Electronic Navigation Mindset

Electronic navigation is an aid to navigation, not a separate standard of seamanship. A Yachtmaster-level navigator uses GNSS, chart plotters, radar, AIS, depth, log, compass, and visual evidence together. The important question is not 'what does the screen say?' but 'does the screen agree with independent evidence?'

The safest electronic navigation habit is cross-checking. Compare GNSS with visual bearings, radar ranges, depth contours, transits, and the compass. If two independent sources disagree, slow down, increase sea room if possible, and investigate before continuing into danger.
