Software Utilities Document and manage stores and equipment on board. Add the beauty of the waterfront to any computer and prevent screen burn in with nautical screen savers. Manage waypoints and routes and transfer them from GPS to GPS. Marine software utilities help you protect and manage resources while simplifying a complex yacht's systems. GPS Waypoint/Route Managers Most yachts carry more than one GPS.  Most sailors like to load the same route into all of those GPS units.  Many sailors also use computers that are ideally suited to managing numbers in easy-to-read tables.  GPS Waypoint/Route Management software uses computer power to back up and share waypoint information between GPS units.  Commercial packages support sophisticated ocean routing, too.     Reference Packages Carrying reference books onboard can be a drag--they're heavy and  take up too much space!  Many of the more popular volumes in the sailor's library are available on CD-ROM with convenient browser and look-up functions.
