The Sailing Expert application, a swiss knife for sailors, supports navigation, regatta, helps sailors to keep their logbook, shows weather forecast, keep maintenance log for different boats and more. The device's sensors are used to fill the log (location, COG, SOG, temperature, pressure). If a WiFi NMEA provider is available over WiFi the boat sensors will be used instead. Both TCP and UDP is supported. This app support Wear OS watch companion app showing the instruments on your watch. Please see https://sail.expert/permissions for how this app uses permissions. Supported NMEA Sentences: • GGA, GLL, GNS, RMC - Positioning • HDG, HDM, HDT, VHW - Heading • VBW, VHW, VTG - Course, speed • VLW - Trip log • DBT, DBP - Depth • RPM - Engine revolutions • MDA, MHU, MMB, MTA, MTW, MWD, MWV, VWR, VWT - Meteo/weather Navigation The application will tell you the target course or alert if you are off course, calculate the remaining distance and estimated time of arrival (ETA). • Routes: while sailing you can use routes to navigate • Target: fix a concrete bearing or target point of interest (POI) you want to sail to • Passage: the application help you plan a passage using a distance-time graph method • Startline: on regattas the application helps you to cross the startline on time and with optimal speed Charts • Map data from OpenSeaMap project or NOAA RNC are available in the application for offline use • Custom map servers can be used with this application (e.g. OpenStreet maps) • Local MBTiles files can be imported • Scanned maps can be imported, calibrated and setup up as a map source Weather forecast Global weather forecasts (NOMADS GFS, DWD ICON Global and selected locations) can be downloaded to the app and used during your trip. Trips • Trips can be prepared ahead with support of simple check-in and check-out for boat transfer • Trips or their parts can be exported to CSV, GPX and PDF directly from the app • Logged data can optionally be synchronized with https://sail.expert • Trip can be share between devices using P2P connection over WiFi Other • While on anchor the app monitors your location and alarms you if drifted outside the set area. Such area can be configured as a location and radius or a set of points (polygon). A second device can be setup to monitor anchor alarm remotely. • Simple expression can be set as alarms on different instruments • Optional contact suggestion feature when adding/editing people in the app (needs permission to read your contacts) User requested features and features based on feedback from our users • PDF export • Passage planner (distance-time graph) • Manual position fix • Audible speed coach • Maintenance log for boats • Anchor alarm • P2P data transfer between devices • In-app help (only EN) • Backup/restore Other features: • NMEA over WiFi • Weather forecast • Wind profile • Nautical map overlays • Navigation • OpenSea Maps • Man Over Board • Starting line • Units (metric, imperial, ...) • GPX, CSV export • Configurable instruments This application does not require an internet connection nor any registration for its basic function. We encourage our users to file reports if the application misbehaves or crashes. Reports can be filed in also by an email to [email protected]. Many thank for all reports and suggestions!
