On Wednesday, the Singlehanded Sailing Society started a single and double-handed sailing race dubbed the “LongPac” – its a race of 400 miles from San Francisco Bay to anywhere on Longitude 126° 40″W and return. The race is over by August 4th. But, you can track the race in Google Earth (including the positions of all the boats) thanks to the efforts of Magnatrax.net (which has provided live sailboat race tracking for other races – like the Caribbean 1500).
As of this morning, some of the boats are just now reaching the half-way point. It wasn’t until during the last decade that technologies (GPS, Internet, and communications) made it practical to track positions of sailboats on a long-distance race in real time. The link for the tracking interface also includes weather data overlays. You can also view the official race map (also provided by Magnatrax.net).
