Many of us have made suggestions about GPSTC. Should be no problem with that and of course no problem if it stays the same. If you spark an idea that inspires the hardworking crew behind it to do even more work, well good onya. It's run by volunteers, it's free to enter and it's already a brilliant success in the current format.
But nothing wrong with coaxing an existing system to do a bonus job. Why not form a couple of new teams. The Under 14 Allstars, the Under 15 Allstars etc. World wide membership in each team. (Can you co-join teams? Double post? Retaining membership of your local team under a slightly modified monica?)
At a glance of the team stats you could compare pbs, jelly bean tallys etc. No extra programming required for the GPSTC organisers.
OK, so it's time for me to fess up, I'm also on "the committee", and I was for a change to the age divisions, both young and old.
But as with all committees, there are several varying opinions about most things, and no real agreement about the nature of changes to the age divisions, or if we even wanted changes could be reached, let alone Neb's time to implement them.
Neb's idea of the age filters was a compromise all of us could agree on, so maybe it's not the ideal solution to everybody, but it's all that's going to happen on this matter.
As Sausage says, it's only an advisory committee, we have no power!
It's probably not the ideal way to run anything, but the GTC is very unique, I'm not sure there's anything else quite like it.
So I'm afraid you all have to put up with us until something better comes along.
The GTC belongs to Nebs and Hardie, they've created it with expert consultation on this forum, and made it free for all to use.
Anybody is free to make suggestion on improvements, but if everybody's request was granted, the whole thing would probably change out of all recognition, most likely for the worse.
by posting you just 'did' buy into this. You also asked questions which in turn 'buy' into this. You can't have your cake and eat it too Keef, sorry.
Neither of my kids sail, but if they did, I would be horrified at them and embarrassed at myself if we were carrying on like this.
No wonder Hardy wanted out if this was the kind of attitude he got.
Maybe we should have an abdication and all the current committee members resign and let the vocal minority run things.
ok Andrew it looks like i'm in, you know, tell me if im wrong but your post was a bit hostile which caught me by surprise because you don't come across that way on the water
obviously you haven't met arkim ,too arkim windsurfing isn't about me its about the kids and im not talking about his kid's , just for the record Alex is sponsored and I imagine he gets a good discount on gear(and doesn't need learning gear)
last year Akim brought some kids learning gear, boards ,sails and booms(EBAY,SEABREEZE) for the purpose of any kid that wanted to come along to use , I have seen him on numerous occasions rigging 4 rigs for the kids after school,then taking videos and pics and teaching the kids without getting wet or sailing himself
he put a post up on these forums and invited kids to come down to sanctuary point , we had a few families from Sydney turn up ,which he put a lot of time into and gained a couple of lifetime friends
there was also one guy who invited him up to hawksnest to teach his kids while he went formula racing![]()
ok so so far we have had a lot of red thumbs for arkim, I imagine it's from the majority of guys who think quality time is me time , and after saying that there hasn't been one person replying to these posts that have children sailing
I did a count and there are 80 kids world wide posting on the gps teamchallenge under 12 to 17 years old , so I take it that the majority of the windsurfing community don't have kids
you know its sad to see so many selfish people out there ,
you know a few years back when I first got into windsurfing it was a family outing and we were there for the day with esky and picnic rug , most of the time the kids were paddling or jumping of the boards rather than sailing , it was a great outing and the people were friendly, a lot more than I can say for some people who post on these forums
here's a bit of food for thought , the act gustbusters has a champ in the making and I hope too see him down our way to meet akim elli ,anna and his mentor alex
www.gpsteamchallenge.com.au/sailor/view/4281 SAMSON CHAMPNESS , I haven't meet Sam but I imagine hes the son of peter, www.gpsteamchallenge.com.au/sailor/view/3984 I am a proud gustbuster to have a little kid like Samson choose our team rather than go with his dad , to me that shows a lot of balls for a little kid
as I said in my first post I have nothing to gain from this post because my kids have moved on , what I have gained is a true friend in akim and the same goes for Anna Alex and Elli , just ask them who there best friend is in the whole world and they'll say DAD ![]()

