It will be interesting to learn what technique could be effective for slowing down when running high speeds. How sailors stop at L?deritz - taking into account very limited space? How to stop in emergency while sailing? For our GC condition the reason could be speed boat appearing from nothing just in front of you,
but there is many other occasion for planned and less planned hard braking.Even the last resort, like jumping in the water need some knowledge ,how to do this safely for you and gear.


yep , this is example of what I am not asking exactly...something more lively rather..

I could already imagine too funny competitions here:
Rules:
1.Our speed sailors need to reach high speed and start braking at given stationery markers/ buoys.
2. The shorter the distance for marker to the top stop position - the better.
3.Competition results are calculated by dividing speed square , by stopping distance
example :
30 ktn x 30 ktn / 5 meters = 180 point
35ktn x35ktn / 10 m= 122.
36x36 / 7 = 185

competition could be divided into two categories: a) limited path width to stop- require in line stopping
b) unlimited sideways- allow for nice lay down gybe

Dump sail, carve upwind, skip twice.

I found a new way of stopping when I first jumped on a skinny board after months of just sailing the ultrasonic. It goes like this, go in for a flat out gybe, take back foot out of strap and put it where the leeward rail would be if you were on the ultrasonic, foot hits water and you stop really quick. Sometimes your kit even stops as well. Weeks later I still sometimes use this technique.

I did this at Green Island last year, in front of a group of Chinese tourists who were busy taking a thousand photo's at a distance of 20 ft . All I saw when I finally worked out that I hadn't killed myself, was a lot of blokes pointing (at me) and respective partners with hands over mouths laughing their heads off. I just went with it

When you go for advanced motocykle raiding training and tests - THE BRAKING- will have big part of that. I can not recall a single video , or instruction, discussion about proper , effective stopping on windsurfing board.
We know, everybody do so somehow eventually.
But there isn't any common knowledge about technique and style.
Like a gybe for example,.
You could exactly describe step by step , what to do with feet, sail , board.
The same with free style.Combination of 360 flips must be precise and repetable.
Stopping so far is random discipline, without any style, only personalized flavor.

Possibly because nobody of us think about this when arrive to the beach, after sailing.
Why not to finish in style ? Like olympic gymnastic landing on two feets, hands up, and smiling.

So next time on the water, think about that.

How to arrive to the beach bank with speed , slow energetically in style and make crowd cheering, mates splashed with water!!

Wtf????
Everybody have a video this days,.Lets do following experiment:

You will accelerate to 30 ktn, then attempt to immediately stop ASAP.Ask you mate to make a video, showing us anything else that you have been ride over by the train.

you are in control, ABS is engaged and fine on wet surface....
good lucky
Ok, my fault, I should use scientific terminology here

The topic is about CD as opposite to UD
( Controlled Deceleration vs. Uncontrolled Disintegration )

In the place like GC where speed boats pop up from vacuum space everywhere ( according to QM) , the first five minutes of our REACTION TIME takes to recall if there is any method to stop this thing ( your board ) from going.

stop thinking macro
just get out and sail.........

I think the quickest I've stopped at speed is ventilating the fin, tripping over a chop and catapulting into the sail, probably went for 30+ to 0 in 5meters. But I'm not going to do that on purpose! I tried a full on upwind carve at sandy point once, right in front of that nice lady photographer, didn't sink the rail enough, spun out landed flat on my back, it was still quite effective as a stopping technique, but didn't have the intended visual impact.
The sail acts as a great water brake, has anybody tried, sheeting out and jumping off windward side, sinking the mast as you go. Could work too well, and you may not be able to stop yourself having an unwelcome impact with mast/boom.

I tested today concept of Rapid Deceleration in the place you think you know well.From 30 ktn to 0 in less then a second. Scientific investigation a moment later found that water was 10 cm deep. If that was a 5 cm more or fin other then pointer I may slide to the deeper part in next second.
Apparently the weaker part in the chain happen to be top sail batten, the took all this force and broke in half.
The rest remained unharmed.
I am a little bit disappointed because once at home and trying to compute rate of deceleration; nothing happen! GPS Results doesn't accept Motion GPS files. What a shame ! Such sacrifice and wasted !

GPS-Results DOES calculate Motion .oao file. Download a newer version. (V6.71 onwards)

yes. My fastest stops have often involved a fair bit of breaking!

