You are steering 202°T, and a light is picked up dead ahead at a distance of 14.6 miles at 2234. You change course to pass the light 5 miles off abeam to starboard. If you are making 21 knots, what is your ETA at the position 5 miles off the light?

Correct Answer: Option D — 2313

In accordance with Bowditch navigation techniques, resolve the right triangle where the hypotenuse represents the run from the initial detection point to the abeam position. Dividing this calculated distance by 21 knots yields the exact time interval, confirming an ETA of 2313.
