In the mid-1960s, the Soviets were testing something they called an ekranoplan, which is essentially a hovercraft. It's a hybrid of a boat and an airplane (which is more generally called a ground effects vehicle), floating on water but with wings to provide lift. At speed, it skims along up to 20 meters above the ocean's surface. The idea was that it would act as a high-speed transport, hauling equipment long distances at airplane speed, but with far greater capacity and fuel efficiency than any cargo plane.
I've seen some awesome tiny turbines lately, one could probably do something like this with EDF as well.
