I've been watching the highlights, but with declining interest. I think that the root of the problem is that the boats are going too fast, so they basically avoid each other. There isn't enough time for the tactician to think and decide when a crossing is imminent: tack, duck or cross? The other problem is that you have to look very closely to see whether the boats are on an upwind or downwind leg. In the kind of racing that I do, spinnaker handling is often the deciding factor, because there are so many ways to mess up (for example, broaching to windward on SF Bay!). As in other areas of life, advanced technology has stripped the life and pleasure out of something wonderful.
