    100% foiled races?

    Kitefoil gold cup has been doing it for years...SailGP can do it......Last AC they did it....... so I say yes

    Boats and foils comparison

    I mean thickness and chord would be a lot different

    Team NZ

    Can't help but wonder, if they go better upwind with the boat leaning to windward.... or the foil not fully articulated down, so the foil is pushing the boat into wind?

    ....... Unless the foil design is for super cavitation.......

    I would guess... torpedo= strong wind fast foils.

    One thing is certain.... those foils are so different, that someone got it right, and someone got it wrong for sure.

    THE IMOCA thread, single/double handed & TOR

    a recumbant position is lower CoG than bent over a cofee grinder...

    Why so nose up on foils - IMOCA

    Maybe your onto something ..... If the keel horizontal axis cants, there is another control....

    I can't help but noticed the uncomfortable hunched over position the grinders take when trying to grind the coffee under the cramped cockpit..... surlely if this was about the long game then boats would have installed a seated / reclined cyclor. More power / more comfort / more control ( hands are free ).... or is leg power outlawed? I would have thought some kind of reclined seat with pedals on the bottom.... maybe even a hamock style that is free rotate with heel angle to keep the driver upright.... or do they not use the winches for much ?

    Depends which boat you talk about I guess. HB has a curved foil, and I very much doubt that it has lift vectors like that on the HB foil. They go vertically up - not sideways.

    Yeah, but the foiling boat doesn't need more righting moment.... it could benefit massively from any type of additional stability however. Who knows how it is setup, but I would guess from the pics, the keel fin is doing more than supporting the keel, and it's helping get the boat out of the water like a surface piercing foil but in reverse.

    I wouldn't be so sure about that....... Keel fins are designed to go straight through the water, and will provide lift if they are not. If you look at the nose up angle the boat is at when they are foiling, that means the keel fin is also at the same angle of attack upwards... and the bulb also, producing some amount of vertical lift. not as much as the lifting foil, but it would be providing some kind of balance to the platform in either case, more of a tripod than a two legged chair balanced by the wind in the sails.

    My forecast, nothing under 50 feet will beat Maverick.
