Deck General USCG Q#2072 (Set 65)

Which tackle arrangement has the LEAST mechanical advantage?

Official USCG Answer & Rule Citation

Correct Answer: Option D — Single whip

A single whip consists of a single fixed block with no mechanical advantage, providing only a change in the direction of pull. Compared to a gun tackle (2:1), luff tackle (3:1), or twofold purchase (4:1), the single whip offers the least mechanical advantage for lifting loads.
