Passage planning

Set & drift → course to steer

Given the track you want to make good, your boat speed through the water, and the current's set and drift, solve the heading to steer and the resulting speed over ground.

Intended track

Track to make good (°T)

Boat speed through water (kn)

Current

Set — direction current flows toward (°T)

Drift — current speed (kn)

Result

Heading to steer (true)—

Current correction angle—

Speed over ground—

Heading is true — convert to compass with the compass conversion tool.
