PCDB Waypoints is not yet available commercially. It is a Microsoft Access database that stores details of voyages, routes, waypoints, seamarks, your crew, charts, NMs and many other aspects involved in owning and running a private boat.
Work has just begun on porting major aspects of this database to an Android platform, and progress on this adaptation is being recorded in our blog. The Android standard relational database tool SQLite will be used as the basis for this app.
