Cmon guys....
The click bait called 'Untold Story' is just that... 'click bait'...
Just on a couple of key issues:
1. Benny L hated Bertrand, probably for good reason.
2. The keel winglets and bulb enabled lower CG and higher RM under the restricive draft rule. The endplate effects probably materially reduced induced drag
3. The light and minimum WL design enabled (relatively) good SA:WS
4. Dennis went the wrong way down the last run - thicker boundary layer with rougher water near the spectator fleet. And set the wrong spinnaker for the TWS and water roughness, as well.
5. Statistically. the AII team had a predicted gain on that run of ~ 40 secomds, from their previous racing against Liberty.
6. Whilst Peter van Oosanen was incredibly important to the tank and numerical modelling work, Ben L and his guys made every final design decision.
7. Post Cup simulation for downwind, including keel wings with typical heave and pitch, saw positive results versus lower wetted surface design with conventional keel....which was the opposite of their initial work without pitch & heave....
8. The fuckin video is a piece of shiiiiiite.
Trust this informs & helps..
