Which description correctly identifies a power-driven vessel?

• A. A vessel propelled by sails only
• B. A vessel not making way
• C. A vessel engaged in fishing
• D. A vessel with propelling machinery in use

Answer: (D)

A power-driven vessel is one that is propelled by machinery. The defining point is that the propelling machinery is in use, actively driving the vessel through the water. That’s why a vessel with propelling machinery in use is the correct description: the engines or other motors are engaged, producing forward motion. A vessel propelled by sails only is not power-driven, since it relies on wind. A vessel not making way might be stationary or drifting even if it has engines, so it isn’t inherently defined as power-driven. A vessel engaged in fishing could be powered or sail-driven, but the phrase “in use” specifies that the propulsion machinery is actively being used, which is what makes it a power-driven vessel.
