The wind at Frying Pan shoals has been south-southwesterly at an average velocity of 30 mph. The predicted set and drift of the rotary current are 232° at 0.8 knot. What current should you expect?

Correct Answer: Option D — 224° at 0.4 knot

Rotary tidal current corrections for wind effect at Frying Pan Shoals require vector addition of the wind-driven current vector (derived from local wind speed and direction tables) to the predicted astronomical rotary current vector.
