🔍 Key Concepts

• Definition of "underway" vs "making way" in the Navigation Rules • How stand-on and give-way status is determined in a crossing situation (Rule 15) • Correct use of lights and shapes for vessel not under command and restricted in ability to maneuver

💭 Think About

• Think about whether a power-driven vessel that is stopped in the water but not disabled is still considered underway under the Rules. • Ask yourself what conditions must exist before a vessel may display not under command or restricted in ability to maneuver signals. • Consider, in a normal crossing situation, which vessel is typically the give-way vessel and whether simply being stopped changes that responsibility.

✅ Before You Answer

• Verify the exact definition of "underway" in the Navigation Rules (is a stopped vessel still underway?). • Check the specific criteria in the Rules for a vessel to be classed as not under command or restricted in ability to maneuver. • Confirm from Rule 15 – Crossing Situation how relative position (port vs starboard) affects give-way and stand-on status, regardless of speed.
