You are underway on course 204°T at a speed of 17.3 knots. You sight a light bearing 205°T at a radar range of 4.7 miles at 1222. If you change course at 1228, what is the course to steer to leave the light abeam to port at 1.5 miles?

Correct Answer: Option D — 236°T

Calculate distance traveled between 1222 and 1228 (6 minutes at 17.3 knots = 1.73 miles). Plot the initial position and the target abeam position. Using the relative motion triangle, the course change required to pass the light at 1.5 miles to port is 236T.
