You are steering 287°T, and a light is picked up dead ahead at a distance of 19.4 miles at 0419. You change course to pass the light 4 miles off abeam to starboard. If you are making 13 knots, what is your ETA at the position 4 miles off the light?

Correct Answer: Option B — 0547

Based on standard maritime piloting principles, determine the total distance required to reach the abeam position by applying right-triangle geometry using initial range and passing distance. Dividing by the speed of 13 knots gives the exact travel time, resulting in an ETA of 0547.
