IWSF 1998 Tournament Rules Addendum

Feb. 26, 1998
This is the official addendum to the 1995 Rules as certified by the IWSF Tournament Council on September 15, 1997. The addendum is a compendium of the 1996 Addendum and 1997 Addendum and the further rules modifications made by the IWSF Tournament Council at its annual meeting. Those rules added to the 1998 addendum are bold-italicized and noted as 1998.

Robert K. Corson, Chairman

Rule 2.02

1998

Replace description of who qualifies for the finals

Basic Rule

The first eight placed skiers based on the results of the preliminary round, shall be qualified to ski in the final round of that event. If, within these first eight placed skiers, there are any non team (individual) skiers then an equivalent number of the next highest placed team skiers shall join the finals so that there are eight team skiers in the finals.

Team skiers

The eight highest placed team skiers in the Preliminary rounds will proceed to the Final round. (but, see Ties below)

Individual skiers

Individual skiers may go into the final ONLY if they finish in the first eight places of the Preliminary rounds. (but, see Ties below)

Ties

Where only team skiers are involved. In the case of a tie for any position which may result in more than eight team skiers going through to the final round there will be a run off between the tied team skiers so that only eight team skiers go into the finals.

Where team and individual skiers are involved.

In the case of a tie which involves individual skiers where more than eight skiers (team or individual) are placed in the first eight places (e.g. 4 skiers tied at 6th) a run off shall be held between the tied skiers to establish a clear cut off at eighth place. Any resultant tie(s) shall also be run off until a clear cut off at eighth place is achieved. Any individual skier involved in the run off and finishing below eighth place will not proceed to the finals - see basic rule.

2.03: Schedule of Events (eliminate reference to familiarization)

Not later than two months before the start of the tournament, the Tournament Chairman shall send to each affiliated Federation, by air mail, a schedule showing the days on which the tournament events will be held. The schedule of events for both the preliminary and final rounds shall be drawn up by the Chief Judge, the Chairman of the Tournament Council and the Tournament Chairman and posted prior to the start of the first event. This list shall include starting time for each day. A schedule of starting times for individual events, if shown, shall be for the guidance of the contestants only, and any deviation shall not constitute a change. It is recommended that jumping be scheduled as the last event in both the preliminary and final rounds.

2.05: World Championships Entry and Administration

Change all references to familiarization or official familiarization to "start of the first event"

If the official entry forms are not received prior to the 24 hours before the start of the first event, the Federation's skier's places in the draw shall be determined by the Chief Judge without reference to their qualifying scores.

2.06: Official Familiarization (Delete this rule)

Rule 2.08

Once homologations starts, use of the site is under the authority of the Chief Judge until the completion of the tournament.

4.01

1998

b) Ranked on the IWSF World Rankings List in the top 8 in any event or ranked in the top 5 in overall

To qualify as a World Record Holder, the skier must have performed the record at least 45 days before the first day of the World Championships and have his performance ratified by the Tournament Council and the President of the IWSF 15 days before the first day of the World Tournament.

1998

5.06 Overall Event - An optional method for Overall Competition

The overall event shall consist of a final round only with each competitor receiving one round in each of the three events, slalom, tricks, and jump. Separate men's and women's divisions will be held. In a normal (World Championship rules) tournament, the contestants with the top 4 overall scores from the preliminary rounds of the event competitions will advance to the overall final. The start order in each of the three events shall remain the same which shall be the reverse of the overall placement in the preliminary round. The contestants shall slalom first according to all of the rules of the slalom event. This will be followed by tricks and finally jump. (In the spirit of the rules, the optional lower heights of the jump should be allowed, if requested, which would potentially change the start order of the jump portion. If possible this should be avoided - potentially the top overall skiers will all be using the higher ramp setting.) The skier with the highest overall score based on performances in this round only shall be the winner. Any tie will be resolved by first using the jump score as a tiebreaker. If they are tied, then the tricks score will be used as a tiebreaker. If there is still a tie, then they must also have tied in slalom and the tie will be resolved by a runoff in the jump event.

The overall event will normally consist of both a men's and woman's event. They will run together in that the running of the events will be women's slalom then men's slalom followed by women's tricks and then men's tricks followed by women's jump and then men's jump.

The event scores produced in this overall event will in no way be used for team scores.

