The wind at Frying Pan shoals has been west-northwesterly at an average velocity of 40 mph. The predicted set and drift of the rotary current are 323° at 0.6 knot. What current should you expect?

Question

The wind at Frying Pan shoals has been west-northwesterly at an average velocity of 40 mph. The predicted set and drift of the rotary current are 323&deg; at 0.6 knot. What current should you expect?

Accepted Answer

Option A: 018&deg; at 0.4 knot. Utilize the vector analysis method for wind-driven current corrections. By applying the west-northwesterly wind influence to the predicted rotary current of 323 degrees at 0.6 knot, the resultant vector shifts to 018 degrees at 0.4 knot, accounting for the localized meteorological impact on the tidal stream.
