Using the iPhone's and iPad's and iPod touch's WiFi connection, iNavX™ can use instrument and position data for realtime charting and plotting. iNavX™ supports waypoints & routes including KML (Google Earth) and GPX. iNavX was supported by the vyacht wireless router from day one.
Digital and vectorized maps give an illusion of perfect results in your navigation. But I don't remember a summer without seeing boats being towed of underwater rocks in the Stockholm archipelago.

All we could do is queue up at the shipyard waiting for our turn on repair.
