Question 1 of 27070

BOTH INTERNATIONAL & INLAND At night, a power-driven vessel less than 12 meters in length may, instead of the normal navigation lights, show sidelights and one __________.

🔍 Key Concepts

• Rule 23 – Power-Driven Vessels Underway in the Navigation Rules • Special provisions for small power-driven vessels under 12 meters • Difference between flashing lights and normal navigation lights

💭 Think About

• What light (color and character) is normally used to indicate a power-driven vessel’s presence and direction at night? • For small power-driven vessels under 12 meters, what is the simplified lighting option allowed instead of the full masthead and stern light arrangement? • Do the Rules ever require a flashing light for a vessel that is simply underway and not engaged in special operations (like towing, air-cushion, etc.)?

✅ Before You Answer

• Check what Rule 23(d) says about vessels less than 12 meters and what lights they may combine or substitute. • Verify whether a flashing light is used for ordinary power-driven vessel navigation, or mainly for special signals (like maneuvering, air-cushion, or distress). • Confirm the color and steady/flashing character of the basic forward-facing light used by power-driven vessels underway.
