These waves are only a few inches high in the open ocean but they are
traveling hundreds of miles an hour and are miles between the crests. They
have only rarely been observed in the open sea and then only in calms where
they are not masked by other wave action. This is one reason why there is
little warning.

When the waves reach shallow water, the enormous energy of their high speed,
and the tremendous volume represented by even a few inches over the very
long wavelength, translates into very high waves as the wavelength is
shortened by the shallow water.

Curiosity? Should not the Tsunami wave affect a high seas cruising
boat? I have seen no mention of it anywhere; but would have thought
there would be some damage to boats at sea. ??
