i hang out every summer at English Bay beach with my friends, and the funniest thing happened this year. A speed boat was jetting through the water about 500 metres or more from the shore. I saw these tourists and kids hanging around at the water....i knew what was gonna happen, and i did think about warning them at first - but then i decided not to and took my camera out and recorded the whole thing.
the boat had created a wake in the water, those poor people by the water didn't see it coming at all. tiny ripples soon became a 1.5 metre high wave that got people running away screaming...
a few fell, and everyone got wet.
it was like watching a mini-tsunamis.