In the preliminary and the final, the scoring method for overall qualification only will be against the following fixed "best scores". Team scoring is unchanged. Using these fixed scores allows the establishment of Overall records. The judges may, before the start of the overall final, decide to revert to a winner equals 1000 points standard system if the conditions warrant it in that skiing against a fixed standard would unfairly benefit one event over another. Standard notification rules apply.

Potential options for non-World Championships rules events.

  1. The competitors may be invited directly rather than being selected from a preliminary round.
  2. More than 4 competitors may be in the event
  3. Mandatory maximum jump height may be required

6.01: Chief Judge - Appointed Officials.

At least six (6) months prior to the start of official start of the World Tournament, the President of the IWSF shall appoint the Chief Judge for the World Tournament from among the Chief Judges proposed by each Region Tournament Council.

6.02: Choosing Appointed Judges

A total of 10 judges shall be selected.

Each region will nominate a person for the 10th judge to be selected by the Chairman.

6.03: Event Judges

For the World Championships, the Event Judges must be chosen by the Chief Judge from among the Appointed Judges, preferably as follows:

For Slalom - no more than two judges from any one Region.

For Tricks - the best panel appropriate for the level of trick performances

For Jumping - one Judge per Region.

At other tournaments, the selection to the event judges shall be governed by Region administrative practice.

"6.04 The scoring sheets of each judge for every skier shall be made available for a period of 30 minutes for inspection by the team captain as soon as the provisional results are posted. Under the team captain's responsibility, a skier may view his own scoring sheets.

If a skier's score sheet is changed based upon this review, the changed sheet will be available for inspection for a period of 15 minutes after the revised results are posted assuming that this would not be less that the initial 30 minute limit. Each time a sheet is changed, it will be available for another 15 minutes for review."

7.06: Safety Boats

Two safety boats shall be used during all events.

7.08: On Site Medical Facilities

The Safety Director will appoint a Tournament Medical Officer who will undertake to provide the following services:

1) A suitably qualified medical officer will be in attendance during all tournament events.

8.01: Team Representative

Each Federation shall select a team representative whose name shall be given to the Chief Judge before the start of the first event. The team representative shall represent all skiers from his federation. An alternate team representative may also be named.

10.03 c) Devices affixed to the ski intended to control or adjust the skiing characteristics of the ski are allowed as long as they are fixed in that they do not move or change during actual skiing.

10.04 a)

Weight per meter: 23.0 grams/meter maximum

Breaking load, minimum = 590 kg.

Elongation at 115kg tensile load: 2.4% +/- 0.8%.

The gauge length shall be set at 5.5 kg tensile load

1998

10.04 h) add

Organizers should supply a rope of a certain allowable specification and continue to use ropes of that same specification for the entire event, both preliminaries and finals. This does not prevent using ropes of different specifications for different events as long as a rope of the same specification is used for the entire event.

1998

10.04 g) new diagram

Rule 10.07 Speed Control

Speed control will be required for the World Championships. The specific make and model of speed control will be announced when the boats are announced for the World Championships (see 10.01 e).

Further, speed control will be required for all Ranking list and Record tournaments starting Jan.1, 1998 and for the 1997 World Cup tournaments.

Some of the important points are as follows:

1998

(a)If speed control breaks then go to manual. If a replacement unit or boat is not available, or the unit cannot be quickly repaired, then the tournament shall be continued with manual driving with performance restrictions for those performances done with manual driving. (These restrictions are noted in the Additional Rules section notes)

1998

When the speed control cuts out or fails to operate or is a deviation from normal operation (i.e. a malfunction) the skier is entitled to a re-ride for failure of equipment and can improve the score.

(b)If the unit allows, the speed may be micro adjusted a set number of specific speed steps to compensate for wind or current conditions on a pass by pass basis under the control and/or observation of the boat judge.

(c)The principle job of the speed control is to provide independence of the manual operator and to give in tolerance, constant speeds, as close as possible to actual times.

(d)The Boat Judge and the Driver shall jointly agree on the setting of the speed control and the allowed adjustments for wind conditions, etc., with the goal of having the machine produce actual times for each pass.

11.02: Tolerances (see also Rule 1.11)

...

In the jumping event, it is the responsibility of the driver to drive the boat at the constant speed (as selected by the skier (see Rule 13.04)) throughout the entire course. The driver may not intentionally increase or decrease the speed or intentionally allow the speed to increase or decrease. He must maintain a constant speed. If, in the opinion of the boat judge, the speed before or after the timing course was a disadvantage to the skier, he will be given the option of a reride.

