Some times ago I proposed interesting new competition. Jibe Master.





Rules are very simple

GM = 1 hour speed x amount of gybes

Here is my entry for today sailing as example

GM = 15,71 knots x 52 = 816.92

So if you bored one day try to make as many jibes in one hour and post your results here ....

How do you count the jibes? In GPSResults they would be listed by speed order... Can we make it 1/2 hour ? it's hard to keep going for 1 hour unless conditions are favorable like steady winds and flattish water. Also quite a few people just post through KA72 and don't have gps software. And finally you could think of some way to weight the actual speed of the jibes...

OK that's how I've done it:
- In GPSResults set timelimits to your best hour
- Select Alpha 500, then increase the number of rows to be visible
- Scroll down and you'll get the number of jibes within 50m radius, so the wide ones after bearing away will be excluded.

For that session :

GM= 17.127 x 19 = 325.413

You have valid points to consider.
How I did calculations,
Using GPS Results I mark one best 1 HOUR - speed 15.71 knotts.
Then counted dips on the graph showing jibes.When competition get some footing / popularity some algorithm could be developed by Dylan / KA72 I hope :) to make automatic calculation a brisk.

Indeed to make competition fair some additional rules are needed. Because if we allow jibes constantly down wind , that will be completely unfair to those that keep sailing at same place as I did.

So something like 50- 100 m distance / max radius between first and last/or second last jibe should be considered.
This way entry point and exit must be very close.
We give the same chance to everybody, regardless of how much water down wind they may have.Indeed 30 minutes could be good to start with and easy to commit yourself.

GM30 = 16.12 knotts x 27 gybes = 432.32













to calculate all best jibes i needed to move 30 min block a bit right ( few seconds) to catch last jibe too.

1st award in GM30 by 31st January 2017.

To encourage I will sponsor award to the best GM30.

I will send you to your address the box of the best beer of your choice





Start sailing mates and post your results here

The nice thing about the GPSTC was keeping things simple, this just complicates things, what's the point? All jibes are downwind, if you turn upwind it's called a tack!

There can not be anything simpler the GybeMaster. Just keep going and turning for 30 minutes. Gybes or tacks, as you like.
GybeMaster is just another idea to close the gap between GPS speed sailing and Slalom Racing.Just post your score and I promise to send you beer to US is you win !!

24.7 x 43 = 1062.1.......

21.56 x 35 = 754.6

I posted one a year or two back that was at low to mid 20's and 50 or 51 Gybes. I'll have to have a look back for it. :-)

What I lean't from that is that you only have to drop one Gybe and it sends your average speed into the gutter.

That is way it is called Gybe Master on my graph I could see I dropped 4 of 52. So there is big room for improvements for me.

24.7 x 43 = 1062.1.......

Nice turns! The minimum speed of 11.6 knots, averaged over all jibes in this hour, is better than what I typically get in my best jibes (usually below 11 knots). Great to see what can be done. I'll have to work on my jibes a bit more...

Thanks Boardsurfr
Im not much of a windsurfer but i always enjoy the hr pursuit, it just sit well with what i think is sailing well
Making your turns and always plaining
I decided i need to improve the hr by not necessarily going faster but going faster in the slow bits, gype exits and upwind......
Before i was lazy on the regather, now i really enjoy trying to work harder on the regather and work harder on still driving the board with good bag leg pressure on the exit.....still a long way to go.....
Its been going well, i usually just ride my 113l falcon and this summer has been going great with heaps of 24 plus hrs and 25plus alphas on my tank...
What i see is people enjoying the entry to the gype too much, not really giving themselves a chance to be ready for a better timed regather and in a position to be driving the board on the regather with good balance and footwork......
We have a great environment where we sail, with some of Australias best showing you whats possible and then a heap of guys like me trying hard to challenge ourselves to get to that level....from along way back
Unlike you, i never analyze the data, my friend put this data up, all i ever think about is the sailing and how to do that better....
Good luck in 2017 Boardsurfr and thanks for your kind comment
The thought of Macro having to maybe buy me a carton is delicious. ....ill drink it on my houseboat!!!!!

#15 in the 1h rankings for 2016 .. I would call that "much of a windsurfer"@ The only chance I ever have to get a decent ranking is by sailing much longer than anyone else. I'm really glad there is a distance category .

Enjoying the jibe entry too much is definitely one of the most common jibe problems, and tends to persist once the jibes are dry. I'm definitely guilty here - it's too much fun to carve at full speed! Well, something to work on in 2017.

Just out of curiosity - do you usually step jibe (step as you open the sail, then flip right away), or do you flip the sail first and then step?

I step before the flip. ....over the yrs its got better
I used to put front foot in front of front strap, slowing things down to much
Now i basically step into other front strap
For me, high boom, skinny legs and fairly upright, it was about getting in a good position to be balanced and giving yourself the opportunity to feed down to the board with that good balance, now being able to regather a more powered up sail for better exit. ...
My gypes arent fancy. ....about 6yrs of just trying to improve, identify whats shiz and improve it
I learn a lot about my errors by watching better sailors and trying to understand what there doing.....
If you feel your coming in to hard and thats effecting your build up towards the exit, then just come in a bit wider,,allowing for a little more time to regather the sail earlier and be in a good position to be balanced and to be able to feed down to the board to accelerate
There is a happy medium, we do about 100 plaining gypes each sess, so not every gype can be your best, plus its tiring, just go hard for that first hr while the hands are still fresh and really challenge yourself to find one of the billion subtle skills that make up a great gype and just work on it......
I can see you posting some monster alphas this year!!!!

