Wind Router.

Browser weather routing for sailboats. It combines a boat's ORC polar with live forecast weather to suggest the fastest route between two points — respecting the best wind angles and steering clear of land and shallows — all drawn on a nautical chart. Built first for S/Y Astarte.

• ORC polar speeds
• Live Open-Meteo wind
• Isochrone routing
• Nautical vector chart

Your boat, your numbersChoose the boat and it loads her ORC certificate — every speed on the route comes from your real polar, not a guess. Pick the forecastECMWF, ICON-EU, GFS, or “Best” to auto-pick. “met.no” shows when your model has no data for these waters. Two models, two tracksEach weather model gets its own route. Where the lines split, the forecasts disagree — plan for that spread. Forecast windWind across the whole area for the hour you’re viewing — arrows give direction and strength at a glance. Conditions at the boatFollows the boat as you scrub the timeline: true and apparent wind, boat speed, elapsed hours, local time. Sail it throughStep or play along the passage to see where you’ll be at any hour before you slip lines. Night legs & ETAThe band shades darkness — see which stretches you’ll sail in the dark — plus departure and arrival times. Best sailing anglesYour boat’s ORC polar. Marked angles are the highest you’ll point upwind and the deepest you’ll carry downwind in this breeze.
