Bob had compiled the agenda from the points raised by the Regions and it was agreed to work through in the order circulated. This is listed in appendix A.

A number of additional items were tabled.

Jump records / Speed Control

Bob had floated the idea of bringing this forward earlier than the already agreed date of January 1998 - however, the season was now over and it was agreed to leave the implementation to the date previously agreed.

Region EAME had suggested that if new records were to be established under Speed Control it might be an idea to also implement mandatory use of video jump measurement at the same time and remove the 2.1 metres add on. There was general agreement not to establish new jump records - they will just continue. The majority were in favour of leaving the records as they are - but now requiring speed control in order for any new record to be set. Mandatory use of video jump measurement was not agreed.

Speed Control at this World Championships

Will Bush the Chief Driver had been testing the boats and speed control - the altitude has a significant effect on the boats - and at this time they cannot guarantee that speed control will work here for men's jump. This is because power is down on the boats, however, the TC felt this would be the same for manual driving or speed control.

After discussion unanimous agreement was reached that speed control would be used for all events including men's jump. This information would be made public immediately..

Processing of Trick Records

The TC were not satisfied with the current methods which take a very long time and which are unfair to the skiers. Region EAME had suggested that trick records be handled totally by the judges at the site and they have to take the responsibility of their actions. The event judges will review the tape and re-judge the two passes at normal speed, check the times and scoring and would declare a record (or not) at the event. The review sheets and the video tape and the judges names will be made public. They will then send the video tape and sheets to Bob for a gross error check.

Should the score be amended on review then this new score would be the one used for the Ranking List. However, the original score will stand for the tournament score.

Several European officials were working on a freeze frame video for the last trick in time and Bob would be kept aware of developments.

World Cup Rules

At the last TC meeting it was agreed that all World Cup events should be L or R capability. We thought these were top events which deserved this status, however, this came to be not the case and some are on really bad sites where ranking is not an issue.

This was a political issue more than technical in most cases - the TC have no control over which sites are used - and it was important to hold the events in the public eye.

The TC agreed World Cup events should normally be L or R capability with 5 judges, however, an organiser may apply for exception where technical issues cannot be met. If the site was good enough to achieve L or R then no leeway would be given.

Terry Dorner has suggested the formation of a rules committee for the World Cup - Bob does not feel this is necessary. Perhaps there were organisation rules which need clarifying but the technical rules should come through here.

Jump speed interpretation for manual driving

Bob has published some words which are generally accepted.

See appendix B

Now speed control was in general use there may be a need to change the wording of the rules to accommodate machine operation. The manufacturers needed to work within the spirit of the rules.

The TC would monitor the need for changes as they occurred.

Three Jumps

The rules addendum would be changed to include our previous decision to allow three jumps in all rounds. Agreed that some skiers may not be aware of this and it would be published at this Championships.

Three Station Homologation Survey

Region EAME have asked for this requirement to be dropped in the belief that two stations are quite enough for a survey.

After discussion it was agreed to allow two station surveys for L tournaments and still require 3 stations for R tournaments. A visual check confirming the straightness of the course must be made.

World officials appointments

The TC feel it is appropriate for the IWSF President to formally notify the officials of their appointment by letter. Bob would ask the President to do this.

Rule 13.15

The wording in the jump timing chart did not quite agree with the wording of the rules. The TC reviewed the chart and made the following changes:-

S F mandatory if best distance, otherwise optional with protected score.

F S no change

F F no change

Bob would review the working of the rule and circulate amendments if felt necessary.

Rule 15.15c

Change "granted "in second sentence to "made". Agreed

Rule 14.01

Region EAME had suggested the 3 minute broken equipment rule was unnecessary and could be removed. The majority were not in favor of change.

Overall Points scoring

Region EAME were suggesting the use of a set of overall points based on the current World records.

Bob had already issued an overall ranking list using points from one tournament only and this had found favor with skiers. The TC agree this should be the method of ranking overall for the future.

Bob had circulated a paper on the Olympic format and the issues of "paper competitions". The TC could consider a separate overall competition with the top 4 or 5 male and female skiers skiing a separate round for overall. All like the concept very much indeed and it would be an excellent event.

This can be promoted as a World rule variation for competitions where the organisers wish to try it.

