Under the Rules, a vessel transferring cargo while underway is defined as what type of vessel?

• A. A vessel restricted in her ability to maneuver
• B. A vessel not under command
• C. A vessel engaged in a towing operation
• D. A vessel constrained by her draught

Answer: (A)

During operations that limit how a vessel can move, such as transferring cargo underway, the vessel is considered restricted in her ability to maneuver. This classification signals other vessels to take extra care and give more room, because the active work can prevent quick changes in course or speed and the vessel may not be able to avoid a collision as readily as a free-moving vessel.

This isn’t about being completely unable to move (that would be not under command), nor about being limited by water depth (that would be constrained by her draught), and it isn’t describing a towing operation. Transferring cargo while underway fits the idea of restricted maneuvering because the ongoing task inherently constrains how the vessel can maneuver.
