title, but if they do not 

 carry them they shall be provided with the following 

 lights — 



(a) Power-driven vessels of less than 65 feet in 

 length, except as provided in subsections (b) and 

 (c) of this section, shall carry — 



(i) In the forepart of the vessel, where it can 

 best be seen, and at a height above the gunwale 

 of not less than 9 feet, a white light constructed 

 and fixed as prescribed in section 1062(a) (i) of 

 this title and of such a character as to be visible 

 at a distance of at least 3 miles. 



(ii) Green and red sidelights constructed and 

 fixed as prescribed in section 1062(a) (iv) and (v) 

 of this title, and of such a character as to be visible 

 at a distance of at least 1 mile, or a combined 

 lantern showing a green light and a red light 

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

 the beam on their respective sides. Such lantern 

 shall be earned not less than 3 feet below the 

 white light. 



(b) Power-driven vessels of less than 65 feet in 

 length when towing or pushing another vessel shall 

 carry — 



(1) In addition to the sidelights or the combined 

 lantern prescribed in subsection (a)(ii) of this 

 section two white lights in a vertical line, one over 

 the other not less than 4 feet apart. Each of 

 these lights shall be of the same construction and 

 character as the white light prescribed In subsec- 

 tion (a) (i) of this section and one of them shall 

 be carried in the same position. In a vessel with 

 a single mast such lights may be carried on the 

 mast.

 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) Power-driven vessels of less than 40 feet in 

 length may carry the white light at a less height 

 than 9 feet above the gunwale but it shall be car- 

 ried not less than 3 feet above the sidelights or the 

 combined lantern prescribed in subsection (a)(ii) 

 of this section. 



(d) Vessels of less than 40 feet in length, under 

 oars or sails, except as provided in subsection (f ) of 

 this section, shall, if they do not carry the side- 

 lights, carry, where it can best be seen, a lantern 



showing a green light on one side and a red light on 

 the other, of such a character as to be visible at a 

 distance of at least 1 mile, and so fixed that the 

 green light shall not be seen on the port side, nor 

 the red light on the starboard side. Where it is not 

 possible to fix this light, it shall be kept ready for 

 immediate use and shall be exhibited in sufficient 

 time to prevent collision and so that the green light 

 shall not be seen on the port side nor the red light 

 on the starboard side. 



(e) The vessels referred to in this section when 

 being towed shall carry the sidelights or the com- 

 bined lantern prescribed in subsections (a) or (d) 

 of this section, as appropriate, and a stem light as 

 prescribed in section 1070 of this title, or, except the

 scribed in subsection (b) (ii) of this section. When 

 being pushed ahead they shall carry at the forward 

 end the sidelights or combined lantern prescribed 

 in subsections (a) or (d) of this section, as appro- 

 priate, provided that any number of vessels referred 

 to in this section when pushed ahead in a group 

 shall be lighted as one vessel under this section un- 

 less the overall length of the group excee(is 65 feet 

 when the provisions of section 1065 (t) of this title 

 shall apply.

 shapes prescribed in sections 1064(a) and 1071(e) 

 of this title and the size of their day signals may be

 (c) of this title. (Pub. L. 88-131, § 4, Sept. 24, 1963,

(i) Shall carry a white light at the masthead 

 at a height of not less than 20 feet above the hull, 

 visible all round the horizon at a distance of at 

 least 3 miles and at a distance of 8 feet below it 

 a red light similar in construction and character. 

 If such a vessel is of less than 65 feet in length