Overall records - yes, we like the concept, but realise we can't fix it here today. Agreed to establish a group of people to work with this - Alain, Jeffrey, Ron and Brenda were appointed and asked to come back to the next TC meeting with a definitive proposal for overall competition and overall records.

Proposed Overall Event Format (added after meeting - in spirit with the discussion)

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.

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

World Under 21 Championships

This is not really a TC matter but EAME wished to give their support to the idea. The EB will make the decision on this, not us. The aim is to achieve a developmental age championships.

Single Wire Floating Courses

Proposed words from EAME as requested -

Buoy support structure is rigid.

Buoy support structure is independent of but attached to the cable

The structure guarantees that the line of the three buoys in perpendicular to the wire.

The centre cable must be taut to assure a straight line.

Alain drew a diagram to explain how these courses were constructed and information on how to construct these courses would be published.

Addition to 15.11 Trick release

The AA Region were suggesting we make some allowance for a trick release which disintegrates or completely breaks!! The TC agreed the following wording would be used:

"If the tournament supplied release breaks and is no longer usable the event officials may grant a re-ride."

Homologation Dossiers

Region AA requested the submission time for homologation dossiers be extended to 30 days. This was accepted. Bob has been trying to achieve an electronic homologation dossier registration, but this is not yet proving very popular.

The aim is to make the dossiers available for public scrutiny. It was agreed Bob would alter the web dossier to show it just as a check list - rather than a full dossier with start list, results, etc…

The TC welcomed Andres Botero to the meeting. He welcomed the TC to Colombia and hopes that we have a great championships. We are in a changing world and a changing sport and we must continue to progress for the future.

The new TC address list would be circulated.

Speed Control for L Capability events

Bob had received a letter from the American Association which requested a delay in the mandate for speed control for L capability tournaments for 1998. The main reason for this is that of lack of product liability for the existing speed control systems. Bob suggested and it was agreed that we establish a limitation on the top scores for non speed control events - no scores over 6 @ 11.25 metres for men, 6 @ 12 for women - jump 55 metres for men and 40 metres for women. To be a one year exemption only for the 1998 season.

This was a possible solution for the Moomba Masters where outboards are used.

World Cup rules

Region AA believed world cup rules should allow 1.65 metre jumping if that is what the skiers want and the IWSF Rules allow it. This is a problem with the US Pro Tour who only have men 6 ft jumping. The other World Cup events did allow 1.65 jumping. The TC believed World Cup events must allow 1.65 m jumping for men.


All three regions agreed the record application from Cory Pickos for 11680 points is good and all tricks were in time. Record accepted - set at Mulberry Florida on 10 May 1997.

Jeff Rodgers - 5 @ 10.25 metres Bob has checked this and has accepted this as a new world record set on 30 August 1997 at Trophy Lakes Charleston. An application for 1 @ 9.75 metres is still pending as he cannot see the 9 metre pass on the tape, he will try to get it enhanced otherwise he can accept 6 at 10.25 metres as the record.

Members of the TC would be interested to learn more about the design of these good sites for slalom. What was the best design, depth, etc which makes for good performances.

Slalom Scoring

pg 54 after 2nd para third case give skier what he actually scored

i.e. asked 14.25, got 16, 3rd choice take 16 score and go to 14.25


Handle measurement so that once handle is measured it is in control of the tournament until the skier skis.

Joined by Brenda Nichols 3pm.

Jump re-rides

To receive any consideration of a reride request for conditions before the 180m, 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.

Athlete's section
Conflict of interest in an event

No conflict allowed on cash prize tournaments

Strong recommendation all other L and R

This would be included in the additional rules

  1. Recommend that normal practice is that a predetermined set down time is used for stopping the boat in slalom between passes.
  2. 3 jumps OK
  3. Slalom - no change
  4. Slalom repair - no change

For speed control - when it 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. This needs to be referenced in the rules so judges are aware of the difference between slow time and malfunction.

Creation of World Overall record

We have set a sub committee to work on this and come up with a proposal for next meeting.

Slalom gates - new format

Clint Stadlbaur suggested form entry buoys as an experiment - we would like someone to experiment and see how it goes. Try it out and report back.

Jump course

The skiers are requesting a 210 m buoy - in addition to 180 and 150. The TC agreed to make this an option now and give tolerances - colour yellow.

