You are underway and intend to make good a course of 040°T. You experience a current with a set and drift of 190°T at 1.4 knots, and a northwest wind produces a leeway of 3°. You adjust your course to compensate for the current and leeway, while maintaining an engine speed of 10 knots. What will be your speed made good over your intended course of 040°T?
Official USCG Answer & Rule Citation
Correct Answer: Option A — 8.8 knots
Compensating for 3° of leeway and a 1.4-knot current set at 190°T requires a specific heading adjustment. The resulting Speed Made Good along the 040°T track is calculated by resolving the velocity vectors, yielding 8.8 knots after accounting for the current's significant opposing component.
