Happy 5th Birthday GPS TC

TASSIEROCKS — Thu, 24 May 2012 19:12:59 +0800

I was curious and just discovered (from what I can tell anyway) that the GTC is 5 years old this May. From a total number of 58 sailors to now well over 1000 is a fabulous achievement for the guys who made it all happen (especially Nebs and Hardie) .

I've now been a GPS TC'er for about 3.5 years (joined around the beginning of 2009) and have meet some great people and very interesting characters . It has increased my love for the sport ten-fold and I hope to still be doing it when I'm as old as Firiebob .

From reading about Elmo's epic tales of woe to the big sessions at The Pit and Lake George, the long forgotten blow ups debating doppler postings versus trackpoints & Navis v Garmins, friendly inter-team and team rivalries, Bender's bruise, people stoked to get their first 30knots on the board, juniors coming of age and blowing the oldies out of the water, and the introduction of international teams to the fray, has been a really enjoyable ride down the speed run....

KA72

decrepit — Wed, 23 May 2012 20:43:59 +0800

Hi guys,
I normally use Gpsresults on its own but through a friend have just discovered the convenience of KA72 in working it all out and providing a google earth overlay...

My question is about alphas, When I upload a file to KA72 it seems to not take into account the 50m radious rule for alphas...

I have the alpha width on gpsresults set at 50m which when measuring tracks against google earth seems to work as it should. However when uploaded to ka72 I get lots of new alphas but they dont appear on gpsresults unless I turn the filter off.

EDIT: I have found on a site that KA72 only requires an alpha to be 100m long, On GPSTC it states an alpha is 500m long.. upon uploading form ka72 to gpstc does it only include alphas over 500m in length or should I be making that calculation manually through gpsresults?

any thoughts?

Fins for Isonics

shinobi — Wed, 23 May 2012 13:09:18 +0800

Gday Boys and Girls.

Ive got a 101 and a 76 isonic. I after some advice on what fins work best on these boards?

Id use a 7.6 and 6.6 on the 101 and 6.6 and 5.5 on the 86. Im a 100 plus kg and love to push on the fin. So something stiff and fast.

What do u guys reckon?

Been meaning to put this up for a while, this at the RSX Olympic class worlds this year in Cadiz Spain. This day it was considered unsafe to race so Mr Neil Pryde decided to put up 1000 USD for the fastest RSX sailor. GPS's where used, only a select few nutters went out. why? Because it was gusting over 50 knots and 9.5m2 sails and 50 knots do not useually mix :) enjoy

Fin recommendations for 122 Futura & 8.5m?

boardboy — Sun, 20 May 2012 18:11:25 +0800

Apologies for posting on the GPS & Speed thread but i figure most of you guys would have a big rig setup for the light wind days.

Im after fin recommendations (size and brand) for my 2011 122L Futura and cammed 8.4m North. This is my light wind setup, I would rarely sail this combo over 16kts, early planning is the priority preferably with a fin that is reluctant to spin out from my lack of skill. I weigh 80kgs.

Thanks

Sandy Point last weekend

TASSIEROCKS — Sat, 19 May 2012 19:26:05 +0800

Found an old bloke passed out behind the pub in Eden. He was wearing a Gath and with a Gopro on it. Anyone know who he belongs to?

Thought you Pit Crew boys might be interested.

Now what in the GPS world?

ratz — Mon, 14 May 2012 20:21:13 +0800

A while ago the question was raised whether the 30kt alpha or hour would go first.The Alpha went first and it looks like we will soon see the 30kt hour ( maybe even a team average>30kt hr)
What is the next huge milestone?

Simmer/Mistral

looks like Simmer is putting a bit of colour back into windsurfing

And someone has been able to get their hands on one of the new Mistral speed boards designed by Chris

Breaking the 30 knot barrier

paddymac — Sun, 13 May 2012 22:14:03 +0800

It seems a lot of us hover about just under 30 knots trying to make that breakthrough for quite sometime, then once past 30 they come along frequently. There must be some breakthrough in technique which allows a sailor to finally get past that 30 knot barrier.

Obviously you need enough wind, to bear away at the right angle, and flat water helps, but what else did you do differently to get past 30 knots?

gps speedo calibration

Mux — Thu, 10 May 2012 10:57:41 +0800

on the way back from cheesegraters, thought I'd test my new wagon's (2006 VZ commodore) speedo.

set the cruise control at 104km/hr on the speedo this is the result.

Unlike the Hyundai (speedo and odo read 3% high) the commodore odo is spot on.

Bottom sandwich is on, next step is the top sandwich.
Keef is working on the footstraps.

My big question is, will it get me to 70km/h before I'm 70?

Thanks everybody that helped with the tail width

Garmin GPS Question for the GPS Experts

GeoffS — Fri, 27 Apr 2012 20:11:29 +0800

I am having some issues with my Garmin Geko GPS and thought the collective knowledge may be able to help, and yes I know I should get a Navi but the purse stings are pulled excedingly tight.
The GPS performs great when I'm on my Formula board with no suspicious speeds or times. However once I am on my iSonic 125 I seem to be getting some strange results. I think the results relate not so much to the board but to my ability and the fact that on the iSonic I fall in a lot and on the Formula board I dont.
When I put my track into KA72 (thanks Dylan) and a strange result appears, one which I am sure is beyond my ability, I go to Realspeed and usually there is a red line that joins 2 points which I cant remove by using the 'Delete Invalid' command.
My real question is what is causing this? Can it be that the GPS loses signal when I am in the water and then takes some time to pick it up again, creating the illusion that I am a 'Gun' sailor?
Any other ideas welcome, with if possible a way...

Makani Speed Fin

mauiboy — Thu, 26 Apr 2012 21:21:05 +0800

I've see a few pics of the new Makani speed prototype, It's being tested now but I'm not sure when it's going into production. If it's like the rest of their fins It'll be awesome, Maybe a weed version as well.
