FerryDodger – Ferry Alerts NAV

Ferry Dodger watches the ferry lanes so you don't have to. Draw your route, and it shows you exactly where you'd cross a ferry line — then alerts you before you get there.

⛴️ AVOID THE CROSSINGS
Plan a route and FerryDodger finds every point where it intersects a ferry lane (OpenStreetMap data). See each crossing on the map and in a list, with distance from your start and an estimated time of crossing. Know what's ahead before you cast off.

🧭 LIVE MODE — ALERTS UNDERWAY
Follow your GPS position along the route in real time: speed, miles run and remaining, % of route done, and the next crossing with its ETA.
• Get a NOTIFICATION + VIBRATION as you approach a crossing, at a distance you choose (default 2 miles) — even with the screen off or the phone in your pocket.
• OFF-ROUTE AWARE: drift from your drawn line and FerryDodger recalculates distance, ETA and alerts from your real position.
• WEATHER STRIP in Live: wind, gusts, direction, expected point of sail, wave height, plus arrival ETA and remaining daylight (sunrise/sunset offline) for departure, midway and arrival.
FerryDodger is an ALERT tool, not a turn-by-turn navigator.

🌤️ WEATHER & DEPARTURE WINDOWS
Compare 4 forecast models (GFS, ECMWF, ICON, GEM) along your route — wind, gusts, waves, swell and rain — to find the favorable windows and the best times to leave. Includes expected points of sail and sunrise, sunset and moon phase, all computed offline.

📡 WORKS OFFLINE
Before you leave, download the corridor map plus ferry data. Your position and alerts keep working far offshore with no signal — and weather stays cached too.

🗂️ ORGANIZED BY TABS
The route detail screen is split into clear sections — Overview, Ferries, Departures, Weather — with simple tab navigation.

🔒 PRIVACY
No account. NO ADS. Your data stays on your device, and your GPS position is never sent to any server.

🌍 LANGUAGES
English, Italian, Spanish and French.

⭐ FERRYDODGER PREMIUM
Live Mode is free for a few minutes per session, restartable after a short wait. FerryDodger Premium (annual subscription, in-app purchase) makes Live Mode unlimited with no waiting. Everything else — planning, crossing map, weather and offline — is free.

⚠️ SAFETY DISCLAIMER
FerryDodger is a planning-support and alert tool. It does not replace official nautical charts, AIS, radar or your duty to keep a proper lookout. Responsibility always remains with the skipper.
