🔍 Key Concepts

• Rule 3(d) – Definition of “vessel engaged in fishing” (Navigation Rules) • Difference between fishing with nets/lines/trawls that restrict maneuverability vs. trolling (which usually does NOT restrict maneuverability) • Rule 26 – Fishing vessel lights and shapes, and how they differ from ordinary power-driven vessels

💭 Think About

• Ask yourself: According to the Rules, when is a vessel officially considered “engaged in fishing” – is it any time someone has a line in the water, or only when gear restricts the vessel’s ability to maneuver? • Compare what lights a fishing vessel shows under Rule 26 with the light combinations listed in the choices. Do any of the options clearly match a different type of vessel (for example, a vessel not under command or at anchor)? • Think about fog signals: Does a vessel engaged in fishing have a unique fog signal, or does it follow the same signal as any other power-driven vessel underway (making way or not)?

✅ Before You Answer

• Verify in Rule 3(d) that “engaged in fishing” EXCLUDES trolling. • Check in Rule 26 which light colors and order (red over white / white over red) are assigned to fishing and trawling vessels, and which combinations belong to other vessel types. • Confirm in Rule 35 whether a vessel engaged in fishing uses the same or different fog signal as a power-driven vessel underway and making no way.
