You are enroute to assist vessel A. Vessel A is underway at 5 knots on course 063°T, and bears 136°T at 78 miles from you. What is the course to steer and running time at 13 knots to intercept vessel A?

Question

You are enroute to assist vessel A. Vessel A is underway at 5 knots on course 063&deg;T, and bears 136&deg;T at 78 miles from you. What is the course to steer and running time at 13 knots to intercept vessel A?

Accepted Answer

Option D: 115&deg;, 7h 20m. Current-sailing and interception vector triangles solved via Bowditch methods require determining the relative movement between own vessel and the target. Steer course 115°T at 13 knots to achieve interception in 7 hours and 20 minutes.
