57. From your 1210 position, you are making good a course of 083°T. Your engines are turning RPMs for 10 knots. The set and drift of the current are 310° at 1.7 knots. At what time should you expect to enter the red sector of New London Harbor Light?

The correct answer is 1243. The running time to the red sector boundary, calculated from the distance along your track and accounting for the current's effect on your speed over ground, is approximately 33 minutes. Adding this to your starting time of 1210 results in an ETA of 1243.
