There is a new GPS Sports website http://www.sportstracklive.com to share tracks, compete, join groups, replay your sail etc.. It works live in realtime from your mobile or upload tracks after your sail from any GPS unit. It's completely free to use. Here are some Laser boat tracks made recently: http://www.sportstracklive.com/live/sports/search?what=laser&search=Search The site does full performance analysis, charting, play back and of course live tracking. If you would like any extra features pls feedback here. Thanks.
