This is a real-time marine traffic and vessel tracking app for anyone who needs an accurate, live picture of what is happening on the water — whether you are tracking a specific ship, monitoring a port, planning a passage or simply following maritime traffic out of professional habit or personal interest. Five operational sections. Everything you need to read the sea. SECTION 1 – VESSEL MAP The live foundation of the app — everything starts here. Open the Vessel Map to see real-time AIS positions of ships, tankers, cargo vessels, ferries and recreational boats plotted on an interactive chart. Zoom into any area, filter by vessel type and tap any icon to pull up the ship's current status, speed, heading and destination at a glance. Use this section when you want an immediate answer to where a specific vessel is right now — or when you simply want to see how busy a stretch of water currently is. SECTION 2 – REAL-TIME AIS TRACKING The engine behind every position on the map. AIS data updates continuously so every vessel position, course and speed reflects the actual current state — not a cached snapshot from minutes ago. Track individual vessels in real time, follow their route as it develops and monitor changes in speed or heading as they happen. Use this section when you are tracking a specific ship on a specific route and need the data to stay current throughout the journey. SECTION 3 – SHIP INFO Deep information on any vessel you select. Tap any ship on the map or search by name, IMO number or MMSI to open its full profile: vessel type, flag, dimensions, build year, current operator and voyage history. See where the ship has been, where it is heading and what its current port of call is. Use this section when you need more than a position — when you need to know what you are looking at and why it is where it is. SECTION 4 – WEATHER Conditions layered directly over the maritime picture. Check current and forecast weather for any point on the map — wind speed and direction, wave height, visibility and pressure — so you can read traffic patterns in context. A vessel holding position outside a port makes more sense when you can see the weather it is waiting out. Use this section when you are planning a passage, assessing risk in a specific area or trying to understand why traffic in a zone looks the way it does. SECTION 5 – PORT DETAILS AND TRAFFIC Full operational picture of any port in view. Select any port to see its current traffic — inbound, at anchor, at berth and recently departed — alongside port details including location, facilities and contact information. Monitor whether a port is congested, quiet or actively receiving traffic before a vessel arrives. Use this section when you are coordinating arrivals, monitoring port activity or planning logistics around specific terminals and facilities. All five sections share the same live data layer — so the ship you identify in Section 3, the weather you check in Section 4 and the port traffic you review in Section 5 all reflect the same real-time operational picture at the same moment.

About

FerryDodger

Read full description

FerryDodger is the sailing planner that goes to sea with you: plan the route, check the weather along it, see where you'd cross a ferry lane, then sail LIVE with alerts — offline too. PLAN THE ROUTE Draw the route on the map: waypoints snap to water and the coastal path is computed automatically, keeping the boat off land and — with your draft set — out of the shallows. Set departure and average speed and every leg gets its passing time. WEATHER ALONG THE ROUTE Four forecast models (GFS, ECMWF, ICON, GEM) compared for wind, gusts, waves, swell and rain. A 2-hourly table for any point at sea, color-coded Quiet / Rock / War against YOUR thresholds; the route line itself is colored by the forecast at the time you'll pass. Weather mode lays wind, waves and point of sail over the route. DEPARTURE ANALYSIS The best windows to leave in the coming days, with the expected points of sail (close-hauled, reach, run), wave direction relative to the boat — all computed offline. ROUTE SUMMARY One glance: ferry crossings and when the first one comes, duration and arrival time, wind and waves expected for that departure, the points of sail you'll actually sail. DEPTHS AND HAZARDS, WORLDWIDE Download your region's data from the Maps page or with one tap from the route: coastline and harbours in vector detail, depth contours and shallow-water bands, rocks, wrecks and obstructions, and coastal place names, all offline. Europe uses EMODnet 2024 (~115 m grid), the rest of the world GEBCO 2024 (~460 m). This is open data, not an official nautical chart. Packs include the ferry lines and stay valid for 12 months from download, then you download them again for free. Optional: the offline base map. FERRY LANE CROSSINGS Every point where your route crosses a ferry lane mapped in OpenStreetMap, on the map and in a list with distance from departure and estimated crossing time. The app flags the crossing with the lane: it does not know where the ships actually are. LIVE NAVIGATION Follow your GPS position on the route: speed, miles run and remaining, next crossing with ETA, weather ahead, arrival time and daylight left. Get a notification + vibration before a crossing at the distance you choose, even with the screen off. Free navigation mode without a route, too. With an AIS receiver on the boat's Wi-Fi: nearby vessels, course vectors and collision alarms (CPA/TCPA), with the screen kept on. ANCHOR ALARM At anchor, set the anchor where you are or on the map and choose the radius: if the boat leaves the circle or GPS is lost, sound and notification. On iPhone with the screen off only the notification arrives. OFFLINE Ferry data, maps and the forecasts you've viewed stay on the phone. PRIVACY No account, NO ADS. Your data stays on the device: your GPS track is never uploaded, and the weather and map services receive only the coordinates needed to answer: in LIVE, your position goes to the weather service. FREE FerryDodger is free and ad-free: no subscription, no in-app purchases. Paid features may arrive in the future, always announced in advance and never as automatic charges: what you use today stays free. SAFETY DISCLAIMER FerryDodger is a planning-support and alert tool. Bathymetry and hazards are indicative open data (~115 m grid in Europe, ~460 m elsewhere) and do not replace official nautical charts, a certified AIS display, radar or a proper lookout. Responsibility always remains with the skipper. The anchor alarm does not replace an anchor watch.
