🔍 Key Concepts

• Special vessels’ light configurations in the Navigation Rules (fishing, pilot, mine clearance) • Difference between being engaged in an occupation vs. just being capable of that occupation • When vessels are allowed or required to show identifying lights even if not actively working

💭 Think About

• For each vessel type in the choices, ask: Do the Rules allow it to display its special lights when it is NOT currently doing that specific work? • Think about why special lights exist: Are they to warn others of a current hazard/limitation, or simply to announce the type of ship at any time? • Consider which of these vessel types could create a false or misleading impression if it showed its special lights while not actually engaged in the activity.

✅ Before You Answer

• Check the exact wording in the Navigation Rules for vessels engaged in fishing (Rule 26), vessels engaged in pilotage (Rule 29), and mine clearance operations (Rule 27) • Verify whether any of these rules explicitly or implicitly allow identifying lights to be shown when not engaged in the relevant operation • Make sure you distinguish between mandatory special lights and optional identifying lights for each vessel type before choosing.
