You are enroute to assist vessel A. Vessel A is underway at 6 knots on course 133°T, and bears 042° at 105 miles from you. What is the course to steer at 10 knots to intercept vessel A?

Question

You are enroute to assist vessel A. Vessel A is underway at 6 knots on course 133&deg;T, and bears 042&deg; at 105 miles from you. What is the course to steer at 10 knots to intercept vessel A?

Accepted Answer

Option D: 079&deg;. Current-sailing and interception problems are solved using a relative motion vector triangle. Constructing the triangle with target vessel speed, bearing, and own ship speed of 10 knots dictates an intercept course of 079°T per Bowditch navigation methods.
