At any given time, 50 or more vessels, ranging from massive cargo ships to small fishing boats, are motoring off New Jersey's 127-mile coast from New York to Delaware.
The smaller vessels often travel at just a few knots per hour, while larger ones run to 20 knots (23 mph) or more.
Little wonder whales sometimes crash into one of them, receiving what amounts to giant-sized headaches or fatal blows.
