On what do you base your silly assumption, Nil? If you had ever seen a
30 meter wave you probably die of fear but assuming the worst and you
lived you wouldn't need to ask.

Your little insult to cockle shells would be reduced to a debris field
of plastic waste rather than the offensive agglomeration it is now.
