Scary...but that reminds me needs for

100% obvious emergency SOS signal (distress ) on the water.

We in our windsufring family did such aragements regarding special signs but could be
nice to have one universal recognizable from kiloometers away that person needs help now
Unless I am missing something and there is already such hand singnal

From what I remember crossing your arms over your chest indicates you need assistance. I could be wrong with this though. This video also indicates the need for good health insurance.

For as long as I can remember the in water distress signal promoted by surf life saving has been to hold up one arm above your head and wave.

In that case even a distress flare wouldn't be much use - you need two hands to operate them.

Fortunately if you're in the water for long someone usually comes by to see if you need help.

Surely not, how would one tell from a distance if you have your arms crossed or just in the water.

wrong...
possibly after some time in the water you don't need any help any more
possibly after some time your body will afloat by itself
...
this sort of thinking possibly attributed to drowning of asylum seekers
...
it is so obvious ( SOS) that don't need further consultations...
everyday experience is that guy with broken something in the water ( usually in extreme weather conditions could float for hours before somebody decide to do something...

excellent... we have consensus what the distress signal is...

-waving all six hands over head when sitting on the boat
-arms crossed on the chest for divers
-one hand waving for surf savers
-middle finger -kiters favourite sign
- I forget.... call 000, 111 or 911 on your waterproof iphone

You are probably right. Waving your arms around is a better way to get attention.

I have been thinking about emergency signal for a little bit. The best option I could think of was an emergency whistle. You would think there would be a smoke flare that you could use with one hand but I havent been able to find one.

I think your also supposed to have a closed fist when waving so as not to be confused with a friendly hello.

The internationally recognised distress signal is waving both arms so as to cross over hands at face height. Hmmm - imagine doing actions for YMCA (yes a bit ghey, but anyway...) Make the "Y" . Now make the "M" without dropping your elbows. Repeat.

That has been the international distress signal for god-knows how long as waving one arm can be hello. It also is about the most movement you can make so is easily recognised at a distance

How can they not teach that in WS and kite school..........

There is only one signal to remember... the "ok" signal - fingertips touching your head so that your elbow/arm makes an O shape.




All other signals are "get the F*** over here".


EDIT: the ok signal can be used as a question and as a statement, and you can see at least about 100m away.

I don't know where you sail but I am often being asked if I'm OK when I'm just waiting for a gust to waterstart!

We do need a well recognised one handed signal. If one arm is really injured as in this case you are not going to want to wave it above your head. Also it is a good idea to hang onto your gear with one hand so it doesn't drift off leaving you without flotation.
The one handed wave with clenched fist sounds like the best idea so far.

Floating face down in the water is universally recognisable as a distress signal.

One hand raised with clenched fist - waving's not really the go, but hard to resist when trying to get someone's attention.

Also the 'ok' by touching your fingers on your head making a circle can be useful (and won't waste others' time) if you're not in trouble.

Use whatever you can, if you can sit on the board wave both hands if practical. When I had my little mishap last year was either holding on or swimming so two hands would have been out, hell, wave your helmet, rashy or harness if you can, I'm sure that wouldn't be confused with hello.

Kiters have this edge over us for sure
They could always drawn their yellow red dot polka boardies over their head and that is umistakleable sign that kiter is in distress
gets attention too

You wouldn't think water was that hard, but then 10 metre tower divers who hit the water at sqrt(2 X 9.8 X 10 ) m/sec = 14m/sec = 50.4 kph often use wrist braces just in case they don't break the water exactly as planned. ma was doing 75kph!

so maybe we should punch the water with close fist when landing ? Is it safer ?

the speed of a punch thrown by an average person :
40-50 mph, hits with 200-300 pounds of force,
and has a reaction speed of .2 to .3.
Bruce Lee was supposedly clocked at around 120 with a backfist strike,

I only guess nobody will hurt himself if puch the water the strongest he could

I get your point, but how do you get 2 * 9.8 * 10 equals 14? And even then, would it just be 10*9.8 - i.e. where's the 2 from?

calculactions are correct: 14 m/s (jump from 10 meters )

U^2 t V ^2=2as

u - initial velocity
v - final velocity
a- acceleration
s- displacement ( our 10 meters )

How are you going to coordinate your punch to be at exactly the right time, or are you going to punch repeatedly as you hit the water? Even then...

In reality, all you would be doing is extending your arm with a closed fist.
