think that may have been the motivation to create the waterjet-pack
Attachment 41986

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

And both contain endless cavities to pour money in just for fun, what's not to like

That is too cool!!!

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.
