Which designs thrive in heavy air?
Weather Intelligence is live. ERA5 meteorological reanalysis — wind, wave, and pressure — across the race-dates in coverage.
For the first time, FleetEdge reveals the relationship between design type and racing conditions. Combined with the 11-archetype MPAE engine, weather enrichment shows how each archetype performs in specific conditions — light air, heavy breeze, offshore swell.
You can now see whether a boat's race results reflect skill, conditions, or both. ERA5 reanalysis is sampled against race-leg centroids and venue bounding boxes timed to each running's actual window, providing a consistent meteorological record from the moment each race in coverage started to the moment it finished.
This changes what race results mean. A boat's win in light air tells a different story than the same win in heavy air. Design characteristics that favor specific conditions become visible. Crew performance can be isolated from environmental factors. The archetype-condition interaction emerges as a measurable dimension.
Weather Intelligence turns race results into calibrated, condition-aware performance data — quantifying the conditions that shaped each race against the fleet that raced it.
Six condition and tactical dimensions.
Weather enrichment adds six measurable dimensions to race records carrying ERA5 coverage.
Dominant Wind Band
The prevailing wind speed category for the race.
Race Wind Median
Median wind speed across the race duration.
Weather Coverage
Percentage of race duration with meteorological observations.
Condition Residual
Performance delta attributable to weather conditions.
Weather Observation Count
Number of ERA5 data points matched to the race.
Archetype Condition Fit
How well the design type suits the conditions.
ECMWF ERA5 Reanalysis.
ERA5 is the fifth generation ECMWF atmospheric reanalysis, produced at 31 km horizontal resolution. Unlike live weather forecasts, reanalysis data is retrospectively computed using the full global observation network — producing the most complete and consistent meteorological record available.
FleetEdge matches ERA5 grid cells to race-leg centroids and venue bounding boxes timed to each running's window, extracting wind speed, wind direction, significant wave height, mean wave period, and surface pressure. Reanalysis — not forecast — is the right instrument here: only the retrospective global observation network gives the historical accuracy a race-condition record requires.
The result is a weather archive that grows as new races are added to FleetEdge — a foundation for understanding design performance across the spectrum of conditions the corpus covers.
Where current matters, current is read.
Atmosphere is one axis. On the five IRC offshore classics — Cowes, Fastnet, Rolex Middle Sea, Sydney–Hobart, and RORC Caribbean 600 — the water is the other. Tidal gates split fleets by hours, not minutes, and a weather-only record under-describes the race.
HYCOM Ocean FleetEdge reads HYCOM GLBy 93.0 ocean-current reanalysis at 1/12° horizontal resolution, sampled against the same race-leg centroids and venue bounding boxes the atmospheric layer uses and timed to each running's actual window. The two layers sit side by side in the record rather than in competition.
Current intelligence is flagship-scoped at launch across those five races; atmospheric coverage is corpus-wide. See Ocean Intelligence for the race-by-race current treatment.