Look anything like this JM?

.be

Ha.....i only posted that because my friend Norm enjoys making movies
That day was super light, about 0 to 12kts, a 7.9 on my tank
I never got my back foot in strap, but Norm wanted to do it and i was happy to be part of it
He likes putting cameras everywhere on your sail and he sails out to the bank with a tripod strapped on his board and then he sets it all up
We are hoping to get some good footage in stronger winds this year
I've done 24 plus hrs and alphas with the 7.9 but its not really great, i much prefer the 7.1 in about 10 to 25 kt on the tank or the 99l,
The sess i posted for the GM was 7 1 on tank
And i had about 5 sessions with that sorta data in December, 24 plus hrs and 25 alphas
Just flat water sailing in a patchy 10 to 20kt
Budgy is a shortish run, in that direction, but flat turns, the question is if you'll get wind as its rarely great coverage over the full circiut in that direction
And there is always alot of other sailors to consider as well when trying to string an hr together at Budgy
You dont always get to turn hard if theres sailors on the same run inside you.....
My friends are much better sailors than me, Micky, Matty, Bruce, Tibor, the legend nsw sailor Larko, Jamie, the up and coming Troy but they never really care about the hr.......but if they did, they would kill me
If the ol Mike Thompson( NSW hr and distance legend) ever came back and got dialed into Budge, he would set the bank on fire with his hrs
I just hope to add about 2kts to the hr and alpha over the next couple of years so i can still be contributing to the team.........and for my own personal glory!!!
I dream of 27hr and alpha, personally that means more to me than breaking 40kts.....which is something awesome as well
Thanks to Norm for the video, all the Budgy guys love it and really admire your skills ol uNORMal......
Gold.....it feels like im houseboating this speed channel thread......

Don't let the modesty fool you, Shelly1 is one of the best and most consistent gybers, alpha'ers and distancers going around.

21.34kts x 53 gybes= 1131.02

Fantastic results. At this moment it looks like I will be sending the best Australian beer to New Zealand

Bloody Kiwis, take all the jobs and now the beer also....

Great video!

Nice work Mike.
Looks like L Clearwater?

Yep, you must have one similar or better, I'm looking for yours at the mo.

It seems the key is to be on a small lake so the runs are short.
At last we've found a good point about Lake Clearwater's short runs!
Terry, your 24kt hour in the estuary, runs were 2km and so 24 gybes only. 24x24=576
Even B-Rad's 30.37kt hour at Lake George is only 31 gybes. 30.37x31= 941.47

Even B-Rad's 30.37kt hour at Lake George is only 31 gybes. 30.37x31= 941.47

It seems that the best tactics for GM could be increase in amount of gybes not pursuit for overall top 1 hour speed.

I am guessing that somebody could do even 70 or even 100 gybes in one hour. Then without falling and assuming the all are planing gybes result could be astronomical.
For example doing 100 gybes when still able to keep average speed above 20 ktn will come to 2,000 mark !!!I should think about some special award for first person beating 2,000 .

What about free GW60 for first beating 2,000

( beside standing order box of best beer to best result by the end of January) .

So there it is : FREE GPS GW60 for first 2,000 GybeMaster !


Hopefully that is not possible so I will save a lot of money

Speaking of rugby prowess







, here's the T shirt my Ozzie mates (1 ex Ireland) gave me for Christmas. I only wear it working in my shed, wouldn't dare anywhere else.

I've found an even better run.
This is my mate Terry A whose data I store for him.
This guy is a good sailor, very good gyber and rarely makes mistakes.
This is a 30 minute clip (is t



hat ok?) because he only sailed for 50 minutes total.
30 minutes, 20.16kt average, 31 gybes = 624.96 x 2 = 1249.92 hour
On the same lake, short very runs.
Plus......he's an Aussie now !

<div>Here's an improvement. This guy is young and fit and fast and he really can gybe.
He was training up for NZ Slalom nationals in Dunedin in 3 weeks time.
This was in rough water and gusty wind.
2016 Carbon Art 87 Slalom, Maui TR9 6.3, Vector Rocket 32 fin.
30 minutes, 20.95kt average and 31 gybes = 649 x 2 = 1298 score for an hour.
He came off on one gybe and stood about talking for a minute.

<div>Even better as an example of possibility is the set of gybe runs he did earlier in his session.

<div>These runs were only 250-270 meters long and he did

<div>7 gybes in 3.0 minutes at an average speed of 19.1kts

<div>equals 140 gybes in an hour at 19 kts =2660 score

<div>2000 score = prize........ and the beer.
That will be a good test of fitness, to see if he can do that for an hour, better than any gym session.

<div>Earlier in the session his run for a full hour matched almost exactly Terry's entry so if he can do that with rough water he will smoke it in the flat.

If we get any!

Good work Kiwis So theoretically at least 2,000 mark is possible in full one hour.
Remember , my offer stand for brand new GW60 to the first that pass 2,000.
But 3 min sprint vs 60 min marathon mean real commitment, stamina and master skills .

Looks like we have a winner.Who says Beer can't fly ? Can and will. This time to Kiwiland, Congratulation