Good onya Keef, well said. Just goes to show. Akim getting red thumbed on the internet!! On a windsurfing forum of all places!! The internet really is an alternative Universe. Strewth is stranger than friction!
Couldn't agree more Ian, I just hate the red thumbs!
If you disagree with something, talk about it, then theres a chance of understanding each other.
Red thumbs don't help anything, just produce bad vibes.
Laurie please get rid of them.
Good onya Keef, well said. Just goes to show. Akim getting red thumbed on the internet!! On a windsurfing forum of all places!! The internet really is an alternative Universe. Strewth is stranger than friction!
yer especially when he's teaching kids to get into a dyeing sport, 80 kids from 0 to 17 world wide what's that tell you
, my bet is the red thumbers don't have any kids in there team
I do thank all that make the GPSTC work. It is a great thing.
My problem is that KA360 has been slammed by all on here as he brought the topic up a year ago......
..............Just the same every year when the topic is raised of what changes to people want to see in the GPSTC, I always put my 2 cents in and ask for a 500m division. Knowing that it will get shut down. But I am still entitled to say.
Chris,
Everyone is entitled to offer their critisism and ideas regarding the GPSTC. It is welcome and healthy for us (the whole GPS community, not just the almighty advisory panel) to debate the merits of such suggestions.
The current issue I have (me alone and not as the spokesperson for the GPSTC, which I am not as is nobody else barring Ben or Hardie the spokesperson for the GPSTC) is that with Akim's original and valid request, we as a group came to the consensus that the age filter would not only cater for him, but value add to the site's functions as a whole. It, as has been mentioned previously, was the most brilliant and simpliest of all the options put on the table (for the record I do not see the age filter as a compromise but a very clever resolution to a member's want). To then post a new thread after the issue had been resolved demanding what the GPSTC was doing about the Junior age divisions I took umbrage.
Also no one is questioning Akim's dedication to windsurfing and in particular the junior ranks of the GPSTC with all the effort he appears to go to in teaching and encouraging a large group of local kids. What I'm questioning is his apparent perception that the GPSTC owes him something and when he clicks his fingers we should all jump. There's no point in me replying to his comments regarding "personal attacks, innuendo and put-downs" or the fact he perceives my responses as the official line taken by the panel - they are mine and mine alone and I'm comfortable calling him out on this issue because if someone doesn't then petulant behaviour eventually gets rewarded.
Re: Here's an earlier response regarding the 500m category too. I still haven't found the original thread but believe me when I say the difficulties associated with programming this category is quite complicated....from my very limited knowledge of programming it's not so much from the actual gathering of the data but from the way the website is arranged that it would require a complete redesign of the entire website. This is not something we could expect Ben to undertake nor would we have the funds to commission someone to undertake.
Changing subject slightly, but is there any reason why there is not a 500m category ?.
Simon,
I recall this was discussed previously and will try to hunt down the thread. My recollection was any distance measurement from time based devices (GPS) comes with inaccurracy - that's why we have time based categories i.e. 2sec 10sec 1hour. (Your Nm speed is never exactly 1852m either). Also I think adding an extra category to the data base that Nebs programmed comes with added complication (table formats etc). I personally can't think of an existing category that could be eliminated for a 500m category.
hey, thanks for replying sic em, your thoughtful and civil reply was a nice change, thank you,
the "its just for fun" has been a steady line used by nebs, hardie and the committee everytime someone has a suggestion, in my opinion, the whole its just for fun is just being dismissive of peoples efforts, why even have a measuring device then? why strive to do better? why dont WE scrap the alpha for a "who giggled the most while sailing" category?
What about the national gps free race, is the winner the one who smiles the most?
yes , its fun, and there is a unity between team members, but its still a device most measure their ability by, just the fact that there is now a national gps free race should be evidence enough of where gps sailing is heading, a little more note worthy than, "just for fun",,,,,,,,and dont get me started on how little a thought went into the location off the national gps, it does suggest a lack of understanding about gps sailing by the planners.
as for this continual bull crap that the gpstc is hardies or nebs, they implemented an idea, 1100 people are thankful, thats why we use it, thats why we live it
they handed over ownership of the idea when they allowed others to contribute, the gpstc is mine, and anyone else who lives it, and loves it,
sorry to say, but all Nebs and Co. own is a website,
if they disagree, they could take it away, whatever, another website will pop up as there is a market for it,
again, I'm thankful, thats why i use it, and love it,
whether you disagree, or dont like me, doesn't change the fact that I've been a committed windsurfer, passionate gps sailor, long time member of the gpstc, and should be able to reflect, and suggest on the gpstc anyway I like, as should any committed gps sailor, without being berated if it doesn't align with nebs, hardies or the committees vision,,,,,,,,,,,,,,,enjoy,,,,,,,,,,,,,,,,,wusses!![]()

