Navvygator - GPS for the Inland Waterways

Navvygator is a GPS mapping application for use on the UK Inland Waterways.

It has been used for over three years by experienced boaters, and downloaded and installed by over 2,000 boaters, who have all tested the software in real world situations. Their feedback has enabled the software to fit the needs of leisure boaters and continuous cruisers.

The software uses the detailed waterway maps from Water Explorer to display the canal and rivers as you cruise, augmented with the street and town maps from the Open Street Map project.
