The Clipper Round the World Yacht Race is currently on its final leg (Jamaica to Liverpool). Boats are currently racing for New York before headed to Nova Scotia, Cork, and finally to the finish at Liverpool (see the entire route). I wasn’t aware until recently that they had a Google Earth network link allowing you to follow the boat positions. The file also shows the entire race route. Each boat’s placemark contains position, speed, course, and a link back to the team’s web page. You can also view the official race viewer which uses a Google Maps mashup. The folks at Skylab actually won an award for developing the Race Viewer.
