When comparing twin screw tug to single-screw tugs, which statement about a twin- screw tug is FALSE?
Official USCG Answer & Rule Citation
Correct Answer: Option C — It develops more bollard pull for the same horsepower.
Bollard pull is primarily a function of total installed horsepower and propeller efficiency. A twin-screw configuration offers superior maneuverability and redundancy, but it does not inherently increase total bollard pull compared to a single-screw vessel of identical horsepower; in fact, it may be slightly less efficient due to hull interaction.
