You are steering 019°T, and a light is picked up dead ahead at a distance of 11.6 miles at 0216. You change course to pass the light 3 miles off abeam to port. If you are making 14 knots, what is your ETA at the position 3 miles off the light?
Official USCG Answer & Rule Citation
Correct Answer: Option B — 0304
The distance to the abeam point is the square root of (11.6 squared minus 3 squared), which is 11.2 miles. At 14 knots, the time required is 11.2/14 multiplied by 60, equaling 48 minutes. Adding 48 minutes to the initial time of 0216 results in an ETA of 0304.
