Deeper understanding.

Find your race, then take it apart. OSCAR rebuilds the fleet from tracker data and compares each boat with its polar, the current and an optimal route. The archive runs from Lake Geneva dinghies to transatlantic races.

For

Offshore racers, crews and coaches reviewing a completed race.

Do

Replay the fleet and compare performance, current, shifts and route choices.

Evidence

Tracker positions, boat polars, current fields and route calculations.

Opens

Learn from real races. Build better strategies. Retrace applies machine intelligence to fifteen years of historical data: thousands of races, tens of thousands of boat entries and hundreds of thousands of analysed legs. It goes deep into what repeatedly improves performance, what does not, and how you can race better.

For

Racers, navigators and coaches looking for repeatable strategic patterns.

Do

Study race types, boat families and the choices associated with better results.

Evidence

Fifteen years of race results, boat entries, tracks and analysed legs.

Opens

A forecast should be open to inspection. Passage identifies the depression, front and timing behind a passage forecast. Claims link back to source evidence, and completed forecasts are checked against the weather that followed.

For

Offshore sailors planning a passage or checking a forecast afterwards.

Do

Build a route briefing, inspect scenarios and audit what the forecast got right.

Evidence

Forecast models, ensembles, tides, currents and observed weather.

Opens

The Passage planner, where you enter route, timing and boat details.
