🔍 Key Concepts

• Definition of advance during a turning circle test (distance gained in the original direction from the point where rudder is put over until a specified change of heading is reached). • Identifying from the table the exact line where right full rudder is ordered and the headings that bracket a 75° change of heading from the original course. • Using ranges and bearings of a fixed light to plot successive vessel positions and then measuring distance along the original course line to the interpolated 75°-heading position.

💭 Think About

• From the initial heading of 228°, what new heading corresponds to a 75° change to starboard, and between which two recorded headings does that fall? • When you plot the two positions on either side of that heading, how can you interpolate to find the approximate position at exactly that heading before measuring advance? • Are you measuring from the correct starting point (when the rudder was ordered), and only the distance in the original course direction, not along the curved track?.

✅ Before You Answer

• Be sure you use the position at RIGHT FULL RUDDER ORDERED as the starting point for advance, not the earlier point "ON INITIAL COURSE". • Confirm that your 75°-change heading lies between two recorded headings and interpolate between their plotted positions before measuring. • Measure the final distance parallel to the original course line (not along the arc of the turn) and convert your measurement to yards to compare with the answer choices.
