In nautical terms, what does "set and drift" refer to?

• A. The wind's direction and speed
• B. The vessel's rotation and pitch
• C. The current's tendency to push the vessel in a given direction during a turn
• D. The ship's ballast movement

Answer: (C)

Set and drift describe how a current affects a vessel’s path. Set is the direction toward which the water is moving, and drift is the speed at which the vessel is carried by that current. Together, they tell you where the vessel will tend to go, especially as you maneuver or turn. If you’re turning and the current has a particular set, it will push the hull in that direction, altering your track unless you compensate by adjusting heading. Wind, the vessel’s own rotation or pitch, and ballast movement involve different factors and aren’t what set and drift describe.
