As a tourist, when I told a friend I was going to AC for my first time back in 2004 one of the first things she said was "the reef is only 1/2 mile offshore but it would be suicide to try and swim out, way too much boat traffic". (her last trip there was in 1998!)
That was all the education I needed. To this day I cant get much over 20-30 ft from the end of a dock, just isnt worth the risk.
I see Elberts point. I sypathize with the injured tourist, but I cant imagine getting very far out. Common sense should apply, but we tourists do desperately need to be educated. I was and it stuck!!!