Rule 12.01

In 12.01 put reference to video buoys 3rd sentence

No buoys or markers other than those indicated by Diagrams 1,2,3,4 and 5 and video jump measurement buoys are permitted within the competition area except to mark safety hazards, landing or starting areas, or turning buoys.

The entrance of the courses for each event are defined as follows:

Slalom: The start gates of the slalom course on the first pass

Jumping: The 180m buoy on each pass

Tricks: The first trick buoy on each pass

13.01: General Jump Event Conditions

1998

The skier shall be entitled to three jumps or passes or falls from the time he starts in the preliminaries and three jumps or passes or falls from the time he starts in the finals.

a) Women jumpers will have the option of choosing either a height of 1.65 m. or 1.50m (see Rule 13.02d).

b) Men jumpers will have the option of choosing either a height of 1.65 m. or 1.80m (see Rule 13.02d).

Only the length of the jump will be considered no matter what ramp height is chosen by the skier.

A skier may not change his chosen height of the ramp for the final round if he qualifies.

Skiers jumping at each height will be drawn together and will ski before those jumping at the higher height setting in both the elimination and final rounds.

1998

A contestant may refuse to enter the jump course by throwing the handle in the air. He shall not be penalized for so doing providing this refusal was for a reason judged acceptable by the Event Judges. To receive any consideration of a reride request for conditions before the 180m buoy, the skier must throw the handle before entering the course. Once having taken the jump the skier loses all right to a re-ride for conditions before the 180 m buoy. The skier must be ready to ski immediately upon the boat's return. (con't)

Rule 13.02

d) Ratio of ramp height at take off edge to ramp length out of water:

-0.275 +/- 0.003 or 0.255 +/- 0.003 for Men, at the skier's option

-0.255 +/- 0.003 or -0.235 +/- 0.003 for Women, at the skier's option

Ratios are to be computed on both sides of the ramp, and the ramp height at the take off edge at the two corners may differ by no more than 2.5 cm. (See

Ramp Setting Chart).

e) Jumpers must notify the Chairman of the IWSF Tournament Council, the Chairman of the Region Tournament Council, and the organizers, on the official entry form, what their choice will be for the ratio mentioned in d) above.

13.10 add

"If the official resolution of a particular set of sightings, according to the above rules, produces an official wide triangle, and that set of sightings included a spread in excess of the 0.6 meter test limit AT ONLY ONE of the meter stations, which yielded the smaller triangle size by using the average rather than the shorter reading alone, then the longer reading from that station may be tried alone, and used as official, if it eliminates the wide triangle."

Rule 13.11 (add)

Alternatively, if video jump distance measurement is used, the distance shall be measured to the skier's point of impact in the water closest to the ramp (first point of impact) and then an adjustment offset of 2.1m shall be added.

For the video system, there shall be two designated officials (from different countries at international tournaments) operating the system who shall jointly agree on the impact point. The calculated distance shall not be displayed until the impact point is decided upon.

If video jump measurement is used, video backup methods (video taping) may be used or a standard meter system may be used.

Rule 13.15 paragraph 2

In addition to the official timer, at least one other timing device shall be operated from the boat unless not feasible in which case it will be from the shore. In the event that the official timer fails to get an accurate time for some reason, the backup timer shall govern.

Rule 13.15 Add between paragraphs 4 and 5

If the second segment is fast on a successful jump but the distance recorded is less than previous or following jumps in the round by the skier, then a reride will not be awarded.

Rule 13.15 (last paragraph)

If a rerun is given because of a faulty boat path or an error in speed, it must be taken immediately, and the Boat Judge must hold up an appropriate flag during the return pass to indicate that a reride will be taken on the jump that has just been completed. If there are more than two (2) rerides, the skier shall have the option of asking for a five-minute rest before continuing.

14.06: Buoys

d) Slalom skier and gate buoys shall be 22 to 28 cm. in diameter. 23 cm. is recommended. These buoys shall also be generally spherical above the waterline.

g) Buoys shall be fastened so that they have 11-17 cm of height out of the water (11.5 cm recommended)

Rule 14.07 paragraph 3

The skier may elect to waive all passes below a selected rope length (or speed should the Appointed Judges lower the minimum starting speed). In such cases the skier may notify the dock official of his selected rope length (or speed) any time before he starts his run. A skier who fails to select his starting speed at the specified time, will start at the maximum starting rope length and minimum speed for the event. Further optional selection of slalom passes is also allowed. If a skier misses in a pass that follows an optionally skipped pass, he/she shall be scored as if the buoys were scored in the pass following the last completed pass.

