Tidal correction & tidal triangle — understand set and drift
Tidal set vectorially in the course chain: tidal triangle, tidal correction and link to rwK and helm course — local on device.
Tidal set is underestimated
Set and drift change coastal distance faster than a compass error. Without network you need a clear tidal triangle — not a cloud spreadsheet app.
