I just came across news of this accident from 2012 during the blacktip shark migration. He was on a 20 mile downwinder heading south from Singer Island. He was about a 100 yards off the beach near the Palm Beach Inlet when he collided with the shark, more accurately, the shark's teeth? He indicated he had noticed a group of about 20 sharks in the area prior to the encounter. It looks like it was a pretty small shark fortunately and one that didn't come back for seconds. He had some connective tissue damage and ended up having heart surgery as a consequence of the accident. A minor accident ended up having more serious overtones as a result. More about that
in the links below.
Continued with consideration of other attacks in the area:
The vicinity of the encounter.