1998

Rule 14.12 add

The tie breaking run shall begin with the scheduled speed and rope length of the last complete pass and conclude with the first miss. If another tie results, the tie shall be run off in the same manner with another new drawing for order. This process shall be repeated until a winner is determined. The skier may optionally skip any pass in the run-off.

Rule 14.14 paragraph 4

Where the applicable speed is slower than allowable on any pass, a rerun shall be mandatory. If either time is too slow, a reride is mandatory. If the pass was not a perfect pass, the skier may not improve his score over that obtained on the slow pass, unless the speed is so slow that it is equal to or below the fast tolerance of the next slower pass. One exception to this is, if the skier scores more than 2 1/2 and the 1st segment is fast and the 2nd segment is slow, or the 1st segment is slow and the 2nd segment is fast, a reride is mandatory but the skier may improve his score. If the pass was a perfect pass (score is 6, skier to continue), the skier may choose to proceed to the next pass instead of repeating the pass. If the skier then makes a perfect pass, he receives credit for both passes. If the pass is missed, he will receive credit for the buoys made as if it were the lower, skipped pass.

1998

Rule 14.14 paragraph 10

In the event a contestant inadvertently receives a speed slower or a rope length longer than the intended pass, the skier will be given the option of proceeding to the next pass which follows the intended pass (assuming the pass taken was perfect), or taking a reride, or receiving the score for what was actually skied.

Rule 14.14 paragraph 11

In addition to the official timer, at least one other timing device shall be operated from the boat unless not feasible in which case it will be from the shore. In the event that the official timer fails to get an accurate time for some reason, the backup timer shall govern.

Rule 14.14 paragraph 8

If there are more than two (2) rerides, the skier shall have the option of requesting a five-minute rest before continuing.

14.15: Damaged Equipment

If a skier has damaged his equipment during a run that leads to a reride, he must be back on his skis within 3 minutes from the time the reride has been granted or he is not allowed to continue in the round. If the skier is not allowed to continue, in the case of a mandatory reride, the pass that brought about the reride is scored as 0 unless the score was 2 1/2 or greater and the first segment was OK or Fast in which case the skier is scored with 2 1/2.

If the skier is not allowed to continue, in the case of an optional reride (and the skier is not back on his skis within 3 minutes), he is credited with the score obtained in the run that brought about the reride.

15.01 1st paragraph eliminate the last sentence "If a skier notices..."

A contestant may refuse to enter the trick course by throwing his handle in the air or by being released by the quick release operator by means of a pre-arranged signal before entering the trick course. If, in the opinion of a majority of the Event Judges, this refusal is without acceptable reason, the skier loses the right to that pass. The skier must be ready to ski immediately upon the boat's return.

If the skier's refusal is accepted, the boat must repeat the regular path and once again head for the trick course.

15.08: Proceeding through the two trick passes

The boat shall follow as closely as possible the path specified by the

Judges for the event, such path to include the preparation time before each

pass. The second pass shall be in the opposite direction from the first

pass. A skier may neither return to pick up a dropped ski nor add a second ski

between passes.

At the skier's option, if he did not fall, the boat may stop between passes for a maximum of 30 seconds, however, he may change equipment in the 30 second set down period. The 30 seconds shall start when the boat gets to the skier. At the end of 30 seconds the skier must be in the water ready to go or he loses the right to his second pass.

If a skier refuses to enter the course under the provision in Rule 15.01, and he is not ready when the boat returns for him, he shall be considered as having fallen.

1998

Rule 15.11 last paragraph

A skier may accept a tournament-supplied release mechanism. In that case, he takes all responsibility for the device. If the tournament supplied release breaks and is no longer usable the event officials may grant a re-ride.

1998

15.15 c

c) In circumstances which the Chief Judge regards as exceptional, the Event Judges may review the tape. This request should not be made if the intention is to change a Judge's decision under 15.11 (a) and (b).

15.15 add

Any time there is a 3-2 split on the last trick in time on a run of over 10,000 points, a designated qualified judge shall be appointed by the CJ to review the video. If the designated person does not agree with the judges' decision, it will then be reviewed by the Chief Judge. If both the video reviewer and the Chief judge agree, their decision will stand otherwise the event judges have to review. The official appointed to review the video shall be assigned for the whole event/series.

