§ 82.1 Purpose
This part contains the interpretative rules concerning the 72 COLREGS that are adopted by the Coast Guard for the guidance of the public.

§ 82.3 Pushing vessel and vessel being pushed: Composite unit 
Rule 24(b) of the 72 COLREGS states that when a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit, they are regarded as a power-driven vessel and must exhibit the lights under Rule 23. A "composite unit" is interpreted to be a pushing vessel that is rigidly connected by mechanical means to a vessel being pushed so they react to sea and swell as one vessel.
"Mechanical means" does not include the following:
(a) Lines.
(b) Hawsers.
(c) Wires.
(d) Chains.

§ 82.5 Lights for moored vessels
For the purposes of Rule 30 of the 72 COLREGS, a vessel at anchor includes a barge made fast to one or more mooring buoys or other similar device attached to the sea or river floor. Such a barge may be lighted as a vessel at anchor in accordance with Rule 30, or may be lighted on the corners in accordance with 33 CFR 88.13.

§ 82.7 Sidelights for unmanned barges
An unmanned barge being towed may use the exception of COLREG Rule 24(h). However, this exception only applies to the vertical sector requirements.
