SeaNav uses the latest Digital Vector charts providing a wealth of benefits and advantages over raster charts. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, 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.

SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and collision alerts.

SeaNav is also available for iOS, so you can plan a route on your Mac and share the route with your iPhone or iPad.

Real-time route navigation requires a GPS location.
Inexpensive 3rd Party units are available to add these accurate location capabilities to your device. SeaNav works with Bluetooth and serial GPS units, and those which provide location or AIS service via TCP or UDP or TCP, including devices from Lowrance, Simrad and B&G GoFree.

Your purchase of SeaNav includes 12 months free updates to the included UK chart set.
