Sec. 84.05  Horizontal positioning and spacing of lights.



    (a) Except as specified in paragraph (e) of this section, when two 

masthead lights are prescribed for a power-driven vessel, the horizontal 

distance between them must not be less than one quarter of the length of 

the vessel but need not be more than 50 meters. The forward light must 

be placed not more than one half of the length of the vessel from the 

stem.

    (b) On a power-driven vessel of 20 meters or more in length the 

sidelights shall not be placed in front of the forward masthead lights. 

They shall be placed at or near the side of the vessel.

    (c) When the lights prescribed in Rule 27(b)(i) are placed 

vertically between the forward masthead light(s) and the after masthead 

light(s) these all-round lights shall be placed at a horizontal distance 

of not less than 2 meters from the fore and aft centerline of the vessel 

in the athwartship direction.

    (d) When only one masthead light is prescribed for a power-driven 

vessel, this light must be exhibited forward of amidships. For a vessel 

of less than 20 meters in length, the vessel shall exhibit one masthead 

light as far forward as is practicable.

    (e) On power-driven vessels 50 meters but less than 60 meters in 

length operated on the Western Rivers, and those waters specified in 

Sec. 89.25, the horizontal distance between masthead lights shall not 

be less than 10 meters.
