You are outbound in a channel marked by a range astern. The range line is 133°T. You are steering 315°T and have the range in sight as shown in illustration D048NG below. What action should you take?

Correct Answer: Option D — Come left to close the range then when on the range steer 313°T.

Applying Bowditch piloting rules, an outbound vessel observing an open range astern must steer toward the visual closure of the beacons, then resume the designated channel course of 313°T once established directly upon the range line.
