'build it" "and they will come"

-- from Feild of Dreams ;]

They have done just that with the Am Cup --AMAZING SHOW !

The Am Cup certainly has inspired many people.

Wing sails are not practical yet --though it is a matter of time before someone builds a foldable -raise -lower version.

Stability is the problem with foils --the crews work very hard maintaing it on the Cup cats. So --the need for a more stable simpler version is needed --perhaps angled outward ?

The INSTABILITY of 2 T foils on previous C Class cat design in example.

Perhaps 2 smaller foils on each hull for and aft for balance --not sure if a trim tab would be needed aft or not.It would be great fun building and experimenting though.
