SeaNav Mac Sailing

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 – or take your iPhone sailing, then send your track back to your Mac.

Plug in your GPS unit and go – 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. But GPS is only required for real time route navigation, you can plan routes without GPS then send them to your iPhone for use while at sea. SeaNav’s optional Real time AIS, Tides and Weather information require an active internet connection.

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