Which bearing of a third object will give the best fix? #27 You 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? #28 You are inbound in a channel marked by a range. The range line is 309°T. You are steering 306°T and have the range in sight as shown in illustration D048NG below. Which action should you take? #29 You are entering port and have been instructed to anchor, as your berth is not yet available.

What action should you take? #30 Your vessel is entering port when you change course and steady up on a range with the lights in line. After a few minutes you observe the range lights as shown in illustration D047NG below. How should your heading be altered?
