SeaNav Nautical Charts
SeaNav uses the latest Digital Vector charts providing a wealth of benefits and advantages over traditional raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.
Plan and Sail Routes
Use SeaNav to plan and sail routes. In-app tools let you measure distances and bearings and record waypoints on routes to sail. When you are out at sea, the app’s Sailing HUD shows your position on the route, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. An audible alarm sounds as you reach a waypoint and routing automatically moves onto the next waypoint. You can also share and import routes from others and MFDs like Raymarine and Simrad etc.
Exploring Your Surroundings
As you use SeaNav it will automatically download and store the charts for the area you are viewing. The level of detail on the charts changes as you zoom in and out. Tapping an object – buoys, lights, bridges, ships etc. – shows detailed information about them. A long press reveals a crosshair and a popup with depths, links to information about tides, moon and sun times and weather for the area plus links to any objects that are near the crosshair. Tapping again leaves the crosshair showing so you can drag the map to get a particular point under the crosshair and tap again to get information about it.
Augmented Reality view (iOS)
Our unique AR view mode allows you to view buoys, lights, ships, waypoints and track overlaid on your iPhone or iPad live camera view. With “AR LockOn” you can select a target on the chart and then be guided to it in the AR camera view.

User Guide
For detailed information on how to use SeaNav, please consult our iOS User Guide or Android User Guide – the User Guide is also included in the app, so you can refer to it while you are using the app on your device. There is also a demo simulation mode in the app so you can try out all the sailing features back at home. See the demo user guide for more information. Our extensive FAQ can also offer you help and advice on getting the best out of SeaNav.
Requirements
GPS is required for real time route navigation. Weather and live AIS Ship positions require an active internet connection. Tides and streams are stored for offline use for up to 5 days ahead. Tide information for months or years ahead is available.
Please note that continued use of GPS running in the background can dramatically decrease battery life.
