    All of the disadvantages of a boat combined with all of the disadvantages of a float plane. I like it.

    Looks like the precursor to the wing in ground effect boats, the Lipschitz based designs; Ekranoplan, Airfish, etc...

    kinda cool - once airborne the drag effect in the water s limited to the outboard motor drag - and I suspect the drag from water is worse than drag from air simply because of the density ) all other elements being equal.
