🔍 Key Concepts

• Vessel not under command (NUC) vs vessel restricted in her ability to maneuver (RAM) – know which one is described as "unable to maneuver due to some exceptional circumstance" • The difference between lights (night) and shapes (day) in the Navigation Rules – they often mirror each other • What extra navigation lights a vessel shows when it is still making way, in addition to its special status lights

💭 Think About

• First, identify which type of vessel is being described by the definition in the question. Look up that exact phrase in the Navigation Rules definitions (Rule 3). • Once you know the vessel type, recall the standard pattern for its special lights (two all-round red lights in a vertical line) and then match that to the correct day shape pattern. • For the choices that mention making way at night, think: what are the normal running lights for a power-driven vessel underway? Which answer pairs those with the special two red lights mentioned in the question?

✅ Before You Answer

• Verify in the rules which vessel type shows two all-round red lights in a vertical line and/or two balls by day. • Check the day-shape pattern: is it two balls, or ball–diamond–ball, or three balls? Confirm the exact order and meaning. • For the "making way at night" options, confirm whether a vessel with this status still shows normal sidelights, stern light, and possibly masthead light(s) in addition to its special lights.
