Question 1 of 2066636ee728f7522a1c5177c2

You are conducting trials to determine the maneuvering characteristics of your vessel. While making a turn, you take ranges and bearings of an isolated light with the results as shown. Based on this information, what is the advance for a turn of 45°? Illustration D034DG

🔍 Key Concepts

• Advance vs Transfer in a turning circle – know which is measured along the original course line • Using true range and bearing of a fixed light to plot the vessel’s geographic position at different headings • Interpolating between plotted points to estimate the position at exactly 45° change of heading (from 228° to 273°)

💭 Think About

• From the table, at what heading and remarks is the rudder first put over? That plotted position is your starting point for measuring advance. • Which two plotted points bracket the moment when the ship’s heading is 45° to starboard from 228°? How can you estimate the in‑between position on your plot? • Once you have the estimated 45° position, how do you project that point back to the original 228° course line to read the distance of advance?

✅ Before You Answer

• Be sure you are measuring only along the original 228° course line, not sideways from it – that sideways distance would be transfer, not advance. • Confirm that you are using the true bearings and ranges of the same isolated light for every plotted point. • After plotting, double‑check that the heading at your “advance” point is approximately 273° (228° + 45°) before you read off the distance in yards.
