I received this video clip last night via an e-mail list to which I belong. I must admit, having sailed aboard yachts now and then during my younger days, I watched it with my mouth hanging open in amazement. I "raced" according to the standards of 1970's ocean yachts - not the pro's, but weekend sailors out for some fun. The high technology of these modern boats, and the speeds at which they move . . . it's breathtaking! I can't imagine how the helmsmen keep them under control. In fact, I wonder whether computer-assisted steering (possibly by adjusting the angles of the hydroplanes and "keels") is being employed? I wouldn't be surprised.
Anyway, take a look and see for yourself how quickly things can go wrong. Turn your volume DOWN - the soundtrack is far too loud and violent.
I'm afraid that's no longer a "sport" in the old-fashioned sense of the term. It's professional, calculated to a nicety, and seems to offer little or no room for enthusiastic amateurs such as I used to be. That's a pity.
