Wouter:
In your side by side sloop v unirig in F-16 post (top of pg.4) is not the jib added area to the unirig main, i.e., the 2 boats have the same mainsail?

Is not the jib a high lift high drag leading edge device and subject to this article: http://aerodyn.org/HighLift/multi.html

I'm just trying to understand, and I thought this article applied in principal. I remember Randy Smyth pulling to shore and removing his jib in a Worrell when it was blowing hard and it helped. He won that leg, but of course there was a lot more going on.

And it seems to me Hakan is talking about a unirig w/ genaker setup vs sloop w/ genaker.

Also it seems to me that most of the vessels you cite cannot reasonably be used to establish anything relative to beach cats or even this M32. Hydroptere is a large hydroplaning cat, at least some if not many of the others are monohulls
