Maritime tools

Tools built on data Seadar collects and keeps: the lanes ships actually sail, learned from AIS position history; ship positions where our sources allow us to show them; and NOAA buoy readings and tide predictions. Every tool is free to use without an account.

Sea distance and route

Port-to-port distance in nautical miles and kilometres, and sailing time at your speed, along learned shipping lanes.

Port conditions

Tide times, wind, waves and water temperature from the NOAA stations nearest a port.

Ship ETA estimate

When a ship could reach a port: remaining distance along the lanes from its latest position, at its recent speed.

Chokepoint monitor

Ships crossing Suez, Panama, the Bosphorus and other canals and straits: transits today, the queue at anchor, the trend.

Need answers for many ports or ships at once? Pro runs each tool for a whole CSV or watchlist in the Terminal, with CSV download. See Pro
