BOTH INTERNATIONAL & INLAND Which vessel may...

🔍 Key Concepts

• Rule 23 – Power-driven vessels underway and Rule 25 – Sailing vessels underway and vessels under oars (Navigation Rules) • Special provisions for combined lanterns (tricolor or all‑round) and when they are allowed by vessel length and vessel type • Difference between lights for sailing vessels, power‑driven vessels, vessels engaged in fishing, and pilot vessels

💭 Think About

• First decide: which rule covers combined sidelights and stern light in a single lantern, and is it for sailing vessels or power‑driven vessels? • Look at each choice and ask: does this vessel’s length and type of operation match the rule that allows a combined lantern? • Check whether special‑duty vessels (fishing, pilot) can replace their normal running lights with a combined lantern, or whether they must carry both normal running lights and additional special lights.

✅ Before You Answer

• Verify the maximum length of a vessel allowed to use a combined sidelights/stern light lantern under the Navigation Rules. • Confirm whether vessels engaged in fishing and pilot vessels are required to display extra lights in addition to standard sidelights and stern light, rather than combining them. • Make sure you distinguish between sailing vessel tricolor lights at or near the masthead and the normal running lights arrangement lower on the vessel.
