2015 AWSA TECH
CONTROLLER
MAINTENANCE CLINIC
GENERAL SECTION
The purpose is to provide a few reminders of the TC
requirements and to provide an electronic clinic for TC
Maintenance Only (which is required every 4 yrs).
This Electronic Clinic is broken down into 5 modules.
• General (for all events)
Responsibility, Tournament Class, TC Report, Nat’l Record, Survey,
TC Maint, Equip
•

•
Slalom
Jump
Tricks
Survey
2015 Rule Changes
Because we can not cover all the requirements in this
clinic/presentation, please review the AWSA, & IWWF Rule book
and the Technical Controller Handbook (2007).
Technical Controller (TC) responsibility:
Ensure that the site (course/setup) is in accordance with the
IWWF/AWSA Rules. If there’s a question/clarification of the
tolerance or setup, contact the AWSA TC Chairman(s).
Ensure that everyone has a fair opportunity to compete,
and particularly to ensure that all standards at the event
are equal to any other tournament.
Remember to ask:
“Is this fair for the skier?”
And
“Is this fair for ALL skiers world wide?
Tolerance are for human and mechanical error only. They are
NOT to be used in helping skiers performance. It is your
responsibility to attempt to be as close as possible to the
actual specification. The official measurements are in Metric.
Ref: IWWF 1.11
TC is the independent verifier/ inspector for the site; verifying
that it meets all IWWF/AWSA specifications. It is his/her
credibility that is on the line, verifying that everything is
correct/functional and that the tour is being held to the
HIGHEST STANDARD. We can not afford to allow our RECORD
tournaments to be degraded.
In additional, in case of a law suit, it may be you (who certified
the setup) that will be questioned.
A lot of site owners/partners have become TC over the years.
It would be good practice to use an outside TC periodically to
provide additional verification. There’re too many record
tournaments and not enough TCs for it to be a requirement.
The site owner/TC should use good practices to prevent any
issues/questions or an implied conflict of interest.
Tournament Class
Class R – For setting World Record Only.
Class L – World Ranking List
Class E - For setting Nat’l Records.
Class C - For AWSA Ranking and qualification only.
Type of Competition:
• International Tourn- Example Pan-Am when we
have competition between different countries.
• National Tourn- majority of US tournament.
(Lot of TC reports have had the incorrect type)
TC Report
A TC Report must be completed and certification posted prior to
tournament. This report is a checklist to ensure that all requirements have
been checked prior to tournament. That means that all
requirements/checks have been performed prior to the tournament
(download latest from AWSA TC Resource Files (link to
http://waterski.online.fr/)
TC Report Issues:
• Incorrect version/yr used. If using the Emmanuel Lion Waterski
Homolgation Report, download latest yr.
• Type of Competition
International vs National (majority of US tournament).
• Jump –Check buoys- Survey and Computer verification not correct.
Record from Survey, then using the Jump Program, mark the check buoy
and record the X/Y coordinates. Should be within tolerance
(.10 class R /.15 classL /.20 classE)
TC Report Cont
TC Report Issues Contd:
• Jump Surface Deviation not being checked and actual measurements being
recorded- Use the Comment section to record additional information.
• Trick Course- a lot of sites do not meet the current rule (boat path on each
side of course –skier choose), this needs to be documented in the comment
section
Submitting TC Report:
All TC report are to be uploaded/imported in the Scoring Program, not to be
submitted as a separate report.
• Save TC Report by sanction# with HD appended (ex 15S001HD)
• If using electronic TC report, open using Word/Windows Notepad
and save as TXT file (ex 15S001HD.txt)
• Verify TXT file is complete
• Forward file to scorer prior to the tournament being submitted.
• Next few slides is an example (older)
Nat’l RECORDS
• There shall be no distinction between amateurs and
professionals. Example if a record is set in MM/Open should it
count for the skiers age division provided the requirements are
the same? Yes, Example OM Jump should not because the
ramp height difference?
• All Natl Records shall be submitted electronically. Upload files
to Adrive.com ([email protected]). Make a folder by
name and performance (example – Name 5 43off)
• NEW Starting 2015 -NO VCR tapes/DVD/CDs are to be
submitted unless there’s a special case were quality is
questionable.
• Notify TC Chairmen within 7 days
• Upload files within 21 days.
• Record Application identifies the data that must be submitted.
Note- when extra data is submitted it takes more space and
longer to sort. Only submit the required passes for record.
Nat’l Records Cont:
• Record Application- Latest rev on AWSA Web Site.
• NEW Scoring Program-Dave Allen has incorporated the Record
Application in the scoring program. It can now be exported
(excel format) from the scoring program which will provide
most of the data (skier information/judges/timing/etc).
The TC will have to complete (example- rope measurement,
skier meets rule for Nat’l record, survey data, trick ski width,
checklist, etc).
SURVEY
• A survey must be completed either by a TC prior to
tournament (no more than 90 days) OR
• By a licensed surveyor and submitted to TC Chairman no
later than 30 days prior to tournament.
• A 3 point survey for slalom is recommended, but a single
point with EDM is acceptable.
• It is the TC responsibility to ensure that nothing has moved
from the last survey (when tournament is held later within
the 90days). This can be done by visually inspecting and
comparing the survey data to the buoy location/position.
• Survey Spread sheets (by Dave Clark ) can be down loaded
from AWSA Web Site (under 3 Event, TC Resources). Lion
survey forms are with his TC Report.
SURVEY Cont:
Ref TC manual for tips on Surveying. Following are some guidelines:
• Instrument accuracy can not exceed 20 arc seconds
• When adjusting Survey instrument over an existing pin, move the tripod over the pin.
