FerryDodger – Ferry Alerts NAV

FerryDodger 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.
