🔍 Key Concepts

• Rule 24 – Towing and Pushing (Navigation Rules) • Rule 27 – Vessels Restricted in Their Ability to Maneuver (RAM) • Difference between basic towing lights and additional lights when another condition also applies

💭 Think About

• Ask yourself: when a vessel is both towing astern and also severely restricted in maneuverability, do the rules replace one light configuration with another, or do they add requirements? • Think about what lights a normal towing vessel underway would show first. Then, consider what extra lights might be required if it is also restricted in its ability to maneuver. • Which answer choice best reflects the idea that a vessel may need to show lights for more than one condition at the same time?

✅ Before You Answer

• Verify in Rule 24 what lights identify a vessel towing astern: masthead(s), sidelights, stern light, and towing light(s). • Check Rule 27 to see what additional lights are required for a vessel restricted in its ability to maneuver (RAM). • Confirm whether a vessel that is both towing and RAM keeps its towing lights, RAM lights, or a combination. Focus on whether the rules say ‘in addition to’ or ‘instead of’.
