How far is too far? Most (about 85% of fatal shark attacks occur in less than 3 FEET of water. Of course there are exceptions. When I was a kid (about ten years old) I witnessed a fatal shark attack off the tip of Miami, FL. We were sailing in a rather large yacht owned by family friends and this girl was snorkeling near the edge of the continental shelf where sea life teams and a Great White just swam up and bit off her leg. She died of shock. I was about 50 yards away and heard her screams. I got the binocs on her just in time to see the water boil and turn red. Pretty awful. I saw the fin of the animal as it broke surface on the way out to sea. Triangular shaped is Jaws. A few years later the movie came out and I didn't go near the ocean for another four or five years.
I'll be in South Walton in about a month.
I'm not telling my kids.
God, that was awful. For a ten year old to see.
