ISAF offers resources, for reducing your risk of a shark bite, and instructions for what to do, if you encounter a shark.

Great Whites don't bite you - they swallow you whole.
Case in South Australia some years ago.... they didn't find the diver - but they did find his weight belt still done up - that the shark had spat out.

NOT TRUE!
Most great white attacks aren't even fatal - never mind 'swallowed whole'.

There are far more survivors, of white shark [Carcharodon carcharias] attacks, than there are fatalities.
The International Shark Attack File reports [1] that: fewer than 17% [59 vs 292] of the unprovoked attacks [351 total], by this species, have been fatal, since records began in 1580.
Scientists aren't sure why great whites usually spit humans out, after a 'sample bite'. Some think it might be that we don't contain enough calories, or that the sharks are just curious, but can only investigate with their sensitive teeth and jaws.
White sharks have been observed delivering a sudden ram to their prey, followed by a bite, and a side-to-side head shake, to tear out a chunk of flesh.

That's what I was going to say. One known incident in decades of ocean crossings by tens of thousands of boats. Sounds like better odds than crossing the street.


I'm afraid that lady was simply spectacularly unlucky. Her number came up.

No need to shout.

As your links suggest they are talking about juvenile or what we would call 'Lesser Whites'.
In southern Australia we have no bullsh1t fair dinkum Great Whites.
They swallow you whole.
I saw this one dead
https://www.pisra.com.au/churchill-i...land-sensation
and I saw its mum alive.
NB don't go swimming anywhere there are seals. They swallow them whole as well.

As my first link indicates "Most great white attacks, [of any kind] aren't even fatal [<17%] - never mind 'swallowed whole'.

The second link, about juveniles, was interesting, but irrelevant, to your false claim.

Are you referring to Eric Nerhus?
On the 24th of January 2007, an abalone diver was attacked by a Great White Shark while diving with his son off the south coast of NSW. Eric Nerhus suffered horrific injuries after the shark swallowed him until his entire upper body was inside the animal's mouth. Eventually the shark spat him out and he miraculously survived.

No - he was spat out because he managed to poke it in the eye.
The nasty buggers live in SA , Bass Strait, and Tas.
There is a reason the 'swallowed whole' ones don't get in the stats is that they have been 'swallowed whole'.

Re: Shark Attack - Swimming Offshore

Recent articles have sharks making a comeback here in Long Island Sound in the northeast U.S. Which has me adjusting my swimming routines. Because my local waters have a high nutrient content the visibility is limited. So instead of staying in the water for thirty minutes to an hour like I use to. I'll be limiting it to quick cleaning of the dingy bottom.

This reminds me of a mouldy, oldie cross examination tale:
“Police officer, on the witness stand: I saw the defendant bite off the victim’s ear.
Defense lawyers: Well, sir, isn’t it true that you were in your police vehicle, and were in no position to see the defendant bite off the ear of the victim?
Officer: Yes, I have to admit, that is true.
Defense lawyer: Well then, how did you know that my client bid off the victim’s ear?
Officer: I saw him spit it out.

Re: Shark Attack - Swimming Offshore

For spectacular, in South Africa we have the inverse of what people understand when they hear “great white shark attack”

That’s when our Orca attack and eat the great white sharks

Thank heavens Orca don’t (yet?) have an appetite for humans because THAT would not have many survivor stories.

As to the risk of shark attack while swimming near yacht, it has to be very low, but those odds accelerate exponentially when:
1. You clean fish or dump food waste overboard.
2. You urinate in the water while you swim.

I doubt that sharks are attracted to human urine.

Re: Shark Attack - Swimming Offshore

I've always had more shark concern when swimming at anchor than at sea (still has not generally stopped me most places). Case in point is Cid Harbour in the Whitsundays, we were anchored there, and swimming, about a month before the dual attacks that took place. In the aftermath there as an article that said:

Quote:
“There was an open letter to the Queensland premier from a local arguing against lethal mitigation, like drum lines, when educational signs and communication from tourism operators would be far more appropriate. The locals already knew not to swim there.

In the open letter, local woman Kellie Leonard asked that Queensland Premier Annastacia Palaszczuk visit Cid Harbour to get a better understanding of the area. “Commercial live-aboard vessels and day tour operators never visit Cid Harbour because it is well known as being not a good swimming area and is no good for snorkelling or diving,” she wrote.

“It would be a lot easier to advise tourists not to swim in the areas with mud bottoms, rather than scaring people by seeing sharks getting caught on drum lines, in what will always be a sharky area.” She added that sharks play an important role in the ocean’s ecosystem and that rather than killing them, Cid Harbour should be made a no swim zone.
I guess we never got the word, nor the idea that boats chummed to attract sharks in Cid Harbour (truth of that allegation unverified - sounds like 'my cousin had a friend who saw...'). And I have never before heard the assertion that mud bottoms are an indication to stay out of the water.

I know a number of commercial spearfishers who work on SCUBA. Men and women.

A month or two ago one of them, now in his late 60s, told me he had basically watched 2 people die due to SCUBA-related problems during his career but that industry-wide it is believed that there are twice as many fatalities from sharks as from SCUBA problems. He dives to 180 feet on a single tank of air to find fish.

They all tell stories about fighting off sharks with a spear while at the surface with a bag containing their catch (i.e. dead and bleeding fish), waiting for their boat to come pick them up. It's routine for them.

It's dangerous work. They are all independent and so they're not regulated by OSHA and they aren't included in the DAN statistics. And any shark attack statistics you find will have a note somewhere stating that they don't include commercial fishing.
