Sailwx

Sailwx is an integrated maritime information service that aggregates worldwide ship locations into a single map. Weather conditions including ocean currents, wave height and tides are also available and can be integrated into ship location maps.

Locations of ships in territorial waters and on the high seas are provided on a zoomable world map making the service the maritime equivalent to 'Google Maps' for shipping. Not all ships worldwide are mapped. Ship track maps are based on data reported via the World Meteorological Organization's Voluntary Observing Ship (VOS) service or the YOTREPS network of cruising yachts.

This information service acts as a free aggregator of maritime Automatic Identification System (AIS) information to provide real-time cartographical ship-location context for worldwide news events involving maritime shipping such as acts of piracy, oil spills, whaling-ship confrontations, and so forth.
