Ok, thanks y'all. I think what I originally suspected is true.
My basic question was really looking at how, given the proper angle of the main as defined by any standard "points of sail" diagram, can cats do this since they aren't able to wing out as far.
The answer seems, as best we can. I've observed that letting the main out keeping the traveler mid or even slightly to wind
gives me a wider angle towards the middle of the main's curl.
If they could just get rid of the stays and keep the same basic rig. Does make me wonder about things like the twin mast
configurations I've seen, not the least of which the new Chris White.
