Key features.
Auto-routing
Set departure and arrival and it plots a route avoiding shallows, restricted areas, and hazards — factoring your draft and beam. In tidal waters it picks the departure time that carries a fair tide.
Weather integration
Wind, waves, and visibility overlaid on the route. See where you'll hit headwinds and when sea state builds; bad sections are colour-coded so they stand out.
Tidal streams & heights
Transformative for the UK, Brittany, and the Solent. Stream arrows on the chart plus current-adjusted ETAs and fuel — the difference between a 4-hour passage and an 8-hour slog.
Multi-stop trips
Plan a week's itinerary with multiple stops; it optimises each leg's departure. Ideal for Greek-island or Croatian-coast hopping.
