    I have just noticed an interesting thing in the second pic...
    It appears that the water spray from the leeward foil impinges against the ama and gets deflected downwards. In that case an additional lift force should be created at the leeward ama, augmenting the overall lift force, diminishing the heel angle and (I'm guessing) the hydrodynamic efficiency.

    Does someone know (there are many well-informed people in this forum... ;) ) if this is a true effect or is it just an illusion produced by this particular viewing angle? And if it is real, do you think it was an intentional feature of Hydroptere's design or was it just a lucky by-product of this particular configuration?

    Ok Doug, I will transfer this to the other thread. Please do not reply me here, let's not create confusion. ;)
