40 LAWS GOVERNING MARINE INSPECTION 



additional all-round wliite lig:lit 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 outlying gear. This additional white light shall be 

 placed at a height not exceeding that of the white light prescribed 

 in section (c) (i) and not lower than the sidelights. 



(g) In addition to the lights which they are required by this Rule 

 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 approaching vessel, in such a way as not to embarrass 

 other vessels. They may also use working lights but fishermen shall 

 take into account that specially bright or insufficiently screened work- 

 ing lights may impair the visibility and distinctive character of the 

 lights prescribed in this Rule. 



(h) By day vessels when engaged in fishing shall indicate their 

 occupation by displaying where it can best be seen a black shape con- 

 sisting 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 

 Rule 1(c) (xlv). 



33 U.S.C. 1070 (Rule 10) 



(a) Except where otherwise provided in these rules, a vessel when 

 under way shall cany at her stem 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 67i/^ 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 

 (he 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. 



33 U.S.C. 1071 (Rule 11) 



(a) A vessel of less than 150 feet in length, when at anchor, shall 

 carry in the forepart of the vessel, where it can best be seen, a white 

 light visible all round the horizon at a distance of at least 2 miles. 

 Such a vessel may also carry a second white light in the position pre- 

 scribed in section (b) of this Rule but shall not be required to do so. 

 The second white light, if earned, shall be visible at a distance of at 

 least 2 miles and so placed as to be as far as possible visible all round 

 the horizon.
