493. You are enroute to assist vessel A. Vessel A is underway at 6 knots on course 133°T, and bears 343°T at 92 miles from you. What is the course to steer at 9 knots to intercept vessel A?

To intercept a vessel, resolve each vessel's motion into east-west and north-south components and determine a course that results in both ships occupying the same position at the same time; this yields an intercept course of approximately 003 true.
