34 LAWS GOVERNING MARINE INSPECTION 



structed 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 1121/^ degrees (10 points) on each side of the vessel, that is, 

 from right ahead to 221/^ 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. 



(ii) Either forward or abaft the white light prescribed in 

 sub-section (i) a second white light similar in construction and 

 character 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. 



(iii) 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 however that the light need not be placed at a greater 

 height above the hull than 40 feet. In all circumstances the light 

 or lights, as the case may be, shall be so placed as to be clear of 

 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 1121/^ degrees 

 (10 points of the compass) , so fixed as to show the light from right 

 ahead to 221/^ 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 1121/^ degrees (10 

 points of the compass), so fixed as to show the light from right 

 ahead to 22i^ 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) A seaplane under way on tlie water shall carry — 



(i) 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. 



(ii) On the right or starboard wing tip a green light, so con- 

 structed 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. 



(iii) 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 110 degrees
