I've fished down in Islamorada 4 or 5 times and the boat guides always talk about the dangerous flying rays. This lady is lucky because the boat was stationary. If it had been cruising along, she would have been toast. While only 2 people have been killed, there are loads of near misses.
Stingray Tries to Hitch Ride on Boat in Florida
by Fran Golden
An Illinois family vacationing in the Florida Keys got a big surprise when a stingray jumped onto their chartered pontoon boat.
The spotted eagle ray leaped onto the 26-foot boat in a channel in Islamorada and struck Jenny Hausch, 39, in the chest, reports the Miami Herald.
The collision with the five-foot, 200-pound creature knocked Hausch to the deck, but the stingray was apparently equally stunned.
