The Secret of Sailing
I have updated the upcoming book The Secret of Sailing in accordance with the update of The Secret of Flying with the computational results in the 2009 article The Mathematical Secret of Flight confirmed with better resolution.
Altogether we presents the first scientifically correct explanation of the generation of lift L and drag D of a wing or sail with L/D > 10, which is needed to make both flying and sailing possible in practice.
It is expected that the new explanation will open to improved designs of both sails and keels.
Notice that the new Americas Cup design AC45 (preparing for the AC72 in 2013 match) has a main sail in the form of a wing.
