11.13 Set and Drift
Set, the direction of ocean current, can be manually entered in the nearest degree. Drift, the
speed of the ocean current, can also be entered manually, in 0.1-knot increments. Set and drift
corrections are beneficial for increasing the accuracy of vector data. The correction is best made
on relative motion with true vector, watching landmasses, buoys, or stationary targets. Thus, the
speed and course over the ground are reciprocally calculated and compared with the relative
bearing and range to the reference target produce set and drift.
