What's New

Release notes

Every improvement we ship to OpenSail, in plain language. The newest changes are at the top.

The pricing page catches up with the app

One correction in your favour.

  • Fixed
    Every forecast model at every tier. The pricing page listed 'all forecast models' and the model-disagreement layer as Passage features. The app has never actually held them back — every model and the disagreement view are included from Voyager at $59/yr, and the page now says so.

How we stack up, in writing

A new comparison section covers OpenSail against PredictWind, savvy navvy, Windy and LuckGrib, with every price sourced and dated.

  • New
    Comparison pages. One page per competitor plus a five-way overview, linked from the footer. Every competitor price links to the vendor's own page with the date we read it, and every page includes a section on where that competitor beats us. If your use case fits their product better, the page says so and links you out.

Playback follows your voyage's forecast

With a route on the map, the timeline and instruments now read the exact forecast your route was planned on — end to end.

  • New
    Voyage-pinned playback. Right after a new forecast starts publishing, the map's live timeline can briefly be shorter than the one your route was planned against — the scrubber used to stop partway while the route line kept going. Now, while your voyage is on the map, playback automatically rides the voyage's own forecast: the whole route scrubs, and the wind and wave readouts show the weather your route was actually optimized on.
  • New
    See which forecast you're on — and switch. The status pill at the top of the map now says when playback is pinned to your voyage's forecast, names the exact model run, and gives you a one-tap unpin to jump back to the freshest live weather.
  • Improved
    Honest fallbacks. If your voyage's forecast has been superseded and removed, playback falls back to the live timeline and says so plainly — the map never silently substitutes a different forecast while claiming it's the one your route used.

Corner controls stay readable

Two small map-corner fixes.

  • Fixed
    Map credits and loading status on top. Opening the map credits panel, or a 'Loading weather' moment, no longer hides behind the corner buttons — whatever you invoked is always the thing on top.

Map polish and playback honesty

The map's corner controls got a redesign, and the timeline now tells you when playback is temporarily shorter than your voyage.

  • Improved
    The helm dock. Anchor Check and Feedback now live in a tidy glass column that reveals its labels as you hover — nothing overlaps, on any screen size, and the map credits panel is finally readable.
  • Fixed
    Honest playback limits. Right after a new forecast run starts publishing, the map's playable timeline can briefly end before your voyage does. The bar now says so — and tells you scrubbing extends automatically after the next forecast update — instead of letting the boat silently stop mid-route.

Passage plans to island harbors

The navigation-only line beyond your forecast now reaches island-sheltered destinations and ocean-scale distances.

  • Improved
    Island landfalls. Destinations tucked behind islands — Horta in the Azores, and harbors like it — now get their dashed passage-plan line beyond the forecast horizon. The final approach is planned at a much finer scale than the open-ocean crossing, so island channels thread correctly.
  • Improved
    Any distance. The beyond-forecast passage plan now handles ocean-scale remainders (a thousand miles and more) in seconds, including routes that must round major landmasses like the Florida peninsula.

Transatlantic-scale passages

Ocean crossings of any length now plan cleanly — a routing bug that could reject very long passages from certain harbors is fixed.

  • Fixed
    Very long passages from enclosed harbors. Departing a bay or enclosed harbor for a passage thousands of miles out (say, Chesapeake Bay to the Azores) could fail with a routing error. The harbor exit and the ocean crossing are now planned at their own scales, and these voyages return a proper partial-forecast plan in seconds.
  • Improved
    No passage dead-ends. If route optimization ever hits its computation limit before the forecast runs out, you now get the weather-routed section plus a navigation plan for the rest — clearly labeled as a computation limit, never dressed up as the forecast's edge — instead of an error.

Voyages beyond the forecast horizon

Long ocean passages no longer stop at the edge of the forecast — OpenSail now routes what the forecast covers and plans the rest honestly.

  • New
    Partial-forecast voyages. A passage longer than the forecast used to be rejected outright. Now you get a weather-optimized route to the forecast horizon plus a navigation-only continuation to your destination — clearly marked on the map with a horizon marker and a dashed line, never dressed up as weather routing.
  • New
    Coverage, disclosed everywhere. The timeline, voyage HUD, comparison table, route history, public track pages, and GPX/KML exports all say exactly how much of your voyage is forecast-backed and how much lies beyond — including how far and roughly how long the remaining leg is.
  • Improved
    Smarter forecast-run selection. When the freshest model run hasn't published its long-range hours yet, OpenSail now uses the most recent run that actually covers your whole passage instead of failing — the exact cause of rejected multi-day routes for some Pacific passages.
  • Improved
    GRIB downloads cover the whole voyage. The route-corridor GRIB now spans your full track — including the leg beyond the forecast horizon — so the weather you download covers the ocean you'll actually cross.
  • Improved
    Route watches for the full passage. Forecast-change alerts on a long passage now stay active until you could realistically arrive, not just until the forecast ran out — and alert emails name the full voyage, not just the forecast-backed distance.
  • Fixed
    Honest errors and labels. Departures beyond the forecast get a clear explanation with real numbers instead of a generic failure. Dateline-crossing exports now produce valid GPX/KML on every chartplotter, and the comparison table labels duration as duration.

The new timebar

Weather playback and route scrubbing merged into one forecast ribbon, plus catamaran routing fixes.

  • New
    One timeline for everything. The weather timeline and route scrubber are now a single forecast ribbon — day cells, sunrise/sunset shading, wind strength coloring, and your route's time band in one place, on desktop and phones.
  • Improved
    Map footer rail. Layer toggles, legend, and playback controls consolidated into a cleaner footer rail that stays out of the chart's way on small screens.
  • Fixed
    Catamaran routing accuracy. Multihull polars are respected end-to-end — heel-based comfort penalties no longer apply to boats that don't heel, and replayed voyages match what the router actually sailed.
