🔍 Key Concepts

• Rule 3 – General Definitions in the Navigation Rules, especially the definition of a vessel restricted in her ability to maneuver (RAM) • The difference between a vessel not under command (NUC), a vessel engaged in fishing, and a vessel restricted in her ability to maneuver • Specific examples listed in Rule 3(g) of work that makes a vessel "restricted in her ability to maneuver"

💭 Think About

• Look up the exact wording of the definition of a vessel restricted in her ability to maneuver and see which types of work are listed as examples. • Ask yourself: which of these choices describes a vessel whose work itself prevents her from keeping out of the way of other vessels, even though her engines and steering may be working properly? • Compare which categories already have their own separate definitions in Rule 3 (for example, fishing and not under command) and which one is explicitly given as an example of a RAM vessel.

✅ Before You Answer

• Verify in Rule 3(g) that a RAM vessel is one which, from the nature of her work, is restricted in her ability to maneuver as required by the Rules. • Check which of the options are explicit examples listed in the RAM definition, rather than just being a different defined vessel type (like NUC or fishing). • Confirm that a vessel at anchor is defined separately and consider whether being at anchor by itself meets the "nature of her work" restriction described in Rule 3(g).
