1503. 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?

The rear range mark appearing to the right of the front mark indicates your vessel is to the right of the range line; therefore, alter course to the left and maintain a slight leftward heading to keep the range lights fine on the starboard bow.
