NavLink Charting
NavLink utilises the latest S57 based digital mapping and features automatic updates for each year's subscription. With vector mapping, you can manage your layers of data to de-clutter the screen or maximise information. NavLink supports all key charting feature such as buoys, lights, bridges, depth contours, spot depths, depth contours, anchorage and military areas etc.

Interfacing
NavLink is compatible with all Digital Yacht's wireless NMEA devices such as the iAIS, WLN10, WLN10HS, NavLink, iNavHub and PilotLink that stream wireless AIS data to your Apple device

If you have a WiFi-only iPad you will need an external Bluetooth GPS receiver to enable navigation. 3rd Party units are available such as the Garmin Glo.

Please note: Continued use of GPS running in the background can dramatically decrease battery life
