SeaNav on the Apple Watch

Unlike other Marine Navigation apps on the AppStore, SeaNav comes with a really useful and free Apple Watch App which shows live navigation information, waypoints, compass, wind display and AIS radar. Waypoint reached and CPA (AIS collision) alerts also show up on your Apple Watch.

You can add a launch complication for SeaNav to your main Watchface, so you can tap and go straight to SeaNav.

You can also launch SeaNav by tapping its icon in the Apps view on the watch

Stop and start sailing a route by tapping the boat icon with the cross on it.

SeaNav is now Sailing the currently selected route with the boat symbol showing the heading. SeaNav on your iPhone will also now be in Sailing mode recording your track etc.

Next up is the wind display. This shows a compass with boat heading up, true and apparent wind direction plus the port (red) and starboard (green) laylines ( for sailing). The bearing to the next waypoint is also shown in light blue.
