Not taking sides, I will add here that I've seen tethers required by cat clubs before, and these were experienced cat sailors (really old New England 100 days). IIRC, they were required on the boat, but you didn't have to be clipped in.
Tethers, like PFDs, are tough. People have been trapped under boats and unable to escape without removing their PFD. Others have been saved only because of the PFD. Other than probabilities, one group isn't more "right" than the other.
Bring dragged behind a boat is no fun, neither is having the boat drift away from you with no rescue boat in sight. Would make the EPIRB and VHF on your person suddenly much more important, though...

Mike,
Saying you've seen the tether requirement before and it was supported by very experienced sailors (in your opinion btw) doesn't really make as strong a point as you think it does. Just because someone else does or says something won't change my position unless they have a very compelling argument. I have an EPIRB on my person (my crew does too) I'm NOT tieing myself to the boat. If that's a rule then so be it, I have other options.
And for f!@k sake take a position! The middle of the road is completely uninteresting. Even though Mark annoys the piss out of me he almost never bores me. When he channels Wouter is when he bores me.
