| Didn’t mean size - should have been clearer, I was referring to aspect ratio. I think junk rigs tend to be short because they hoist too much hardware and lines (and weight) aloft.

Interesting. I had not considered that.
How much heavier is a junk rig?

But even so, as I understand wings, and to a lesser degree, sails, one is better with a higher aspect ratio than raw square footage, and, if one moves to a more square planiform, one drops the effective coefficient of lift, for the same foil.

I had assumed most junks had low aspect ratios because they were refits for existing masts. Or the mast choice was restricted

If one can build ones own mast, and wanted to fit a junk rig, could one not raise a higher aspect ratio, higher performing junk for almost the same weight as short square one? Probably have a lower or identical com and coe too?
