🔍 Key Concepts

• Rule 14 – Head-on Situation of the Navigation Rules • What lights are shown by a power-driven vessel underway at night • How sidelights appear to another vessel when meeting nearly end-on

💭 Think About

• Think about what you would SEE from ahead when two power-driven vessels are meeting nearly on reciprocal or nearly reciprocal courses at night. • Ask yourself: if you can see this specific combination of navigation lights, does it mean the other vessel is almost directly ahead of you? • Compare what you would see in a true head-on approach versus an overtaking or crossing situation—how would the visible lights differ?

✅ Before You Answer

• Verify which answer choice correctly describes the combination of navigation lights you would expect in a head-on meeting between two power-driven vessels at night. • Make sure the condition you select relates to relative bearing and visible lights, not to sound signals or distance alone. • Confirm that the option you choose matches the definition in Rule 14 – Head-on Situation for power-driven vessels.
