I am trying to show some pilot/aero engineering co-workers the developments in catamarans (they only seem to know of the Hobie 16 when it comes to cats) over the past several years. I am specifially looking for two pictures that I have seen posted here but now I cannot find them. One is of Ben Hall's Wing Sail and the other is of the foiling C cat, sailing up on the foils.

If anyone can point me to those threads/pictures I would be most thankful. I have tried the "search" function above with no results.

Thanks in advance, Tim.