The one time I 'spun out' in the Luderitz channel, I was able to drag my back with the board sliding sideways for far enough so that when the rig finally dug in, I had slowed down enough not to break anything, and more importantly, I stayed in the channel.

Stopping at the end of the Luderitz channel:- There are plenty of videos of guys doing it, but a spectacular 'laydown' is not really nessasary (however cool ). Turing downwind and sheeting completely out starts the slowdown. Sinking the tail contimues this and once down to lower speed turn upwind to stop at the bank. Only on one run did I bail out when the plan above didn't quite go to the script.

Stopping at the end of runs at Sandy Point when coditions are Epic, is similar, but the turn downwind is much less, and the urgency is also much lower.

In an emergency, the safety of person is paramount. Just let go and drop into the water. You will stop quick! If you can't unhook fast enough, sheet out and drop on you back. The rig will dig in and stop you VERY fast, but it might hurt a bit as you body impacts the rig.

Yep, Stopping at Sandy Point is Epic, when conditions are right. For you guys sailing there is bread and butter, but for visitor like me coming on really, really windy day it was complete surprise. Well overpowered on KA 5.0m, 71L25fin
-at the end of the run can't go up wind anymore , since sailing already few cm of the sand bank!
-depowering sail doesn't help also, board is still going like crazzy, even with me standing straight and flopping the sail free.
-gybing out into the chop is also not my first option !
-ducking into the water ? I may not catch my rig anymore- will fly to the other side of the river. everything around is flying already, including dunnes
I may hit my lifetime PB on this day at Sandy ,but since didn't have GPS - doesn't count.
But my advice stand.
If you visiting Sandy Point on windy day, better to ask locals how to stop at the end

I think you are missing the fact that at the end of an good Sandy Pt run, you are already very broad and the power in the sail is almost always not that high (unless it happens to conincide with a 50 kt gust ) You simply take the power off (carefully) and sheet out, turning slightly further away from the bank. That last part is often not even nessasary. Stand up on the board and completely sheet out. Keep in a slight crouch to absorb the chop with your legs, sink the tail to slow the board and turn into the bank to step off. That last bit is easy. The only dicy part is avoiding losing the fin as you back off.

But that is only one scenario. Every day is slightly different, but the basic proceedure is similar. Sometimes the wind is not really strong and not quite broad enough to get the best anle on the bank. So you bear away from the bank for a few seconds to get the max speed. In this situation, you simply back off and round up.

I have seen Vano' do a scorching 47 knot run fully 10 meters out from the bank in very 'rattly chop' I was fully expecting a massive crash at any moment! But he is Vano. He made it. . At then end he just had to round up into the bank and step off. Vano is Vano! though.

It's not that hard to just watch how others do it.

if you still fear stopping at the end of a run, you probably don't really want to go as fast as possible anyhow.

Watch Kato stopping ar Sandy Pt here from 40 second to 56 seconds.

And again after a stonking run between 2.00 and 3.06.




That was a very testing day and Kato made it look easier than it was.
gpsteamchallenge.com.au/sailor_session/show?date=2019-04-26&team=16

how long it takes to walk back?

I have an emergency stop I use. It works well although it could be risky.. I've never had any problems so far..
Let go of the sail and fall backwards still in the straps.. Your body acts as the anchor.. I use it when I'm doing a bearaway into shore and running out of room to stop..
I usually do it in deep water..

I can identify with the drowned cough at 1.39..

I never tire of watching Sues elegant dismounts whilst hurtling towards the shore

How is it on the ankles?

My first time at Sandy Point, stopping was the scariest part. It took me a while to get the hang of the bear away from the bank, open the rig, turn back towards the bank and sink the tail stopping technique. It's now second nature and I use it all the time when sailing behind the bank at Wello, Lota and Burrum Heads

Grat Video! That is what I am talkin about!
btw that bring my another idea/through

We know that for general public watchin windsurfing competitions on TV could be a little bit boring.
Imagine Olympics foil gracefully floating at 30 knots, passed by flying near by cormorants' and pelicans,.
Beautiful view that could compete with National Geographic channel of life streaming plant growing in real time.

Second in the row is jumping and landing on the head free style completion.