Adjust instrument 3 leveling screws to get CL, then adjust the tripod leg to get survey
instrument level. (will keep the instrument over the C/L).
• Find 0 reference mark (Left side looking at the lake) and record on data sheet for
future reference. Also record location of pin.
• If doing a single or 2 point survey, with one of the older survey instruments,
recommend verifying/recording all the angles first, then distance.
• Total Stations/EDMs, ensure the TP and Prism offset is correct prior to measuring
distance.
• If using a Prism in water , ensure the swimmer has a life jacket. If swimming or
kicking, the buoy will move and the measured distance will be off.
• Halfway thru the survey, and after completing the survey, check your zero point to
ensure nothing has moved.
• Input data in the speadsheet, calculate, and verify no errors. (O indicates no errors, #
indicate out of tolerance. Dave Clark spread sheet; on the right side, identifies the
amount out of tolerance. INPUT the opposite (-/+) and calculate and the spread
sheet will identify the angle and distance to were the buoy should be.
• Various spreadsheets that have been approved by TC committee (Dave Clark, Ed
Brazil, Emanuel Lion)
• Additional detail information is provided in each event section (slalom/jump)
TC Maintenance:
• 2 record tournaments (include the applicable events)
per year are required.
• A clinic or 2 Class C tournament can be counted
towards 1 record tournament if performing same role.
• TC Clinic every 4 years.
Judge clinic should include a TC Clinic, get a TC
Clinic Application along with the Judge Clinic
Application when doing in your area.
ANY TC can be the instructor.
• Scoring Program: Ensure your name gets added to the
scoring program as the TC no matter if it is a Class C or
E/L/R to ensure you get tournament credit.
EQUIPEMENT:
• Backup- 4 channel DVR
Model ECOR960 or 970-4F/1T2 ($312 B&H Photo)
Requirement 30fps per channel
Hi Resolution
704x480.
• All recorded video should have a minimum resolution
of (NTSC:704x480 - PAL:704x576)
• Caution: When purchasing a DVR ensure that the
playback is acceptable, several DVRs do not have a
quick way to “rewind”.
• Camera- Must be minimum 30fps
Equipment Cont:
• Jump and Trick Computer –Bob Corson- Programs are
free and can be downloaded from AWSA Webpage,
under TC Resources. Requires XP operating
system/computer. Programs will not work on WIN
7/8/Vista operating system. (new version should be out
this yr).
• SpashEye- Slalom/Jump and Trick –Donal system uses
Win7/8 Operating System. The Slalom does have an
option to track boat path.
• Felix Loreto – Jump/Trick program.
• Boetcher- Jump program.
Grid and setup for Loreto and Boetcher are similar to
meters setup. Corson and SplashEye are similar using
pixels in a grid to measure distance.
Equipment Cont :
EC Camera:
• Security camera (non fix lens) is most common.
• Security camera with fix variable lens (need to ensure lens will cover
area (ex Samsung model SCZ-2370N)
• An adapter can be purchase to mount an older camera zoom lens to a C
or CS mount on a security camera. Example B&H (NY) has an adapter
part# VA301 for $35 that mounts an older Canon Lens FD to CS Mount.
The lens needs to be “fixed aperture” and not auto or electronic.
• Lens: any where from 150 to 300mm will work for most sites.
• Dave Clark has some modified cameras that will fit in regular size
security box.
• Pelco Model EH4718 is large enough security box for any lens/camera
to fit. A plastic Bread box can also be used to protect camera/lens.
Equipment Cont:
Gate Camera
• Security camera with 10-100mm lens (depending on site)
CS mount lens up to100mm are standard
Boat Camera (slalom/tricks)
• Some of the new hand held camera do not have RCA out, only HD out,
therefore, need HD converter to RCA.
• If using a pylon setup, a security camera can be used if transmitting
out. A 4mm lens is too small, 6 is almost too close (which is common
being used). Need a 5 or 5.5mm.
• I-Phones have an APP that can be used to turn/off camera based on
speed/gps coord. that have been used for specific application (slalom).
• Hand Held: JVC Everio MS120 /Kodak PlaySport Zx3
• Records ELITE- Always have a hand held camera in boat!
Equipment Cont :
Gate/EC Transmit signal:
Several methods of transmitting signal back to judges.
Hardwire is the best method.
1) CAT 5 cable with Balun on each end; this provides power
and transmits signal over one cable (small/compact)
(Recommend baluns: Muxlab # 500024).
2) Siamese Coax (coax w 2 16g wire) also provides power &
transmit signal over one cable (Recommend for
permanent installation).
3) Standard Coax and run 2 conductor #16 wire along beside
for power
4) Standard Coax with battery at camera for power supply.
5) Wireless may work well at some sites and others will not
work at all due to high power transmission line or other
frequency interferences . One type is Omni Direction 2.4
GHz transmitters/receivers.
WIRELESS -TRANSMITTER/RECV
Transmitting from Boat:
• Place the Receiver close to water (approx 2 feet off water) and
in middle of course. For the best signal, use a Hi Gain antenna
at the end of lake (EC).
• WiFi equip for HD camera transmitting from the boat to the end
of the lake is available for about $1500.00
Equipment Cont :
Converter/Splitters:
• Tricks converting VGA output to RCA/S-Video to go into
trick timing computer capture card.
• LKV-2000 (from Monoprice)
• Tricks Splitter- Sending VGA out to several monitors
• VX-8204F (4 VGA out) or VX-8208F (8 VGA out)
(from Monoprice)
