You are underway on course 150 degrees true at 8 knots. Your vessel is making good a course of 166 degrees true and a speed made good of 8.8 knots. What is your set and drift?

* Step 1. Plot out course of 150 degrees true on Radar Plotting Sheet
* Step 2. Measure length of course by using speed of 8 knots and converting into nautical miles via the time, speed, and distance scale
* Step 3. Plot the length of speed on Radar Plotting sheet
* Step 4. Plot out desired course of 166 degrees true on Radar Plotting Sheet
* Step 5. Measure length of course by using speed of 8.8 knots and converting into nautical miles via the time, speed, and distance scale
* Step 6. Connect the two ends of the vectors from the current course to the course made good. Thus creating your set and drift vector
* Step 7. Using the navigational triangle, place on set and drift vector. Then drag to center crosshairs keeping the same angle and find the degrees on the outer circle
* Step 8. Measure the length of the set and drift vector with the compass.  Convert from nautical miles into knots using the time, speed, and distance scale.
* Step 9. Your set is 230 degrees true at a drift of 2.5 knots
