What it does

Best departure window

Tells you whether to leave at 1:00 or 3:00 — scans the tide cycle and finds the start time that catches fair current through the passes.

Routes around land

A* routing over a water grid bends your course around islands and shorelines — no straight lines through the beach.

Sails the wind

Motor-sail hybrid model with real tacking: upwind legs beat at your boat's tack angle; downwind and reaches sail.

Time-aware conditions

As you progress, the clock advances — so each leg uses the NWS forecast and NOAA tidal current for when you'll actually be there.

Your boat, your routes

Save boat profiles (cruise speed, sail speed, tack angle, fuel burn, draft) and reusable routes. Optional cloud sync across devices.

Export to your plotter

Send the planned route as GPX to Navionics, OpenCPN, Garmin and more — or share a link that opens the route for anyone.

Where it works

More regions on request — the data is generated per area.

Pricing

Planning is free. Plan routes, see conditions, find your best departure — no account needed.
Exporting routes to your chartplotter (GPX) is $4/month Pro. Cancel anytime.

Important

Planning aid only — not for navigation. Always use official charts and your own judgment. Wind, wave, and current values are model forecasts, not observations, and routing is approximate.
