TOWING
A power-driven vessel when towing shall exhibit:
two masthead lights in a vertical line. When the length of the tow, measuring from the stern of the towing vessel to the after end of the tow exceeds 200 metres, three such lights in a vertical line;
sidelights;
a sternlight;
a towing light in a vertical line above the sternlight;
when the length of the tow exceeds 200 metres, a diamond shape where it can best be seen.
Towing an inconspicuous, partly submerged object ... 👇
An inconspicuous, partly submerged vessel or object, or combination of such vessels or objects being towed, shall exhibit:
if it is less than 25 metres in breadth, one all-round white light at or near the forward end and one at or near the after end except that dracones need not exhibit a light at or near the forward end;
if it is 25 metres or more in breadth, two additional all-round white lights at or near the extremities of its breadth;
if it exceeds 100 metres in length, additional all-round white lights between these lights so that the distance between the lights shall not exceed 100 metres;
a diamond shape at or near the aftermost extremity of the last vessel or object being towed and if the length of the tow exceeds 200 metres an additional diamond shape where it can best be seen and located as far forward as is practicable.
Pushing from ahead or towing alongside 👇
When a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit they shall be regarded as a power-driven vessel and exhibit the normal lights.
A power-driven vessel when pushing ahead or towing alongside, except in the case of a composite unit, shall exhibit:
two masthead lights in a vertical line;
sidelights;
a sternlight.
A vessel or object being towed shall exhibit:
sidelights;
a sternlight;
when the length of the tow exceeds 200 metres, a diamond shape where it can best be seen.
Provided that any number of vessels being towed alongside or pushed in a group shall be lighted as one vessel,
a vessel being pushed ahead, not being part of a composite unit, shall exhibit at the forward end, sidelights;
a vessel being towed alongside shall exhibit a sternlight and at the forward end, sidelights.
