 the port side nor the red light on the starboard 

 side. She shall also carry the Stern light pre- 

 scribed in section 1070 of this title. 



(Hi) Shall show one or more flare-up lights at 

 Intervals not exceeding ten minutes. 



(c) A pilot-vessel when engaged on pilotage duty 

 and not under way shall carry the lights and show 

 the flares prescribed in subsections (a) (i) and (iii) 

 or (b) (i) and (iii) of this section, as appropriate, 

 and if at anchor shall also carry the anchor lights 

 prescribed in section 1071 of this title. 



(d) A pilot-vessel when not engaged on pilotage 

 duty shall show the lights or shapes for a similar 

 vessel of her length. (Pub. L. 88-131, § 4, Sept. 24, 

 1963. 77 Stat. 200.) 



§1069. Fishing vessels; trawling vessels; fishing ves- 

 sels by day (Rule 9). 



(a) Pishing vessels when not engaged in fishing 

 shall show the lights or shapes for similar vessels 

 of their length. 



(b) Vessels engaged in fishing, when under way or 

 at anchor, shall show only the lights and shapes 

 prescribed in this section, which lights and shapes 

 shall be visible at a distance of at least 2 miles. 



(0) (i) Vessels when engaged in trawling, by which 

 is meant the dragging of a dredge net or other ap- 

 paratus through the water, shall carry two lights in 

 a vertical line, one over the other, not less than 4 

 feet nor more than 12 feet apart. The upper of 

 these lights shall be green and the lower light white 

 and each shall be visible all round the horizon. 

 The lower of these two lights shall be carried at a 

 height above the sidelights not less than twice the 

 distance between the two vertical lights. 



(ii) Such vessels may in addition carry a white 

 light similar in construction to the white light pre- 

 scribed in section 1062(a) (i) of this title but such 

 light shall be carried lower than and abaft the all- 

 round green and white lights. 



(d) Vessels when engaged in fishing, except ves- 

 sels engaged in trawling, shall carry the lights pre- 

 scribed in subsection (c) (i) of this section except 

 that the upper of the two vertical lights shall be 

 red. Such vessels if of less than 40 feet in length 

 may carry the red light at a height of not less than 

 9 feet above the gunwale and the white light not 

 less than 3 feet below the red light. 



(e) Vessels referred to in subsections (c) and (d) 

 of this section, when making way through the water, 

 shall carry the sidelights or lanterns prescribed in 

 section 1062(a) (iv) and (v) or section 1067 (a) (ii)

 not making way through the water they shall show 

 neither the sidelights nor the stern light. 



(f) Vessels referred to in subsection (d) of this 

 section with outlying gear extending more than 500 

 feet horizontally into the seaway shall carry an addi- 



tional all-round white light at a horizontal distance 

 of not less than 6 feet nor more than 20 feet away 

 from the vertical lights in the direction of the out- 

 lying gear. This additional white light shall be 

 placed at a height not exceeding that of the white 

 light prescribed in subsection (c)(i) of this section 

 and not lower than the sidelights. 



(g) In addition to the lights which they are re- 

 quired by this section to carry, vessels engaged in 

 fishing may, if necessary in order to attract the 

 attention of an approaching vessel, use a flare-up 

 light, or may direct the beam of their searchlight 

 in the direction of a danger threatening the ap- 

 proaching vessel, in such a way as not to embarrass 

 other vessels. They may also use working lights 

 but fisherman shall take into account that specially 

 bright or insufficiently screened working lights may 

 impair the visibility and distinctive character of 

 the lights prescribed in this section. 



(h) By day vessels when engaged in fishing shall 

 indicate their occupation by displaying where It 

 can best be seen a black shape consisting of two 

 cones each not less than 2 feet in diameter with their 

 points together one above the other. Such vessels 

 if of less than 65 feet in length may substitute a 

 basket for such black shape. If their outlying gear 

 extends more than 500 feet horizontally into the 

 seaway vessels engaged in fishing shall display in 

 addition one black conical shape, point upwards, 

 in the direction of the outlying gear. 



Note. — Vessels fishing with trolling lines are not 

 "engaged in fishing" as defined in section 1061(c) 

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

 1963. 77 Stat. 201.) 



§ 1070. Stern and tail lights (Rule 10). 



(a) Except where otherwise provided in sections 

 1061 to 1094 of this title, a vessel when under way 

 shall carry at her stern a white light, so constructed 

 that it shall show an unbroken light over an arc 

 of the horizon of 135 degrees (12 Points of the 

 compass), so fixed as to show the light 67 Vi degrees 

 (6 points) from right aft on each side of the vessel, 

 and of such a character as to be visible at a distance 

 of at least 2 miles. 



(b) In a small vessel, if it is not possible on 

 account of bad weather or other sufficient cause 

 for this light to be fixed, an electric torch or a 

 lighted lantern showing a white light shall be kept 

 at hand ready for use and shall, on the approach of 

 an overtaking vessel, be shown in sufficient time to 

 prevent collision. 



(c) A seaplane on the water when under way 

 shall carry on her tail a white light, so constructed 

 as to show an unbroken light over an arc of the 

 horizon of 140 degrees of the compass, so fixed as 

 to show the light 70 degrees from right aft on each 

 side of the seaplane, 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. 202.) 



§1071. Vessels and seaplanes at anchor or aground
