Expedition is a Windows navigation software package for professional offshore sailing and yacht racing. The site states that it has been used in multiple editions of the Volvo Ocean Race, America's Cup, and Grand Prix events, and that it has been continuously developed since the mid-1990s by veteran offshore racing navigator Nick White. The current version is v12.7.16, with support for Windows 11 or 10; Windows 11 is recommended.
In terms of features and use cases, Expedition covers chart plotting, weather analysis, route optimization, race starts and buoy-racing management, instrument networking, AIS/radar display, data logging, and post-race analysis. For charts, it supports S-57, S-63, BSB RNC, Navionics, C-MAP X, and C-MAP 4D. For weather, it supports Grib 1/2 and NetCDF, and integrates a wide range of models and sources including WRF, ECMWF, GFS, ICON, HRES, AIFS, ENS, Saildocs, Squid, SailFlow, NOAA, Copernicus, and Tidetech. Its routing features include multiple optimal-route algorithms, fleet routing, ensemble forecast routing, wave correction, reverse isochrones, and polar analysis.
Its strength lies in compatibility with onboard equipment. The site lists support for B&G, Garmin, Iridium GO, NMEA 0183, NMEA 2000, AIS, radar, laser rangefinders, compasses, MOB systems, and various sensor systems. For racing teams, this ability to integrate instruments, weather, charts, and race data is more valuable than a standalone charting application.
The website only provides a Purchase licence option and does not disclose pricing, licensing model, payment methods, trial policy, or post-sales SLA. It also does not mention any API, SDK, plugin system, self-hosting option, or open-source information. From a developer-tool perspective, it is therefore closer to professional closed-source desktop software than to an open platform-style tool.
Its advantages are deep functionality, strong endorsement from professional racing, and broad support for formats and equipment. It is especially suitable for offshore racing, professional sailing teams, and navigators who need advanced weather routing. The downsides are that it is only explicitly supported on Windows, pricing and documentation are not very transparent, and the feature density creates a relatively steep learning curve. Casual recreational sailors may find it too heavy, and could consider alternatives such as OpenCPN, TimeZero, Adrena, or PredictWind Offshore.
The site does not provide information about network accessibility, payment methods, or China-specific service availability, so china_access can only be marked as unknown. If using it in China, users should additionally verify connectivity to the official website, licence purchasing, weather data sources, chart services, and external model servers.
