Thanks for saying it so well, Bob. I was going to point that out in my question and exclude those as candidates, but then what would be left to say?

All the higher-tech cats and bigger cats seem to have internal halyards. So of that internal-halyard group of cats, which has the best halyard lock?

And if none of them has a "best" halyard lock, why doesn't somebody invent something that works better -- that WILL work with an internal halyard?

Somebody mentioned the Supercat having its halyard lock at the bottom of the mast, inside the sail track. Is that correct?
