Frenchie,

Since you are obviously interested in foils and speed, maybe you would like to know that Aldis Eglajs (the designer of the Catris) also believes that in the future supercavitating foils will be used in the fastest boats.

He maintains contact with ressearchers of the former soviet union in this area and wants to build an offshore trimaran with supercavitating foilers in the future.

Tom Speer's site is excellent, but his goal is to make a smaller cruising foiler for recreational purposes. He likes speed, but he is not exactly after record breaking speeds.

Cheers,
