Don't get me wrong, I do like the idea. I also liked the super ferry idea but that didn't last long. But although electric engines are pretty silent, this thing will make a noise at that speed over the water. I see one or two other issues as well, but don't want to give info to the naysayers. One of my regrets was never taking the hovercraft across the Channel to France - and that thing did actually "float" before it set sail.
PS. The disturbance of the surface water will be heard by a whale a long time before the craft gets there as the speed of sound in water is much faster than the craft. Leilanidude may have a different opinion as he has other ideas about physics and water.
