🔍 Key Concepts

• Look closely at the colors and vertical/horizontal arrangement of the lights in the illustration (green over white, plus a separate green). • Review Navigation Rules Annex I & Rule 26 (Fishing Vessels) and Rule 29 (Pilot Vessels) and the special mine‑clearing and sailing vessel lights. • Remember the common memory aids for special lights, such as phrases that match color sequences to vessel types.

💭 Think About

• Which vessel type is associated with a green and white light combination at night, and how are those lights arranged (vertically vs horizontally)? • For each answer choice, ask yourself: what is the standard color pattern for that special vessel (e.g., pilot, minesweeper, sailing, trawling), and does it match this picture? • Does any of the listed vessel types show three green lights or white over red, and how does that compare to what you see here?

✅ Before You Answer

• Verify in the Navigation Rules which vessel shows green over white all‑round lights when underway at night. • Check which vessel type displays white over red all‑round lights (and eliminate that choice). • Confirm which vessel type uses three green all‑round lights in a specific pattern, and see if the illustration matches or not.
