    What about a swat? Aren't those less draggy/displacement than kayaks that are semi lifted?

    That's what I'm finding in my calculations right now Doug.

    It's similar to my design concept.

    What I'm thinking now is a variably inflatable pod.

    Zero buoyancy at start up for stability, inflation at take off velocity, then slow deflation as speed increases and foil lift builds and the AoA flattens, drag reduces.

    I'm starting to realize 125 watts sustained just isn't enough for a steady state, long term flyer.

    Too bad, I really thought it possible.

    Maybe for a 95 pound kid on a 25 pound vehicle.

    Back to the drawing board.
