Rules of the Road · Inland Lights Differences
A composite unit (a tug and a barge made up as a single vessel) on inland waters must show:
- AThe lights of a towing vessel and separately the lights of a vessel being pushed
- BThe lights of a single power-driven vessel and, if over 50 meters, two masthead lights✓ Correct
- COne masthead light and a special flashing yellow light at the bow of the barge
- DThree masthead lights and the sidelights of the combined unit
Explanation
Under Inland Rule 24(b), a composite unit is treated as a single power-driven vessel. It shows masthead lights (one if under 50 m, two if 50 m or more in length), sidelights, and a sternlight. No special flashing light is required because it is a composite unit, not a separate pushed vessel.
Authority: Inland Rule 24(b)
