🔍 Key Concepts

• Rule 3(d) – Definition of a vessel engaged in fishing in the Navigation Rules • Difference between having fishing gear on board and actively using gear • What it means for fishing gear to restrict maneuverability compared to an ordinary power-driven vessel

💭 Think About

• Look for the choice that matches the formal definition in Rule 3(d), not just common-sense language about fishing • Ask yourself: Does the definition depend on the gear simply being present, being used in any way, or being used in a way that affects how the vessel can maneuver? • Consider whether the rules specify any particular distance or type of gear, or if they describe an effect on the vessel instead

✅ Before You Answer

• Verify the exact Rule 3(d wording in the Navigation Rules (COLREGS/INLAND) • Check whether the rule includes or excludes gear like trolling lines from the definition of "engaged in fishing" • Confirm whether the rule mentions any specific distance (e.g., 100 meters) or whether that is not part of the definition
