🔍 Key Concepts

• Navigation Rules – Part C (Lights and Shapes), especially special vessel lights • Meaning of a single all-round white light over a single all-round red light shown together • Differences between lights for power-driven, pilot, fishing, and special operations (aircraft) vessels

💭 Think About

• Identify what a normal power-driven vessel underway would show from dead ahead or nearly ahead. Would it be only these two all‑round lights? • Recall the memory aids for special vessels (for example, short phrases used for pilot and fishing vessels) and match them to the white over red combination. • For a vessel at anchor and fishing, think about whether an anchor light and/or sidelights are required in addition to any red/white combinations.

✅ Before You Answer

• Verify in the Navigation Rules which vessel shows one all‑round white light over one all‑round red light when underway but not making way. • Check whether a vessel engaged in fishing at anchor may display only these two lights, or if it must show anchor lights as well. • Confirm what lights a pilot vessel on pilotage duty must show, and compare that exact pattern to the illustration.
