🔍 Key Concepts

• Definition of transfer during a turning circle maneuver (distance measured perpendicular to original course after a given change of heading). • How to plot ship positions from an isolated light using given true bearings and ranges. • Finding the position on the turning circle when the ship’s heading has changed 180° from the initial heading (reciprocal course).

💭 Think About

• From the data table, which heading represents a course that is 180° from the initial 228°? Is it listed exactly, or do you need to interpolate between two headings? • Once you plot the initial positions along the original course and the position at (or closest to) the 180° heading, what line represents the original track, and where do you drop a perpendicular from the 180° position? • After drawing that perpendicular, what is the scale distance in yards between the original track and the 180° position, and which option is closest?

✅ Before You Answer

• Be sure you are measuring perpendicular distance to the original course line, not along the curve or along the bearing to the light. • Confirm you are using the correct plotted point for the 180° heading (or an interpolated point between 022° and 053° headings). • Double-check the chart scale conversion from inches or millimeters on your plot to yards before matching to the answer choices.
