...this is the reason for the tapered surface-piercing foils as seen in the old Icarus I photos from the 1970s, and now the 36 foot Spitfire biplane foiler from Perth. The question that I see is- can I buld a modern tapered shape that will avoid some of the disadvantages of previous shapes...
I once asked Aldis Eglajs about the Australian Spitfire. All he commented is that progress is very slow and that the Spitfire is 99% the same as James Grogonos last Icarus concept, before 1987. He implied that this type of design works, but has some conceptual limitations.
Are you spending your time in a dead end? I don't know enough for my opinion to be relevant, but I know there are many concepts to investigate and very few people doing the ressearch, so go ahead!
Oh, yes: there was a big boat called Bumblebee some 25 years ago. I think it was South African.
Cheers,
