I think the key in answering my questions is this comment from gbrungra, thanks gbrungra!

Found a polar for the 2013 America's Cup:
From: http://www.cupinfo.com/cupstats/index-a ... ots-02.php
I'm sure the AC boats have gotten faster with four years of development, but VMGs of 20kts upwind and 37kts downwind (absolute best case, rounding up, from the charts) aren't significantly better than current kitefoilers.
Maybe today's kitefoilers could beat the 2013 AC boats, but the 2017 AC boats have surpassed kitefoilers?
I didnt know that they have published these statistics.
Would be nice if we could have them from our top kitefoil races.
Although I am certainly not an expert of this matter but based on the comments important seems to be:
1. Velocity Made Good (VMG) at True-Wind-Angle (TWA) with a given wind speed
2. Type of race course.
3. Wind speed limit's for the craft
If I examine the america's polar I'm quite surprised that it doesn't look as impressive as I thought it would, compared to ones I have seen from the kitefoilers. Or I'm wrong?
What kind of race course? As I don't think matchracing is a good comparison for two different sailing crafts I will choose the Olympic triangle course. So no reaching at the begin and end (which is in favor of the AC45)
As I stated in my first post, I said 7 knots of wind on a race course.
7 knots because both crafts should be ok to foil, with some margin.
Probably has a kiter a lower wind limit then the AC45, but at 7 knots both should be ok.
In conclusion I would say that on an Olympic race course with 7 knots of wind the AC45 probably would win (if they are not the French team, they don't have kiwi's on board do they?). But not with that big margin sailors would hope for.
Otherwise matchracing or speed course, big win for the AC45's
Solely on money invested a big win for the swimmers, whatever the type of course or wind speed.
