🔍 Key Concepts

• Rule 3(g) – Restricted in her ability to maneuver (RAM) definition in the Navigation Rules • How a vessel not under command (NUC) is defined differently from RAM in Rule 3(f) • Examples listed in Rule 3(g): dredging, surveying, underwater operations, laying/cable work, mineclearance, launching/recovering aircraft, etc.

💭 Think About

• Which of these options describes a vessel whose work or nature of operations prevents her from keeping out of the way of other vessels as required? • Which option describes a vessel whose condition, rather than her work, prevents her from maneuvering? • Look at the exact wording of Rule 3(f) and 3(g): which one is specifically listed as a separate category from Restricted in Ability to Maneuver?

✅ Before You Answer

• Review the exact definition of "vessel restricted in her ability to maneuver" in Rule 3(g) and note the examples given there. • Compare that to the definition of vessel not under command in Rule 3(f) and ask: is NUC included inside RAM or treated as its own category? • Check which of the answer choices is explicitly named in the RAM examples in Rule 3(g) and which is not.
