Planning a route around reefs and islands
The route check shows how much of a route other boats have measured, and every stretch where they found the water shallower (or deeper) than the seabed model.
Draw a route
- Tap the route button on the left of the map (the dotted line between two dots).
- Tap where you start, then tap where you're going. If your boat's position is live, the route starts at your boat and you only tap the destination.
- The panel shows the distance, the bearing (°T), the time at your planned speed, how much of the route boats have measured, and any stretches that differ from the model.
Go around reefs and islands: drag the line
- Press on the orange line and drag with your finger (or mouse). A numbered waypoint appears where you let go, and the route bends around it.
- Add as many waypoints as you like. Each leg is checked against community soundings.
- Move a waypoint: drag its blue numbered badge.
- Remove a waypoint: tap it and choose Remove waypoint.
- Reverse turns the whole route around, waypoints included.
While you sail
Turn on Follow my boat and the route starts at your boat as you go. The panel shows the distance and time to go at your current speed, your ETA, and how far you've sailed. The bearing points to the next waypoint, and each waypoint drops off when you're within 100 m of it.
What the colours mean
- Red circles on the route: boats measured less water than the seabed model there. Tap the stretch in the panel to fly to it.
- Blue circles: boats found deeper water than the model.
- No soundings yet: the route goes where no boat has logged. That doesn't make it safe or unsafe; nobody has measured it yet.
The route check is a planning aid. It only knows what boats have measured, and it can miss a coral head between tracks. Always use your charts, allow for the tide and your draft, and keep a lookout.
