According to The Register, the new fins will allow a diver to swim at a sustained 2 knots.

According to the first link returned by Google for "How fast can a great white swim": A great white's can swim about 20 knots -- in bursts. But, they usually swim around 1 or 2 knots.

So, the question is, who's got a better burst, a diver or a hungry shark? And who do you think can sustain that for longer?

Not too long ago, the Cincinatti Bengal's wide receiver Chad Johnson raced a horse. If anyone ever wants to race a shark, please let me know. I'm putting money on the shark.
