Q

BOTH INTERNATIONAL & INLAND Which lights is a vessel not under command, underway but not making way, required to exhibit?

🔍 Key Concepts

• Rule 27 – Vessels Not Under Command (Navigation Rules) • Difference between “underway” and “making way through the water” (Rule 3) • Difference between status lights (showing a vessel’s condition) and navigation/running lights (showing motion and heading)

💭 Think About

• First decide: what special lights identify a vessel as not under command regardless of whether it is moving or not? • Then ask: when a vessel is underway but NOT making way, do the normal sidelights and sternlight have to be shown, or are those only required when the vessel is actually moving through the water? • Think about why sidelights and sternlight exist: what information are they supposed to give other vessels about your motion and aspect?

✅ Before You Answer

• Look up the exact wording of Rule 27(b) for a vessel not under command and note which lights are ALWAYS required. • Check the part of Rule 27 that mentions “when making way through the water” and see what extra lights are added ONLY in that case. • Verify whether sidelights and sternlight are tied to the vessel’s condition (NUC) or to its movement through the water (making way).
