A Small Boat Cruising Guide to Shark Bay
The sets of waypoints referenced in the book are available for download. Click HERE.
The waypoints are stored in .GPX (most GPS systems) or in USR (some Lowrance systems).
If conversion into other formats is required, GPSBabel is a good free download for Win XP, Win 7,8,10, OSX and Linux.
eg Some Lowrance Units require imported data to be in .USR format. GPS Babel will convert GPX to USR.
A useful PC program for viewing or editing the waypoints is EasyGPS which will load the waypoints onto a large variety of GPS units, including Lowrance, Garmin and Magellan.
