70% to passYou are outbound in a channel marked by a range astern. The range line is 309°T. You are steering 127°T and have the range in sight as shown in illustration D047NG below. What action should you take?
A
Come right to 129°T.
B
Come right to close the range then when on the range steer 129°T.
C
Come left until the range comes in line then alter course to 125°T.
D
Come left until the range comes in line then alter course to 129°T.
AI Explanation
The correct answer is B) Come right to close the range then when on the range steer 129°T. This is the correct answer because when navigating a channel marked by a range astern, you want to steer to keep the range line centered. By coming right to close the range, you will bring the range back into alignment. Once the range is aligned, you can then alter course to the desired 129°T heading. The other options are incorrect because: A) Coming right to 129°T directly would take you off the range line. C) and D) suggest coming left, which would take you further off the range line.