Not my favorite as I prefer rather to avoid hard landings and sinking in middle of our speed chanel. May annoy someone.

But there is another competition going in semi athletics rather discipline then pure sailing.
Our athletes windsurfers , crank and rev their wind motors , speed up to to +30 ktn and more then stop suddenly ( as opposite to " long distance sand jumpers". The shortest coming to stop line and most energetic wins!
score= speed x speed/stopping distance

Revenue from ads is growing, profit shared between commercial tv and athletes windsurfers.

One may point that 30 ktn is not guarantied on everyday Olympics.
There come solution,.
We could already ventilate sweeming pool to make indoor windsurfing possible .

Why not to create olympic speed run made of series ventilators setup outside this time, on the smal lake kayakers use?

All we need is row of 10 -20 ventilators along the run.Then most of windsurfing competition could be carried everywhere!

And when you're doing these sudden stops just be careful how you get off. This was only an 8kt step off and after years of getting off way faster at the sand bar.

So far I've never had an issue and my left one has a plate and 8 screws one side and a screw the other..
It could be because I do rotation and other maintenance chiro exercises on it daily and it's pretty flexible.. ?
Yes Andrew you loved the rail up / catapult one in particular..
I found the going to gybe a narrow speedboard and stepping off the side method nastier..

Macro I'm suprised you're talking about sudden stops etc done safely I certainly remember an incident at the train at Southport around 2006 - 2007 where a certain sailor decided to come into the shore at speed and colliding into other sailors who were stationary waiting to launch.

Let's just say that sailor was close to being skull dragged out of the water by other sailors and knuckled, only to be intervened by a local sailor and stopped it going any further while the offending sailor was mindless to what was about to happen to him and didn't give a rat's about what he had just done.

Then the incident involving Linda who was hit by a jet ski in 2011, be a bit more thoughtful how you address this subject of Stopping in GC conditions Hey?

WOW

You poor clueless soul. Doesn't ring a bell for you Hey!

When you engineered/mastered how to stop for speed sailing safely, you should demo it at Burrum, Sandy Point, Lake George and Luderitz. I'm sure it will have everyone on the edge of their seats!

You may have some problems mate But it shouldn't be my problem too.. If you not interested in stopping technique and tips shared by the best here in business. skip the topic please.I am here to listen and learn more...anyway you are lucky that you are not sailing here on GC anymore ( if ever) with you negative attitude.I am the most peaceful person in whole world, But one day I did dare to make a comment to the house boat owner that just parked in the middle of our running strip. The guy immediately jumped into his dingy, run the outboard motor and run me over ( sailing on windsurfing board) .I learned hard lesson and keep mouth now shut , even thank anglers for fishing lines throwed at me while passing by. One wrong word and instead of fishing line, it will be stones landing on my sail .So when you arrive to GC sailors are polite, help full and smiling. We could not win with angry force against speed boats, jenisejski, houseboats , even crab pots.

Some memory loss there Macro over the years! Now theres a problem.

I could go on about 2 events/Incidents you were part of but you dont seem to remember and it directly relates to your subject.

or do you choose to forget what incidents you were involved in or clueless that you were involved.

I even recall at Burrum one year you failed to listen and learn. It only was spoken about recently.

but lets be positive,none of us are perfect, your trying to learn now.

I'll put it to rest now if you like Macro.

2006-7 I was living in Melbourne and sailing Rickets Points / Mentone mostly. Cant remember hurting anybody. You may confuse me with somebody...
1.Story
that remind me another guy here chasing windsurfers in the park with sharp knife. Guy was on drugs obviously, police called, not sure what exactly griviences the guy had to windsurfers. But he did remember some numer on the sail and have been looking for the number on the beach, to get the guy the stab. Whole twist in the story , the sail was resold recently to new owner unaware completely.
2.Story .
From Burrum I have only positive memories. One the best is from my first visit, while we all get to the Norhtern bank for sail. Then on way back,. wind died and my 81L board sink in the middle of channel. I was drifting hopelessly, exhausted with strong current. Fortunately barge was picking us one by one from the river. B ut somehow I still have difficulty to pop into barge. Then KATO jumped into water , and help me get inn. That is the gesture I remember and never forget ! I didn''t know even back then who KATO is , but since then he is my hero.
