The easiest way to prepare OSM offline maps and make them available without internet connection is as follows:
1. Open the application before going into sea, while you have internet connection
2. Select Open Street Maps cartography (Menu -> Cartography)
3. Preview on the map the locations where you plan to sail, in different zoom levels
By this procedure, all the maps loaded for display, has been stored in the phone memory and will be retrieved in case there is no connection.

1.The official method would be through the download option on the OSM website
2. Convert the downloaded OSM files into “tiles”, with application like OsmAndMapCreator
Once converted into tiles, copy the tiles into the following mobile path:
