Q

INLAND ONLY Which light(s) shall be shown at night on a moored barge which reduces the navigable width of any channel to less than 80 meters?

🔍 Key Concepts

• INLAND ONLY barge lighting requirements in 33 CFR Part 88 (Annex V – Inland only) • Difference between moored barges and barges being pushed or towed • Meaning and typical use of red obstruction lights vs white all‑round lights on inland waters

💭 Think About

• Ask yourself: When a barge is moored in or near a channel and makes the channel effectively narrower, what is the primary purpose of the lights it must show at night? Warning of an obstruction, or indicating a vessel underway? • Look at each option and decide: Which light configuration is normally associated with towing astern? Which is associated with fixed obstructions or dredging operations? Which is associated with a simple moored barge? • Think about the phrase "unobstructed all‑round" in the regulations: how many such lights and where would they be placed on a barge that is lying still and could be hit from either end?

✅ Before You Answer

• Verify in 33 CFR 88.13–88.15 (Inland only – barge lighting) what is required for barges moored in or near a fairway that reduce the navigable width below a certain distance. • Confirm which option describes all‑round white lights rather than colored (red/yellow) lights used for special situations like dredging or towing. • Make sure the chosen option would clearly mark the ends of the obstruction to navigation so that an approaching vessel from either direction can safely pass.
