Windsurfing activity

Hey wizards,

Sorry but my english is not so good.........

I'm not a programmer so my wish is to have a windsurfing activity, i know there are a lot of guy's searching for something like this!!
I tried to find a lot of info and data...

Session data
When calculating the session statistics it is important to comply to the following rules:
- One best per run
- Linear Speed. (Linear speed means that you calculate the speed over the exact positions a rider has sailed)
- No interpolation of distance speeds

GPS Track Setup: 0.5 or 1 Second
Interval: The interval is set to 0.5 or 1 Second (0.5 is the best and more accurate)

A session consists of (is it possible to see this on screen?) :
- Max GPS - Highest speed seen on the display of the GPS
- Max 2 sec speed - Gps Highest speed over 2 seconds
- Max Software - Software calculated highest speed
- 10 sec run - Software calculated average speed over 10 seconds (the AVG for the ranking is calculated over the 5x 10 sec runs)
- 100m - Software calculated average speed over ‘one’ run of minimal 100 meters
- 250m - Software calculated average speed over ‘one’ run of minimal 250 meters
- 500m - Software calculated average speed over ‘one’ run of minimal 500 meters
- 1852m - Software calculated average speed over ‘one’ run of minimal 1852 meters (Nautical Mile), turn allowed*
- Alpha racing – Software calculated speed over ‘one’ run of 500 meters with a gybe and a proximity at the startpoint of 50 meters.
- 3600s - Software calculated average speed over 3600 seconds
- Distance - Distance sailed during a session
- And hart reate, calories, Hs-Zone etc

Please send the data via the automatic upload function in the software. This prevents making mistakes. Do not forget to fill in the Max GPS as this is used by the Timekeepers to check against the software calculated speeds.

A run is when you sail in one direction and per run you can score only one speed. A new run begins after a turn (gybe or tack) or when you have stopped. The only exceptions are the Nautical Mile and one Hour speeds where turns are allowed.

A valid run has no spikes and no strange accelerations. If a spike occurs at the end of a run (because of a crash) the spike may be deleted and the run can count as a valid run.

For Doppler devices in the GPS analysis software the following settings are necessary:
- max. Accel. [3 m/s²]
- max. HDoP (5)
- min. Sats (5)

Track format
A track must be delivered at the discretion of the RTK in the next name format: YYYYMMDD Rider Location.gpx or the Navi generated filename is also ok. Please make sure you have your Username set correctly in the Navi.

When you have deleted spikes in a copy of the original file than add ‘cleaned’ to the file name. (example: 061205 John Doe The Spot Cleaned.gpx).

Only tracks in GPX or SBN/SBP format with minimum of 6 digits precision are allowed.

Extra info (i know that it is for Suunto but maybe it helps) :

5X10S MAX AVG
WINDSURFEN/SURFEN, TRAINING
Calculates the 5x10sec MAX AVG like the GT-31 does. There is only one best 10sec average per run. A run is finished if either the speed drops below 8 knots or the GPS heading turns more than 70 degrees within 4 seconds. It also beeps whenever the 10s MAX improves. When the speed is over 8 knots, then it shows the current speed in knots, otherwise it alternates between 2s MAX, 10s MAX and 5x10s MAX AVG in a 3 second interval. Ambit (size 100%), Ambit2 S (size 48%), Ambit2 (size 48%).

I hope I have given you enough information for making this activity, I really hope that someone want to create this!

Speed calculation Accuracy

Nathan, this is really good progress with the app for the Forerunner 920XT and is making this a good contender for replacement to the GT31, and a useful watch as well.

One of the key reasons the GT31 was so successful was the calculation of Speed Dilution of Precision (SDoP) which was a special calculation not usually included in GPS logs, because it required extra output from the GPS chipset to calculate. It would be good to include a speed accuracy measure if possible.

Also I do prefer the look of the VivoActive. Any possibility of 1s logging for that?

Finally the app is out!!! Check: https://apps.garmin.com/nl-NL/apps/b820a772-e335-406a-85b7-2ac6a0e5b61a

Beschrijving

This datafield has been made for Windsurfing or Kitesurfing. It displays the best 2s, 10s and 5x10s. It also shows all 5 best 10s individually. There can be only one 10s per run/leg. One run ends after a turn or when the speed falls below 8 knots. The speeds are show in knots.

On the Forerunner 920XT it is suggested to use a 1-field layout. Then it alternates between two screens. One that shows 2s, 10s and 5x10s and another one that shows all 5 10s individually. The colors indicate how close they are to each other. The greener the bars are, the closer they are to each other and the better. That way it is easy to see if there are for example 2 bad ones, which need to be improved.

If the speed goes over 8.5 knots (30.6 km/h), then the datafield shows the current speed. After a run is finished, which is usually after a turn, then it shows the fastest 10s of that last run. The labels are either 10s_1, 10s_2, 10s_3, 10s_4 or 10s_5 if the 5x10s has been improved. If the 5x10s has not been improved, then it shows Last 10s.

If another layout than the 1-field layout is used or then the datafield cycles through the 2s, 10s_1, 10s_2, 10s_3, 10s_4, 10s_5 and 5x10s numbers.

Is it possible to get this app for the Fenix 3 as well?

I found the other thread in the showcase section: https://forums.garmin.com/showthread.php?245262-Datafield-Windsurfing-Kitesurfing

And since last week the latest version that supports also Fenix3 is also in the Connect IQ store:

Trying to use datafield

Is there a tutorial how to use windsurfing datafield on a vivoactive? I know how to load applications but cannot seem to get datafield to work unless I'm missing the concept of how they work. Same issue with Elevation datafield.

Opperhoofd_101 over 9 years ago

It's a datafield, not an application.

You have to use an existing activity, cycling for example, and modify data screens. Pick one of the screens and change a datafield to the windsurfing datafield. After that, start the activity and check your datafield while windsurfing. That's it.

It works on the vivoactive which is very nice from the developer. If you really want to enjoy this datafield you need the 920XT at this time.
I've read an application is on the wishlist of the developer. In that case it's the same as the 920XT except for data recording. Data recording on the vivoactive is useless for gps-speedsurfing due to lack of a 1 second interval mode for recording.

Fenix3

I have the datafield wind/kitesurfing on my fenix3 watch.
While surfing i see my runs: best 2 sec., best 10 sec., 5xbest 10 sec and average of the 5 best 10 sec.
Bit where can i find these results after i save them?
And how can i upload them to gps speedsurfing?

Opperhoofd_101 over 8 years ago

It's a datafield. It's temporarily and has the lifetime of your recording session.

Of course all data is saved in the activities folder (on your device) as a fit file. Using autosync with Garmin Connect you can go to your activity (with the web interface, not the app) and export it in gpx format. That file can be used in gps action replay and gps results.

other watches

Dear Fin151,

please write if the windsurfing datafield is avialable for FR620 or FR230?
As I know on speed competitions the every second recording is a must. And vivoactive have just smart recording.
Thanks, Peter
