You are enroute to assist vessel A. Vessel A is underway at 5.5 knots on course 033°T, and bears 284°T at 43 miles from you. What is the course to steer and running time at 16 knots to intercept vessel A?

Correct Answer: Option D — 303°, 2h 32m

Applying vector triangle mechanics for search and rescue interception, plotting own ship speed of 16 knots against target data generates an intercept course of 303°T and an exact running time of 2 hours and 32 minutes.
