she is unable to get out of the way of approaching vessels, shall carry, 

 in lieu of the lights prescribed in Rule 2 (a) (i) and (ii), or Rule 7(a) 

 (i), three 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. The highest and lowest of 

 these lights shall be red, and the middle light shall be white, and they 

 shall be of such a character as to be visible all round the horizon at a 

 distance of at least 2 miles. By day, she shall carry in a vertical line 

 one over the other not less than 6 feet apart, where they can best be 

 seen, three shapes each not less than 2 feet in diameter, of which the 

 highest and lowest shall be globular in shape and red in colour, and 

 the middle one diamond in shape and white. 



(d) (i) A vessel engaged in minesweeping operations shall carry 

 at the fore truck a green light, and at the end or ends of the fore yard 

 on the side or sides on wliich danger exists, another such light or 

 lights. These lights shall be carried in addition to the light pre- 

 scribed in Rule 2(a) (i) or Rule 7(a)(i),as appropriate, and shall be 

 of such a character as to be visible all round the horizon at a distance 

 of at least 2 miles. By day she shall carry black balls, not less than 

 2 feet in diameter, in the same position as the green lights. 



(ii) the showing of these lights or balls indicates that it is danger- 

 ous for other vessels to approach closer than 3,000 feet astern of the 

 minesweeper or 1,500 feet on the side or sides on which danger exists. 



(e) The vessels and seaplanes referred to in this Rule, when not 

 making way through the water, shall show neither the coloured 

 sidelights nor the stem light, but when making way they shall show 

 them. 



(f ) The lights and shapes prescribed in this Rule are to be taken 

 by other vessels and seaplanes as signals that the vessel or seaplane 

 showing them is not under command and cannot therefore get out of 

 the way. 



(g) These signals are not signals of vessels in distress and requiring 

 assistance. Such signals are contained in Rule 31.

 never carry. They shall also carry stern lights as prescribed in Rule

 Rule 3(b). 



(b) In addition to the lights prescribed in section (a)^ a sailing 

 vessel may carry on the top of the foremast two lights in a vertical 

 line one over the other, sufficiently separated so as to be clearly dis- 

 tinguished. The upper light shall be red and the lower light shall be 

 green. Both lights shall be constructed and fixed as prescribed in 

 Rule 2 (a) (i) and shall be visible at a distance of at least 2 miles.
