You only have to look at the 12 foot skiffs... There's two sorts of faster, faster through the water and faster round the course. With a smaller kite and hotter angles you are inevitably going to be faster through the water, but the evidence seems to be that geometry wins out and lower and still pretty quick wins races.

But look at foiling cats. There a flatter kite is faster around the course. 

In light winds you can't put much weight against the kite otherwise the apparent will go to far forward and create a load of drag on the deep cut kite. Then you'll just end up sailing the same speed but higher. That's why the 49er went to tighter cuts and slightly smaller too but faster round the course as well as straight line. There's a Canadian article describing the feel on this for 49ers somewhere... 

Then in heavy winds if the kite is too big you can't get the flow initiated over it which is slow also. 

But the 14 doesn't have great leverage s you can see why they went for a fuller kite to take the depth. 

I just wonder a what amount of righting moment and hull drag that it starts to become faster in VMG to have flatter or smaller kites.

20 knots... with probably 2 knots of current and fat water for a nano second!

Nice yacht around a week or so ago. Not much water in the harbour put a focus on boat handling but the flat water made it quite nice. A bit of sun helps too!
