AFAIK there is one project that tries to remove all "unnecessary" bits, although it's just a model: http://www.youtube.com/watch?v=1tEw_mlUh7g&feature=player_de

  Cool! Thanks for that link. That's very close to the ideas floating round in my head right now. Something very similar to that, a super efficient "kite" (think more like the SailRocket sail or a glider wing), "tethered" underwater using this 50+knot cavitation tolerant foil technology. I'm guessing it'd need a fair bit of "stuff" to get it up to the speed where the wing and foil start to operate effectively, wich might either be jettison-able floats/spars, or perhaps some technique where it gets launched/towed up to speed - kind of like how big wave surfers use jetski tow-ins to get on to big waves at speed - I wonder what the world record rules would say about a 70+knot "sailboat" that need to be towed up to 50_knots to work at all?
