I came across this Russian video while searching for something else. It conveys, as few other videos have in my experience, the raw power of the sea when Mother Nature gets her dander up. I recommend watching it in full-screen mode.
It brought back lots of memories of my time in ships and small craft off the Cape of Good Hope and around the southern coast of Africa, where the Agulhas Current makes the area the so-called ‘Home of the Rogue Wave‘. (The first explorer to round the Cape, Bartolomeu Dias, named it the ‘Cape Of Storms’, with good reason. The King of Portugal decided that was bad public relations, so he renamed it the ‘Cape Of Good Hope’. On a calm day it’s absolutely beautiful – in 1580 Sir Francis Drake called it ‘the fairest Cape in all the world’, and in good weather I won’t disagree with him. On a rough day, though . . . )
