A free passage planner for sailors. It times your departure to the tides & currents, routes around the land, factors wind & waves along the way, and exports straight to your chartplotter.
Free to use · no login required to plan · Pacific Northwest & US West Coast
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.
A* routing over a water grid bends your course around islands and shorelines — no straight lines through the beach.
Motor-sail hybrid model with real tacking: upwind legs beat at your boat's tack angle; downwind and reaches sail.
As you progress, the clock advances — so each leg uses the NWS forecast and NOAA tidal current for when you'll actually be there.
Save boat profiles (cruise speed, sail speed, tack angle, fuel burn, draft) and reusable routes. Optional cloud sync across devices.
Send the planned route as GPX to Navionics, OpenCPN, Garmin and more — or share a link that opens the route for anyone.
More regions on request — the data is generated per area.
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.
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.
