🔍 Key Concepts

• Rule 3 – General Definitions in the Navigation Rules • Difference between a vessel constrained by her draft and a vessel restricted in her ability to maneuver • Examples of vessels whose work or operations limit their ability to maneuver

💭 Think About

• Ask yourself: which option matches the formal definition of a vessel restricted in her ability to maneuver in Rule 3? • Which choices describe specific situations (like shallow water or hazards), and which describe a vessel whose own work or operations limit her ability to maneuver? • Consider real examples: dredging, cable laying, buoy tending, mine clearance—what common feature do they share in terms of maneuverability?

✅ Before You Answer

• Look up the exact wording of “vessel restricted in her ability to maneuver” in Rule 3 of the Navigation Rules before choosing. • Carefully distinguish between “constrained by her draft” and “restricted in her ability to maneuver”—they are different defined terms. • Verify which choice refers to a vessel’s operations or work rather than environmental or situational conditions.
