navigation, unbound.

Instant, silk-smooth charts on any tablet. Weather routing from the same forecast data commercial apps charge for — free. An open sensor bridge for ~$100. No subscriptions, no marine-tax markup.

the living chart

designed for the helm.

Most plotters show a digital photocopy of a paper chart and call it done. Vane renders charts the way a game engine draws a world — smooth depth gradients, crisp detail at every zoom level, and nothing waiting to redraw while you're entering a narrow channel. 60fps on a $200 tablet.

readable at a glance

High-contrast depth gradients you can read in direct sunlight or on a night watch.

shows what matters

At anchor: marinas and services. Underway: hazards and nav aids. Less clutter, fewer mistakes.

the brain

weather routing. free.

ECMWF forecasts at 0.25° resolution. CMEMS wave and current data. The same models that commercial routing apps charge $30/month for — processed on our servers, delivered to your tablet, no subscription.

Set your departure, your destination, and your weather window. Vane computes the optimal route using real wind, wave, and current forecasts — not just a straight line with a wind arrow on top. Overlays update every 6 hours.

included free — no subscription

vane horizon

see what the weather can't decide.

64 ensemble forecasts from Google DeepMind's WeatherNext 2, run simultaneously on every passage. Where they agree, you have a good window. Where they diverge, you see the risk — before you leave the dock.

Confidence corridors show you the spread. Auto-learned polars from your Vane Bridge mean routing is calibrated to your boat in your conditions — not a generic datasheet. No spreadsheets. No guesswork.

philosophy

vane is not a plotter.
vane is a smarter helm.

Government charts are free. EU open data directives made ECMWF weather forecasts free. The sensors are commodity parts. The only thing keeping marine electronics expensive is the software — and the companies that charge you $30/month for data your taxes already paid for. We're building the alternative.

No subscriptions. No "marine tax." No expiration dates. The app is free. The weather routing is free. The hardware is open. That's how this should work.

be first on the water.
