Why not commercial ground-effect vehicles (i.e: "Caspian Sea
Monsters") that theoretically could make transatlantic trips
at approximately .5 mach economically, safely and luxuriously?

Those ae fine in low wave states but the notion of doing that
speed in the North Atlantic is not attractive, a large wave
could have serious effects on your health.

I could be wrong, but aren't these humongous vehicles capable of
climbing out of ground effect?