"Umbrage",, oh, and 'petulant behaviour"
Ha, I tell ya man, this whole committee thing has gone to your head, your starting to sound real regal,
"Real Fricken Regal", you sound like Joffery off Game of Thrones![]()
You should try reading a book one day Milsy - you never know you may just enjoy it ![]()
"Nebs and Co"... I wish! ![]()
Milsy is right, the ownership of the site pretty much belongs to the people. It's a lot more of a democracy than perhaps has been written about on here. If you feel strongly about it, then please put your hand up to join the committee! I certainly won't stop you.
Sites like this thrive on suggestions and energy from the people who are interested in it. People also tend to drift into and out of communities like ours, people get burnt out, others are always just finding out about it, so it's always a good idea to welcome new people into the fold.
Please keep suggestions like this coming. Discussion promotes improvement, and I'm sure that everyone responsible for the GTC agrees that we're always open to new ideas. If something is easy for me to implement, and there's a clear benefit to the site, then it will be implemented, it's as simple as that.
Milsy is right,
What did you say? Sorry, I couldn't hear you,
could you please read it out loud, sausage![]()

brian i'm not sure if you read my post about the fact that arkim doesn't want any changes
Brian i'm very surprised again with your post for continuing to be so hostile and negative towards arkim, I have horrid visions with you and rexy having a conversation about this matter
i'm not sure if you read my post, arkim doesn't want any changes to individually suit himself , what he wants is to keep these kids INTERESTED
if you have any kids of your own you will notice kids bail out when the going gets tough, what he's doing is making suggestions and as giving the gps committee some feed back about what he is getting from the kids,
your self and rexy your blinkers are on (tunnel vision) here we have the 3 monkeys hear nothing see nothing and arkim say nothing
arkim sit back and enjoy the ride were in control
i',m not sure if anyone else sees it my way , both of you guys need to chill out , Brian I have met you and you came across as a decent guy, all of your posts have humor and I enjoy reading , are you ok I hope this matter is sorted and both of you guys get back to the nice guys I remember![]()

I personally can't think of an existing category that could be eliminated for a 500m category.
Hey Snags,
The main reason that I can recall for not having a 500m division is people say that it takes about 10sec to do 500m at 40kts. Therefore this is the 500m. Plus the GPS tracks at 2 sec intervals which would make it hard to accurately work out the speed.
Either way, I am still going to be on the GPSTC and I will enjoy what ever categories there are.
Interesting reading guys.
I have a couple of nippers almost 3 and 6 and so easing them into boardsports gently, so my short term intent is not for them though I'm certainly keen to see some standard age divisions applied by AWA across the board, eventually. I believe kids do need to be able to work towards State and National milestones and I envisage Jrs being 12 and under and over 12's(to 18) and at the older end of the scale 17-18's cn opt to progress to Open division, though they would forfeit their Jr ranking(or something similarly uncomplicated). Initially young girls would compete with the boys and then in the older division they as young women would be rewarded/awarded as Girls or Jr Women or whatever the International Standard is or will be. I believe all divisions should be shaping or feeding towards International and Olympic divisions.
I can't really comment technically on the GTC setup but from my reading, the system as it stands is great. I also hear KA360's argument loud and clear and I am supportive of his philosophy.
Just a thought - would it be possible for GTC Jr rankings be collated by a GTC Committee delegate(or Kids Rep) with a more detailed age divisions on a monthly basis, and published for kids ease of access and motivation as per KA360's vision?
Yours sincerely, tugging the tigers tail, as usual,
Adam ![]()

he put a post up on these forums and invited kids to come down to sanctuary point , we had a few families from Sydney turn up ,which he put a lot of time into and gained a couple of lifetime friends

