The wind at Frying Pan shoals has been north-northeasterly at an average velocity of 30 mph. The predicted set and drift of the rotary current are 355° at 0.8 knot. What current should you expect?

Correct Answer: Option B — 325° at 0.7 knot

Apply vector correction for wind-driven current as per standard maritime practice. Adjusting the predicted rotary current of 355 degrees at 0.8 knot for the north-northeasterly wind influence results in a net current of 325 degrees at 0.7 knot, reflecting the expected environmental deviation.
