    Now that Computer Control is cheap and reliable, shouldn't their be more fully submerged rigs like the USS Pegasus.

    I hear fully submerged is a lot more efficient, since it doesn't have lots of wing breaking the surface at a angle and mostly just causing drag.

    Aren't you talking about a Moth or kite boarding on a foil?

    Who wants a computer?

    Does the AC45 rig meet your criteria? If a control system was allowed it should be quite adaptable.

    Not a T foil, but still submerged.

    Google Boeing Jetfoil. Really can't be viable here in the US with the NTSB knowing what happens during a "crash & burn". Buses (including school buses) are soon going to be the same way.

    I was in Hawaii when those were doing ferry duty inter-island.
    Still kick myself that I didn't ride one.
    I heard stories about hitting whales, but never saw a report.

    I looked the up and only one listed inactive due to an accident, #2 in 2013. Another was simply inactive while a number were listed as laid up in some shipyard.

    Personally, I'd like to see work progress of commercial ekranoplans.

    The one I didn't take was pulled from commercial service around '75.

    Realistically, ekranoplans are also niche market. Fun, but only good for hauling fruit or troops.

    Might make a nice rich man's toy. Better accommodations and more places to land than a plane. Faster than a boat.
