Make every race day count.
Time on the water is limited and expensive. Offwatch Labs turns the relevant global and high-resolution local models, plus ocean-current guidance, into one clear forecast for your venue and racing window, so your team can prepare around a shared weather picture instead of piecing one together from generic weather apps.
Race days are too valuable to improvise the weather.
A regatta already represents travel, entry fees, crew time, preparation and a rare block of time together on the water. Starting without a dedicated forecast, or spending race morning reconciling several weather apps, uses valuable time on a problem that can be solved before leaving the dock.
A forecast cannot guarantee the result. It can reduce avoidable weather uncertainty before the start.
Limited race time
You do not get a race day back. Arriving without a coherent weather picture creates avoidable uncertainty before the first start.
Fragmented guidance
Generic weather apps show model outputs. They leave you to decide which guidance deserves weight, where it disagrees and how local effects may change the racecourse.
No shared picture
If the navigator, tactician, coach and crew begin with different assumptions, the team starts reacting instead of executing a prepared plan.
One race-ready forecast
Your team receives the likely evolution, uncertainty, credible alternatives and the clues to watch on the water in one crew-ready briefing.
More data is not the same as a race forecast.
Raw model output still leaves your team to decide which run matters, reconcile conflicting guidance and account for local effects across the course. Offwatch Labs does that work before race day and turns it into one clear view of the likely sequence, uncertainty and alternatives.
Read the synoptic driver
Pressure pattern, air mass and large-scale evolution establish what can develop across the race day.
Resolve the local picture
High-resolution guidance reveals thermal effects, terrain influence, channels, convergence and race-area gradients.
Compare, do not cherry-pick
Model spread, timing and known biases are weighed together. Confidence is stated, not hidden.
Apply navigator judgement
Numbers become a usable sequence, visual indicators, geographic effects and alternative scenarios for the race team.
One briefing the whole team can use.
Built around your venue, course areas and racing window. Detailed enough for the navigator to plan from, clear enough to brief the tactician, coach and crew.
Synoptic situation
The pressure pattern, air mass, warnings and evolution that set the limits for the local forecast.
Hourly wind sequence
Expected direction, strength, gusts and trends through the racing window, with ranges where uncertainty matters.
Race-area differences
Separate analysis for multiple course areas, additional comparison zones or key points of interest.
Model comparison
Meteograms and high-resolution wind fields reveal consensus, disagreement, timing changes and confidence.
Visual and geographic clues
Cloud, shoreline, terrain and thermal indicators your team can identify and use while racing.
Scenarios and outlook
The most likely development, credible alternatives and what to watch for, plus a next-day outlook where relevant.
Built around your racecourse.
Best suited to inshore racing, from windward-leeward courses to coastal races, and from dinghies to superyachts. We configure the forecast around the decisions your team is likely to face, not around a generic location.
Share the event details
Regatta, venue, dates, local racing window, likely course areas and specific team questions.
Map the race environment
We define the synoptic domain, race areas, comparison points and best available model suite.
Build the forecast
Guidance is compared, local effects are assessed, and the likely sequence and alternatives are interpreted and written by racing navigators.
Brief the whole team
You receive a clear PDF designed to support the navigator, tactician, coach and crew.
Interpreted and written by racing navigators.
Every forecast is written by navigators experienced in producing daily forecasts for training and racing, and in competing globally across boats from dinghies to superyachts.
Marcel Korte
Marcel leads the forecasting: meteorological analysis, model comparison and the interpretation of local weather effects. His racing experience includes being part of the Rolex Giraglia-winning team and sailing with Black Jack when the team set the Palermo-Montecarlo course record in 2024.
Joshua Weber
Joshua has 15+ years in sailing and 6+ years as a navigator. He was navigation lead for wins at Copa del Rey, the Rolex Giraglia and the Rolex Middle Sea Race. He turns complex guidance into racecourse priorities, visual cues and scenarios teams can use under pressure.
