I recorded some videos during my training with the A-cat. I took a short piece of the video that shows a tack and saved is a Windows media player format.

The reason that I mess with the centerboards during the tack is not to make the tack faster but to increase upwind speed. The tack is a bit slower when you mess with the centerboards.

Select the video tack.wmv and save it on your harddrive. Use the file on the harddrive when looking at the video, don't play it from the server.
