903. You are steering 143°T, and a light is picked up dead ahead at a distance of 18.2 miles at 2006. You change course to pass the light 5.5 miles off abeam to port. If you are making 14.5 knots, what is your ETA at a position 5.5 miles off the light?

The distance from the initial sighting to 5.5 miles abeam is calculated using the Pythagorean theorem, resulting in a run of approximately 17.34 nautical miles. This distance, at a speed of 14.5 knots, takes about 1 hour and 12 minutes. Adding this time to the initial time of 2006 yields an ETA of 2118.
