At 0925, you plot the following bearings and range:
Falkner Island Light: 251°T at 1.7nm Kelsey Point BW Light: 075°T If you correct for a current setting: 215°T
what course will you steer from the 0925 position to arrive at a position 0.5 mile south of Long Sand Shoal West End Horn Buoy "W"?
• Course to steer vs. course over ground when current is acting • Plotting a fix from two bearings and a range on the chart • Using a current vector (set and drift) to adjust your intended track
• After plotting the 0925 position, where is the point 0.5 mile south of Long Sand Shoal West End Horn Buoy "W" relative to that fix? Is it generally to the east, west, north, or south? • If the current is setting 215°T, in what general direction will it push your vessel on the chart? How does that affect whether your steering course must be slightly more to the left or right of the desired track? • When you lay down the desired track line from your 0925 fix to the objective point, and then apply the current vector, what does that do to the heading you must steer to end up on that line?
• Be sure you have the correct 0925 fix by accurately plotting the two bearings and the range to Falkner Island Light and Kelsey Point BW Light. • Confirm that the point you are navigating to is 0.5 mile due south of Long Sand Shoal West End Horn Buoy "W" (not from your current position). • Double‑check that you have applied the current setting 215°T in the correct direction (toward 215°T) when constructing your current vector on the chart.
