okay.........deep breaths people!
Doing a liveaboard from Fla to Bahamas does not mean you are going to be killed by a shark. That particular liveaboard (Shearwater run by Jim Abernethy) does nothing BUT specific trips for people to encounter tigers, hammers, etc. It goes to a specific area and chums the water to draw them in for adv photographers, videographers, etc. They are the boat used by people like Howard and Michelle Hall, National Geographic, and others to get all those wonderful videos you see on tv. They have been doing this trip for a long time, every week and usually sold out months in advance. This is their first serious incident. Condolences to the family of the diver, but he signed up for these dangerous dives knowing all about the dangers.
Other liveaboards from Fla to Bahamas do shark feeds usually one afternoon during the trip. The Bahama islands have lots of sharks and you can see them on any dive, just not
usually the tigers or hammerheads. They don't pay much attention to divers. It is a thrill and an honor, IMHO, to see sharks in their natural habitat. I love them and I am hoping to see some again on my trip on the Nekton in April.
My opinion on shark feeds = been there, done that, it was interesting but don't plan to do it again, probably. On our last Nekton trip we had sharks at the Big Hole, dozens of them on Wed. They just swam around, realized we had no food, and didn't pay any attention to us. On Thurs there was a feed - they sharks started swimming faster, very spun up, knowing it was feed day. We all kneeled in the sand and watched them fight for food for 10 minutes, then they started darting around, still spun up. We all got off the sand and swam back to boat with the sharks following us, still swimming fast and darting in and out between the divers. We all did a safety stop behind the boat with the sharks! It was a bit unnerving but no one got bit! The sharks just wanted more food. We all did our 3 min stops and got back on the boat, the sharks left.
So what does this prove? It proves that sharks are smart enough to know that: the first day divers swim around with us and no food, the second day they feed us, AND they know that the feeding is done at a specific spot, when food is gone the divers leave. Was it interesting, YES. We could definitely see a behavioral difference in the same sharks we had been swimming with the day before. (all the DMs from the boat were in the water and carrying poke-sticks).
The focus of these trips are NOT daily shark feeds or chum encounters (like the Shearwater). The Nekton, Blackbeards, Explorer, etc. boats do dives in the Bahamas with maybe one shark dive.
