Todd - Initially I like the idea of clipping in to the sheets as well. Except that in the case like what happened to me the main would already be tight and the traveler almost or centered already - in other words I'm not certain the boat would flip quickly, and I'm not sure what the experience of being dragged would be like. At least if a bungeed tether were involved the shock of being yanked by the boat might be lessened. Would the shock load on the main system cause a failure there?
Also, for that case, Alec was on the wire and the boat finally turned downwind and de-powered. When it capsized it capsized on top of him to windward. The only thing he had a grip on was the bungee from the trap line. In other words, he was close to being separated as well. If both sailors get separated... If he at least had been clipped to the spin sheet he would have been in good shape.
The entanglement issue is big, too.
If this happens in a bouy race I really don't care that much. When it did happen was during distance races, and the prospect of having it happen in the Tybee (as has already happened) is a little fearsome.
So, anybody been personally dragged by a tether or sheet? Anybody capsize while tethered?
