🔍 Key Concepts

• Review Rule 26 – Fishing Vessels and what color lights they carry when fishing and when hauling nets. • Review Rule 29 – Pilot Vessels and the meaning of a vertical white over red all‑round light combination. • Check Rule 30 – Anchored and Aground Vessels to see what extra all‑round white lights are required when a vessel is at anchor or aground.

💭 Think About

• Look carefully at how many lights are shown, their colors, and their vertical arrangement. Which option’s rule description matches that exact pattern? • Ask yourself: does a vessel that is aground or at anchor show only the special‑purpose lights, or must it also show anchor lights in addition to them? • For fishing vessels, compare the required lights for fishing versus fishing and hauling nets. Do either of those descriptions match a simple white over red pattern without any side or stern lights shown?

✅ Before You Answer

• Confirm whether a white over red vertical pair is associated with fishing vessels or pilot vessels in the Navigation Rules tables. • Verify if a vessel aground must display additional red lights or anchor lights beyond a simple white/red combination. • Check if a vessel at anchor is required to show more than one all‑round white light, depending on length, and see if that matches the illustration with just these lights.
