 Sharks are
a highly emotive topic, especially when combined with surfing or paddling, but here in Cape
Town we have to face the fact that we share the water
with them when we paddle.
This incident
is published to illustrate that an encounter even with an aggressive Great White
need not end badly. We also asked shark
researcher Allison Kock what paddlers should do when faced with such a
situation.
Joe Kearney's Story

On Saturday morning, 12 May 2007, I set off
with legendary Peninsula paddlers Ian Trautmann and Rory Cole on a longish
paddle from Hout Bay to Kommetjie as part of our World
cup training.
It was a peach of day, absolutely no wind,
beautiful blue skies mirrored by an inviting glassy blue ocean.
Dolphins
We paddled towards the Dungeons surf break
stopping to admire the huge sets rolling in and then headed south towards
Kommetjie. The conditions were glassy with at least 10-12 foot swells. About 2km out to sea from Dungeons I suddenly
noticed that we where not alone and shouted to the guys I had seen something
beneath my boat. My terror turned to instant relief as I saw a friendly dolphin
fin broach the water a couple of metres ahead of us and then a few more around
us. We admired the dolphins which were the dusky type, quite common to our Cape waters.
 Shark Incident - 2km off Dungeons
Rory suddenly exclaimed that the dolphin
swimming just to his right below him was definitely not a dolphin - in language
I would hate to repeat [Editor: Rory denies any use of bad language!], and that in fact he was certain it was a Great White. We asked him if
he was 100% certain and he said he could see the whole shape and it was
definitely a great white at least 3 m in length. We continued paddling closely
together as a pack, cautiously, hoping it would lose interest. I must add
luckily for me I happened to land up in between Rory and Ian which certainly
gave me an increased sense of security!
Mock(?) Charge
The next minute there was a commotion in the
water and all I saw was a tail fin do an about flick at high speed,
milliseconds before it would have come crashing side on in Rory's ski. Rory
said it happened extremely quickly, but he had seen the pectoral fin coming
straight at him and that the shark had turned from its attack at the last
minute. Fortunately for us that was the last we saw of the shark and we
continued our paddle to Kommetjie and back although I must add every time a
seal breached the water there was a slight air of uneasiness amongst us.
Silver Blades
Our theory is that we must have paddled right
over a school of dolphins feeding on yellow tail or some other shoal of fish
and the great white was trying to scare us off. Rory was paddling with silver
blades, and another plausible theory is that the Great White mistook the
shimmering of the blades for a small gamefish. Either way our advice to sea
paddlers is rather don't paddle with silver blades, as this Great White's line
of attack appeared to be directed straight at Rory's blade in the water. You
can be assured that Rory will not be paddling on the sea with those same blades
again!
New Scientist Magazine: "The Handy Guide to
Shark Body Language"
In the 28
April 2007 edition of New Scientist Magazine, there's an article
about a research project that has catalogued threat displays in 23 species of
shark.
Two such
threat displays, associated with Great Whites, are swimming slowly and rolling
over onto one side, and mock charges.
Clearly
this shark was not pleased with the surf skis.
So much for recognising the threat display - but what do you do about
it?
I forwarded Joe's email to Great White Shark researcher Alison Kock and asked her for her comments.
Alison Kock - Great White Shark Researcher
The shark spotters have had a few sightings in
the Noordhoek / Kommetjie area this month and last (i.e. April/May 2007) for
the first time since they initiated the programme there last year. If you want
more information on this you can contact Andre from the shark spotters at
0846590453.
Marine & Coastal Management attempted to
tag sharks in the area two weeks ago as we have two receivers in the area, but
had no success, they never even saw one. Our knowledge of white shark occurrence
in this area is poor.
Change-over Time
However, this time of year is what we call 'the
change-over time' where major changes occur in shark habitat use from summer to
winter areas.
Many people are under the belief that if you
see dolphins then there are no sharks, when in fact there is evidence that
white sharks attack and eat dolphins. It's been recorded that large sharks
follow whales, opportunistically feeding on dead or vulnerable calves & the
same may be possible for dolphins.
If you see a shark - stop paddling
With regards the silver blades, it is very
possible that the silver colour may attract a shark's attention. The movement
may also be the attraction. I would advise that if you encounter a white shark
for you to stop paddling as it's very possible that the movement of the kayak
may act as a trigger.
 Fishy looking blade?
To give you an example: many tour operators use
seal decoys towed behind the boat to illicit breaches/attacks. The sharks
launch full out vertical attacks on these moving decoys. However, when the
decoy is stationary it does not illicit the same behaviour from the shark. The
shark may approach the stationary decoy, but not launch a full out attack.
Interestingly, a scientist decided to test shape discrimination abilities and
towed a square cut-out behind the boat and it was hit almost just as often as
the seal shape while it was being towed, so it pointed to the fact that it was
actually the movement of the decoy and not the shape that mattered so much.
Recommendations
It seems
then, that silver blades may not be a good idea. We recommend painting them a different colour
(mine are neon pink for safety/visibility reasons and I'm just hoping that
sharks aren't attracted to neon pink!)
And, if you
do spot a shark, it may be best to stop paddling and just sit still on the
water for a few minutes.
I recently
replaced the rudder on my ski - the new one is silver-ish and I asked Alison
what colour I should paint it. "Of
course there is no scientific proof on this," she replied, "but my personal
choice, based on observation with the sharks, would be to choose a dull green."
Paddling - an extremely safe sport
Either way,
the chances of encountering a shark are extremely small, and the chances of
being injured in an incident are infinitesimal.
We know of only one person on a surf ski being injured, ever, and that
was many years ago off Durban when a paddler stuck his feet over the side while
he was waiting for a buddy to come out through the surf. A small shark bit one of his feet, causing
lacerations...
You're far more likely to be injured while driving to the beach - take care!
