Ok...wait a minute, the A Cats are 70lbs. (160) lighter than the F16's (230) and they have a taller mast, so of course they are going to go upwind better.

I pass them all going downwind however!

As far as putting the A Rig onto the F16, that would be very interesting to see. What is their total mainsail area vs. ours?

And adding the jib to the F16, sailed solo, is a lot of fun in light/medium air. That's how I sail it at home, not at a regatta of course. But not sure how it would be with more sail area up high, as with the A cat main. In light air it would be great, but how about in a good blow?

Oh, and are you going to run your spinny off that A cat mast? I think if you keep the mainsheet tight, it might survive...or not!
