Lots of comments on limits to sail area. Just to examine specifics, the Mystere 4.3 website compares STOCK boat specs.

Now Mr. Bob, would you share the specs for your new H14 Maxi square top main and "Blaster" furling headsail, please? This is a combo that seems to work (from my point of view 300 yards behind you). We might gain some insight from your successful experimentation.

Say, wouldn't your first set of rules for sail area (160 sq ft) have ruled out your own boat? (see attachment)
