Scannav is a mapping software with all the functionalities that can be expected from a navigation software (definition and storage of roads, definition of danger zones, automatic map change...). It is compatible with maptech charts (bsb format available under the marine chart link), softchart charts and the new official S57 format. Its user-friendly interface will allow you to get started easily and efficiently.
As an option, it is possible to add an AIS module, a tidal current module and a weather module.
