🔍 Key Concepts

• Navigation Rules International only – focus on Rule 24 (Towing and Pushing), Rule 26 (Fishing Vessels), and Rule 27 (Vessels Not Under Command or Restricted in Ability to Manoeuvre) • The difference between all‑round lights (seen 360°) and masthead/sidelights used by power‑driven vessels and tugs • How a vessel at anchor adds white anchor lights to its normal special lights (e.g., for NUC or fishing)

💭 Think About

• First, identify how many red and how many white lights you see, and whether they are arranged vertically in a line or separated; which rules use two all‑round reds or two all‑round whites? • Ask yourself: which of the four options would normally show towing lights and masthead lights versus all‑round special lights, and which would show fishing lights (red over white or green over white)? • Consider whether a fixed obstruction (like a pipeline) would be marked by this exact pattern, or if it would more likely be marked by a series of lights along its length rather than a compact “cluster” like the illustration shows.

✅ Before You Answer

• Count and note the arrangement: Are any of the lights clearly a vertical pair of all‑round lights of the same color? That points to a very specific status in the Rules. • Decide whether the white lights look like anchor lights (all‑round, vertical pair) or towing/masthead lights (on a power‑driven tug). • Check Rule 26 carefully: a vessel engaged in fishing at anchor must show both fishing lights and anchor light(s); ask whether the illustration actually matches that combination, or instead looks like a different special condition.
