I would like to have a possibility to tracking my yacht.

If you have your own boat, you've probably noticed that it is equipped with its own GPS receiver, which enables the navigation and prevent collisions when it is at the time of the trip. It is a device that is placed on most yachts.

 

But actually rarely encounters a device that records the route and allows you to browse it later. We used for this purpose smartphone running Google Android. Just install the software CarTrack and put the device in the cockpit. The application saves the route and allow the creation of, for example, the album containing the routes.

 

Here you can find a short report about  tracking water units.
