This my recent achievement.
From 27 knots to zero in less then second 
I am sure many of you could beat me with much better decelerations !
Your data are wrong - they show a positive acceleration of 1/2g as the speed drops from 27 to 0 in one time step.

That is not a competition I would be trying to win.
Interesting will be to see similar table from high speed crashes.
Definitely some sailors come into trouble well above 30 knots.
For me it was very soft landing as simply gust took my gears with me on top in the air and away, and I did land on the back in the water .
I guess catapult records must be much more terrifying.
I see your 27 and raise you 30. (Note the red line limping away slowly afterwards)

Gps showed 36.4 to stop with a trip for some stiches....
From one Ranga to another, it looks like an improvement in ya looks

We know they were sudden stops, and believe me when I say I know what it feels like, but unfortunately the GPS's were unable to record the actual deceleration. Notice that the m/s2 column is 'na'.
It's hard to run a competition without valid data! apart from 
Both sets of data in the above posts are invalid - note that the number of Sats is 0.
The GT31 can measure decelerations in excess of 0.5g, however, if it is not under water.
I have attached some valid icesailing data showing a spinout on shell ice and linear deceleration in excess of 0.5g.
How to stop gracefully

If all we're going on is statistics, then i reckon Muffin Man Pete takes the cake from a few years back with his stack at the PiT. Resulting in him wearing a full face hockey mask everytime he sails now!
All new mobile phones have now acceleration meter inbuilt.
But adding possibility of damage my newest Galaxy S6 to the cost of eventual gear trashed doesn't help much.
Anyway smartphones software loggers which transmit our GPS logs automatically and have proper accelerator may be in not distant future.
I just have a look at Android accelerometers apps for smartphones and they looks and works amazing . Precise 3 Dimensional axis graphs in real time.
Hopefully the scale of the mechanical device is outside the limits what we humans could handle.
Beware of blunt chest wall trauma leading to myocardial infarction.
So take care in your stacks. It is not just your head that needs protection.

Was that what happened to you recently Yoyo?
Here's a nice sudden stop......I was no longer on the board, bailed off as it went up the boat ramp. Hit the bottom hard (gravel) and even skinned my knuckles with this crash.

I totally agree!
I was looking for the 'after' photo to post, but I haven't found it yet!
Here's one from 35 knots to zero in 2-seconds!
And the resulting damage to a brand new sail ... (mast was still intact, but both boom arms bent)

Excellent deceleration at 1min37

Ouch! Was that the one where the unfortunate sailor broke his arm?
In this one the board stops a lot quicker than the sailor. He was still pretty shook up though! I think it was 42 knots to zero in a couple of seconds!

No, this one was Jacques Van der Hout eating it.
He doesn't do that very often, which is fortunate with the speed those guys go.
