Unleash the Power of Data for Offshore Routing
Dorado, cloud-based offshore routing software, leverages a vast dataset to deliver advanced and detailed routing recommendations. Designed for professional sailors and used by cruisers globally, Dorado combines advanced algorithms, cloud processing power, and cutting-edge route analysis to optimize performance and safety on every voyage. Sail smarter, sail faster, and stay ahead of the competition and the weather.
Data at your fingertips

Dorado is designed to revolutionize offshore sailing by harnessing the power of the cloud. By integrating diverse datasets, including ECMWF and GFS weather forecasts alongside wave and current forecast data, it delivers routing analysis with unparalleled precision.
Unlike traditional methods, where sailors manually download weather data and run a single routing on their devices, Dorado shifts the heavy processing to the cloud. This approach enables the simultaneous analysis of multiple datasets, offering richer insights that go far beyond the conventional solutions.
With Dorado, every routing request unlocks advanced capabilities. Access to high performance computers enables fast generation of multiple scenarios based on ECMWF and GFS ensemble forecasts. These scenarios reveal the spectrum of possible weather conditions, accounting for variations in initial conditions and slightly perturbed weather models.
Dorado is in a public beta. Works best in Chrome on a desktop computer.
Built in partnership with ARSO, Slovenian Environment Agency.

KEY FEATURES
Dorado is packed with cutting-edge capabilities designed to transform offshore routing. Explore the tools that set Dorado apart.
Deterministic Routing
Harness ECMWF and GFS forecasts to generate reliable routing solutions. Visualize wind patterns, wind barbs, and isochrones to chart your optimal course.
Ensemble Routings
Analyse all ensemble members – 51 from ECMWF and 21 from GFS to reveal a full spectrum of potential scenarios, and gain valuable statistical insights.
Polar Spread
Evaluate scenarios across a range of polar efficiencies, from 80% to 120%, helping you understand how varying performance levels impact your optimal route.
Advanced Routing
Enhance your planning with detailed routing tables, meteograms along your route to know what conditions to expect, and seamless CSV export for further analysis.
Customized Performance
Tailor your routing with wave correction tables and sail configuration tables. Adjust wind speed corrections based on your first-hand experience.
ECMWF & GFS Models
Models support 0.25° grid and 1-hour resolution, and include detailed data on wind, gusts, pressure, total cloud coverage, 2-meter temperature, and precipitation.
Wind Comparison
Visually compare wind data differences between ECMWF and GFS models with intuitive visualization tools to gain deeper insights into forecast variations.
Wave and Ocean Models
Analyze ECMWF WAM and GFS WaveWatch III wave models for swell and wind wave conditions, and Mercator Ocean NEMO model for currents and sea surface temperature.
Meteograms
View meteograms along your route or at any selected point to analyze wind speed, pressure, cloud cover, precipitation, swell, wave height, waves, and currents for a comprehensive understanding of conditions.
Custom Polyline Routes
Create your own polyline routes and have complete control over your planned course. Perform detailed routing analyses along these custom paths to tailor strategies to your specific journey.
Inclusion and Excl. Zones
Define precise inclusion and exclusion zones to shape your routing strategy. Dorado ensures your routes respect these boundaries, helping you avoid hazards or navigate within preferred areas effortlessly.
Testimonials
Dorado began as a specialized tool for Vendée Globe sailors and has since become a trusted resource for hundreds of professional sailors and cruisers worldwide. First introduced during the 2020 race, it was used daily by leading competitors, including the winner, Yannick Bestaven, who graciously recorded a thank-you video for us. In the 2024 edition, Dorado has gained even greater traction, becoming an essential tool for many participants. We look forward to sharing more testimonials as our journey continues.
