norcal, I disagree that surfers would want chumming 27 miles away - these predators move great distances and enticing their behavior to associate food with boats/people could be bad for surfers.
A few years ago PBS made a show on sharks and a segment of the show specifically dealt with Tiger shark attacks in Hawaii. The local authorities caught and tagged sharks only to find that they migrate great distances. The Tiger shark which attacked on one beach could be miles away the next day.
