I was wondering what happened also. The page wasn't updated for some reason. Using the drop down box in the middle above the map, select the next most recent time and you should see them. For example, if the page defaults to 12:00, manualy select 10:00.
Hi, apparently earlier today there was a glitch at the 1200 hour (noontime), and it seemed as if no boats were being tracked. Everything is fine now, and congratulations to either Sjambok or Donnybrook, I'm not sure who finished ahead of the other!