Ok, Keef, I have met Akim and I have many times watched him from afar at both Primbee and the odd time he has come up to Kyeemagh. I am not, nor for that matter anyone, questioning his passion for his kids or the other numerous other kids he teaches. I truly admire that.
My issue is that the changes he is asking for were debated and decided as being too complex and hard to achieve without considerable effort. It was therefore decided to introduce the age filters which in almost everyone else's opinions were deemed to be a great and easy addition to the site and pretty much catered for what he was trying to achieve anyway.
I invite Akim to voice to everyone here in this forum just what he is hoping to achieve and gain from the changes he would like implemented. If as he says he fears the kids are losing interest because they aren't topping or near the top of the rankings then don't you think that is a fundamental issue with what he is teaching the kids about the sport?
All this diatribe has taught me is that I think I will no longer post on the GPSTC. I am obviously never going to top my age group so I may as well give up. Because apparently that's what it's about isn't it? Winning...???
I am so done with this.
brian i'm not sure if you read my post about the fact that arkim doesn't want any changes

You do see what I did there don't you. Why the hell would I need to have a conversation with Andrew - it's all here on this thread in black and white.
I'm good too and I see myself as fairly decent happy go lucky guy but somewhat one who wears my heart on my sleeve and don't usually pussyfoot around issues (just like Milsy, who's always right as Nebs said
) I can be hot headed and boy when I see sulky behaviour in any of my 4 kids they quickly know about it. Life isn't fair, get over it.

If only they would!!!
If a junior or anyone for that fact has to wear a gps to enjoy windsurfing, then they aren’t really enjoying the sport.. put the gps away and just got out there and enjoy sailing. Sail and go on trips with your mates and enjoy the sport for what it is and make life long memories.
I think people get to tied up in there gps and numbers!
Just to correct the record........
.............. it takes approximately 20 seconds to go 500m at around 45 knots. That means 10 seconds is about 250m at around 45 knots.
Apart from those already mentioned, there are other reasons 10 seconds was chosen as the original GPS time period standard by the GPS-SpeedSurfing founders, including a deliberate choice to differentiate from the WSSRC distance records. Numerous reasons for that decision too, which IMHO, it's not worth thrashing through again now, if only because it is history, and it is with us to stay.
One of the most relevant and strongest reasons for the 10 seconds is that there are far more places to be found in the world where reasonably flattish water can be found to go flat stick for 10 seconds than places to do it for 20 seconds! The reasons that is good are self evident. Also, if you are really keen on the 500m distance you can still post it in, and see your rankings and progress in, the individual rankings in GPS-SpeedSurfing.
By the way: It's great to see the passion for our sport and GPSTC expressed in this thread. Hopefully we can all get some good winds to indulge that passion on the water soon! ![]()

Wasn't time based records "easier" for GPS units as measuring distance precisely could be an issue?
Wasn't time based records "easier" for GPS units as measuring distance precisely could be an issue?
Yes, but I thought that had already been mentioned. Anyhow, to elaborate: the Garmin trackpoint GPS devices we used originally had to be set to sample every 2 seconds. Even then, as we found out later, the accuracy was very unreliable, but if you tried to interpolate between trackpoints to get speeds for a set distance, eg. 500m, it was even worse!
The accuracy of the devices we use is vastly better now but most are still limited to 1hz so there are still issues with trying to get reliable accurate speeds for a set distance like 500m. Experiments with 10hz units run down the WSSRC 500m timed course at Luderitz have shown very close correlation to the WSSRC timing gear, but still need to use interpolation between speed data points. My take on those experiments was that the 10hz gps error margin was getting very close to that of the fixed timing gates, but it still needed a small correction/deduction to be 99.9% certain you had gone at least the speed claimed.
The further you go, the less the potential influence of interpolation error, which is one reason why the NM is pretty reliable using interpolation, or even the nearest second over the NM.
By the way, it is interesting to study your 10 second PB's compared with you 250m PB's in GPS-SS. They are very close at around 45 knots. ![]()
