Shark attacks are very rare. Sharks usually feed at night and during twilight. Sharks are curious and may approach you. I have dove with white tips and hammerheads. After investigating you, they recognize you are not food and move on.

Sharks detect the electrical impulses in your muscles and bodily fluids like blood and urine. Do not confuse them with excessive splashing or attract them by fishing or chumming.

Sharks attack by first biting the victim once. They then let the victim die before eating the dead victim. If you are bit by a shark, if you can get to safety, you should survive.

If you are out with 2 small children, don''t both go in the water at the same time. And don''t get offshore and then have one of you searching in the sun for the body of someone who may have bitten by a shark. Be a responsible parent first. A bucket on a line works just as well for cooling you off, and if you really need that much cooling off, then think of the kids and how hot they are, so why should you be out there? (And I have been around kids circum with their parents.)

No matter how much you are scared of them, no matter how you want to blame "dive tours" for feeding them, remember - sharks will not jump into your boat to get you. They will eat what is convenient. I have had a 15 foot thresher circling a boat in the doldrums for 3 days. He lived, evidently, on leftovers we had to throw overboard, but we were not "feeding him", we just didn''t have the wind or fuel to move. He never made a move to jump on the boat. Don''t go for the evening swim together because it''s "romantic" and you will have no problem. I have known people who have sailed with their kids everywhere, the Atlantic, the Pacific, did a circum, etc., but never did I hear a worry from the parents about sharks eating them because they wanted to go for a swim.

I used to sail a Laser off of Myrtyle Beach,SC. Saw a lot of sharks dolphins and turtles. One shark 3'' followed me about 6'' behind for a few minutes. Once while I was circling a big ball of mullet a 4-5'' shark jumped clear of the water and went into the middle of the mullet ball. I didn''t know that sharks jumped until that happened. Once I saw a very large fin that almost scared me to death. Fortunately it was going away from me. Overall I saw the most sharks within a 100 yards of the beach. Usually they were following schools of fish. My wife saw a 12'' hammerhead inside of the breakers!!!!
While scuba diving in the Bahamas I was impressed by how curious and sneaky reef sharks can be. One cam up behind my buddy about a 6''er went to within 2'' of his head and then left. On the surface he confessed that he hadn''t seen the shark. On the same trip as was near the surface and watched a larger shark approach a couple from behind. It checked them out closely. Back on the boat they were completely unaware of the close encounter. I''ve never had one show the least aggression to me. But a buddy had one take a speared fish from him. As he was swiming away it bit his fin. I didn''t believe him until he showed me the teeth marks on his fin.

I know it''s late, but I had to work the freaking late shift again at the boat store, and it looks like I may be doing so til the end of time or the finding of another job.

Anyway, there are plenty of sharks off the Carolina shore (like Myrtle Beach - I used to live in Little River). Just as there are many sharks in any coastal area. As stated above, just because you don''t see them, don''t think they aren''t there. The most aggresive I ever saw was, believe or not, a blue tip that followed our boat from just out of the jetty til it lost interest. This was right after a week of tumultuous storms in the area. I only hope it didn''t turn back and bite a swimmer. Unfortunately, and against my wishes, others aboard threw him bits of meat and such - there were a few onboard who did throw morsels of their lunch overboard to tempt him, and he devoured every one. There are many, many breeds, and many temperaments. I have been circled for 4 days, while becalmed (later we learned to take more fuel), with nothing more than a languid glance from a 15 foot thresher. He appreciated the leftovers thrown overboard - became like a big pet that ate the leftover chicken and broccoli and such. Now, when you are 1,000 miles out - there is nowhere to put your garbage! He was persistent, I must say, obviously responding to the resonating sounds from the boom, but never ever made an effort to attack while I was on the transom washing out the pots from dinner. Needless to say, I didn''t get the nerve up to do this til he had been around a day. After a day and a half, my thought was, if he eats me, who is the one throwing him the grub, cause the others were too afraid to even lean over the gunwale, he won''t get anything else to eat. I sent that vibe out, and it worked, I guess, cause I was the one who volunteered to wash out the pots and he never made a move on me. Believe me, I was barely hanging out there, and always ready to jump back. On the afternoon of the fourth day we actually got to set some sail. He left. I saved some of my chicken and broccoli and rice that night, covering it with plastic wrap, hoping he would come back. I was awakened for my watch - the midwatch, my least fave. I took my bowl to the cockpit, ate some of it. It was a full moon. About 45 minutes into my watch - there he was. He stayed with us the next 2 days, only coming close at night, for some reason, getting a scream or two from the other crew member (a ''well-seasoned sailor'' who wrote, at the time, for a prominent sailing magazine). So, even the most vicious denizens of the deep can be tamed for a bit by broccoli, I suppose.

NOT recommending ever tossing anything overboard for the feeding of sharks, just sharing my story of life at sea.

Fair Winds,
and remember, this is their home,

Yeah, try pages 154-155 Nigel Calder''s "Boatowner''s Mechanical and Electrical Manual" for a photo and description of the No-Strike device (Island Technology, Cherry Hill, NJ). Calder also recommends proper electrical grounding (page 150), which is also worthy of some serious study.
