You are underway and intend to make good a course of 088°T. You experience a current with a set and drift of 300°T at 2.4 knots, and a southerly wind produces a leeway of 3°. You adjust your course to compensate for the current and leeway, while maintaining an engine speed of 16 knots. What will be your speed made good over your intended course of 088°T?

Question

Accepted Answer

Option D: 13.9 knots. After adjusting the heading for 3° of leeway and the 2.4-knot current set at 300°T, the Speed Made Good is determined by the vector sum along the 088°T track. The resulting speed over ground is 13.9 knots, calculated using standard maritime navigation vector resolution.
