In 2013 I can't suppress a feeling that it was staged. Boat hydro/aerodynamics is well defined, so they (Oracle) knew in advance how much handicap they can give away. When megabucks are involved they had to make it entertaining.
Look at the polars posted by top racers and compare their VMG with the AC50s. Assuming the overlay is correct on the broadcast the AC50s rarely exceed 20 knots VMG upwind and downwind in 6-7 knots wind. They are faster on a reach but there is not much between them elsewhere. In light winds AC50s spend a lot of time in sub 10 knots VMG when tacking where I suspect Nico or similar fast rider will be faster up to speed after tacking.Tone wrote: ↑Tue Jun 13, 2017 4:21 pmYou're wrong.FrederikS wrote: ↑Tue Jun 13, 2017 1:56 pmOn an upwind downwind course they would probably be equally fast. The VMG up and downwind look very similar to what the top HF racers are doing if you look at the VMG in the races with sub 10 knots wind. Even with the reach start and finish I think the top racers will be fine, the AC50s peak at around 40 knots on a reach in light winds.
I think the key in answering my questions is this comment from gbrungra, thanks gbrungra! I didnt know that they have published these statistics.gbrungra wrote: ↑Wed Jun 14, 2017 1:10 amFound a polar for the 2013 America's Cup:

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?