1998

Rule 15.16 - modify

The Chief Judge and Chief Calculator shall determine the exact time when the list must be submitted for each seed of the elimination rounds and the final rounds. Corrections may be allowed up to one hour before the seed.

15.19

b) Add as follows:

For wake flips with body rotation (#54, #55), the body rotation must be done simultaneously with the flip, not before or after. The WFLIPBFB is not considered a 180 degree turn either for purposes of declared tricks as referenced in Rule 15.16 or for reverse turns as described in 15.19 c). Additionally, for the WFLIPBFB, the reverse must land in the opposite wrap or turn in the opposite direction. Also, specifically for the WFLIPBLB, the stepover portion of the trick must be done simultaneously with the flip and the body rotation.

1998

Rule 16 - RECORDS

16.01: What Records are recognized The IWSF shall recognize World records for tricks points, slalom performances, jump distances, and overall points for the Men's and Women's divisions. The Regions may, in addition, recognize Region records under the same standards provided for World records. The Regions may, however, recognize records for division other than those recognized by the IWSF. The Region in which a record may be recognized shall be determined by the nationality of the skier rather than the location of the tournament.

1998

Rule 16.05a Overall Records

The highest scoring overall performance performed in a tournament shall be a new record if it exceeds by 0.01 point or more the official record performed on a date before the tournament. If the score is equalled, the skier will become co-holder of the established record. The scoring will be based on the scores noted in Rule 5.06

1998

16.07 c (add)

In jumping, a video jump measurement system is required. Currently there are three approved systems. One system is the photogrammetric based system requiring one camera and grid buoys developed by Bob Corson (USA). Another is the two camera trigonometric system developed by Olaf Boettcher (GER). A three camera trigonometric system developed in Japan was also approved.

The homologator will measure the exact position of the video jump buoys in the video jump buoy course (if used).

A video jump record submission shall include the survey, a copy of the video, a gif formatted file of the record jump, a gif file of the video grid box if in the record jump gif any of the buoys are obscured, and all configuration and setup files appropriate for the system being used to allow independent verification.

17.02 add

If it is not feasible to place the judges tower at the prescribed angle, a video camera may be mounted at the proper angle and the live signal fed to a monitor that the tower judges can observe the gate and the gate judgment will made from the monitor. The signal will be taped so that review is possible.

Page 82 Ranking Lists

WORLD RANKING LIST DESCRIPTION AND SCHEDULE

The World Ranking List is a list of the best men and women skiers in each event ranked by performance. A Junior Ranking List is also produced for skiers meeting the Junior age criteria and based on skiing under junior rules. The ranking is based on the average of each skiers' two best scores from two separate tournaments. Only one score in each event is considered from each tournament. Each IWSF Federation sanctions Record Capability or World Standings List tournaments from which the performances are taken. Performances are taken from score books and submitted by the sanctioning Federation or Region. Submitted Any trick score over 10,000 points must be performed in an R tournament to be qualified for the Ranking List.

A separate ranking list overall will be calculated on the basis of the World tournament records on a tournament by tournament basis. This means that an overall score can only be achieved for the list by having an overall performance at a tournament. Event scores from multiple tournaments will not be combined to calculate an overall score. This will be done alongside the existing ranking list for one year on a trial basis.

Scores shall be submitted containing at a minimum the following information:

Field Example
LAST NAME PRICE
First Name Paul
ID number
GROUP 2
COUNTRY GBR
SEX M
TOURNAMENT 95GBR04

Special Condition Code J

The ID number, if not implemented, should be left blank. However, all Federations are encouraged to implement an ID number as soon as feasible.

The alt_score is to be used to show the slalom score in buoys at line length to confirm the buoy count. A slalom score of 51 for a woman skier would have an alt_score equal to 3@12/55

Year of Birth is only mandatory for Junior age skiers.

Special Condition Code now has only one case and that is equal to J if the skier is of junior age and the event was run with junior men jump rules (max speed 51 kmph, max ramp height 1.65)

Ranking Lists are currently published three times a year for results less than one year old on the following dates: April 30, July 31, and October 31.

The normal procedure will be that performances are submitted any time up to 30 days after the results closing dates (listed above). A preliminary list will then be published. Certified changes may be submitted for 30 days after the publication of the preliminary list. At that point, results will be closed and a final list shall be published.

The lists shall be published on the World Wide Web at the IWSF Home Page

If you do not have access to this method of publication, contact your federation or region administrator for a copy of the preliminary or final list.
