Real-time vessel tracking and custom geofenced watch zones anywhere on Earth. Engineered for boaters, waterfront residents, and maritime spotters—track ships, tugs, tankers, and yachts across any ocean, bay, river, or harbor worldwide with instant alerts.
Built from the waterline up with high-frequency live AIS ingestion, GPU-accelerated vector radar, deterministic geofencing, and zero-battery-drain alerts across any waterway on Earth.
High-performance vector mapping with smooth 60 FPS nautical charts. Track container ships, coastal tugs, tankers, ferries, and yachts with sub-second position updates, course vectors (COG), speed (SOG), draught, and vessel metadata on high-density marine charts.
Draw custom circular geofences anywhere on Earth—over your local marina, mooring, harbor channel, or coastal shipping lane. Server-side spatial engines evaluate vessel entries and exits in real time without polling.
Zero device battery drain. Cloud-evaluated event pipelines dispatch instant native notifications via Firebase Cloud Messaging. Filter by vessel type (cargo, tanker, tug, passenger, pleasure craft) with intelligent anti-chatter cooldowns.
Multi-source live AIS ingestion—including AISStream and Open Waters—engineered for continuous expansion with additional maritime data streams. Automated coverage verification classifies incoming signals across direct terrestrial VHF, verified regional telemetry, and global streaming feeds.
Your personal device location is never tracked, stored, or uploaded. Watch zones are fixed geographic coordinates defined by you and evaluated entirely on private servers to safeguard your privacy.
Born out of observation along the Hudson River's dynamic shipping lanes. Crafted with high-contrast marine abyss palettes for effortless night-vision observation from dark wheelhouses, docks, or waterfront decks.
Hudson Watch was born along the storied bluffs of the Hudson River—inspired by the high-density maritime traffic of commercial tugs, fuel barges, container feeder ships, and passenger ferries navigating the Hudson Valley. That relentless tidal waterway served as our demanding proving ground for high-frequency VHF reception and instantaneous geofence alerting.
Today, that same battle-tested telemetry engine delivers universal global reach: monitor any ocean, sea, coastal strait, river, or harbor worldwide where you drop a watch zone.