Homologation guidelines for video jump

We need to have some guidelines for all the relevant systems - but they are guidelines. Bob will prepare these.

All buoy timing

This works well with the Haggard system, but Eric Horton from Perfect Pass does not feel it is necessary. Brenda feels it will always work to the skiers advantage but knows it will be a nightmare to administer. It does assist the speed control to give a consistent speed.

We must aim for zero re-rides.

Agreed we will NOT proceed with 8 buoy timing.

The eventual goal of the TC was to have a system of speed control which did not require fall buttons nor any other button pushing, weighing skiers, etc.

Trying to cheat the machine once a buoy was missed comes under the unsportsmanlike conduct rules.

Use of competition site before a World Championships

Jeffrey believes the Championship site should be closed one week before the tournament to stop the problem of some teams training at the site when others did not have this available to them. This is the first Worlds without familiarisation and this has been an issue here. However, business is business and the site owners can do what they wish. We have little control over it.

Request from team captains for numbers in finals

Bruce reported on a written request from all team captains at the World Juniors to increase the numbers in the finals. However, the TC agreed to stick with 8 skiers and try to progress the Under 21 or Under 23 as an extra part of the World Juniors.

Seniors rules

Proposal from Pan Am to increase Senior 1 mens jump to optional 1.65m ramp height - no change in speed proposed. - Agreed.

Officials Nominations

Andres has requested in future that nominations for Chief Judge are submitted by each Region.


Andres would like the World Ranking List published closer to the World Championships - i.e. July, however, we feel it can't be handled administratively at this time.

The TC agreed to extend the number of Overall ranking skiers at the World Championships to the top 5 men and top 5 women.

A suggestion to limit the number of skiers in a final to 8 only was not accepted.

A suggestion from Max Kirwan regarding the use of the World Championships to stage sub region events - i.e. the Asian Championships - does not find favour with the TC but the EB will discuss it.

Trick sheet submission

The TC reached unanimous agreement that the submission for trick sheets applies to each series. So the officials will set a time for each series of skiers to submit their lists. This interpretation would become effective immediately.

Trick weighting

The boat will be weighted for tricks by 50 kilos for this World Championship tournament. 20kg each side and 10kg to be used for balance..

This is considered acceptable.

Election of the Chairman

The TC voted unanimously in favour of Bob Corson continuing as Chairman of the TC.

There being no further business the Chairman thanked the members for attending and for their work for the TC and formally declared the meeting closed.

Ad hoc meetings to discuss any specific subjects may be held during the week of the Championships.

Sunday, September 21 ad hoc meeting minutes.

  1. There was much discussion of Rule 2.02 regarding ties and the number of skiers to advance to the finals. Apparently it is unclear as there was discussion and also, it was implemented incorrectly by the panel. The desired goals are to have 8 team skiers in the finals and the top 8 skiers in the finals. Chairman Corson will try a re-wording for the council's approval.
  2. Rule 14.12 came under discussion as the panel allowed skiers in a tie to skip the set initial starting speed. Although this is not clearly permitted, it was agreed that this was a good idea and we will implement it in the rules.
  3. Optional use of different strand/weight ropes was discussed. This is clearly not allowed. The council felt that the 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.
  4. The management of trick lists was further discussed. After discussion it was decided that corrections should be allowed up to 1 hour before the start of the series.
  5. The TC discussed the use of weights in the boat for tricks. The general idea was that additional weights, if used, should be the same for the entire event as was done here. The TC will wait to see if there are further developments on this topic.
  6. It was decided to advance the date of the specification for the overall record to as soon as possible since this concept received immediate approval and will be implemented next season.
  7. The Council discussed the issue of announcement of technical specifications. It was felt that the type of rope to be used should be announced well in advance as well as the software version of the speed control unit.
  8. The issue of slalom scoring was raised by the athletes council and the desire to distinguish between 1 buoy where the skier is attempting to continue and 1 buoy where the skier crosses the buoy line with slack rope and then throws the handle. Helena Kjellander will ask other athletes for suggested wording.
  9. A WFLIP5F was submitted by Camillo Delgado with a video which was examined by the council. The council felt that the addition of one new flip at this time would unbalance the event, but also determined that a general trick review was needed. The course of action determined was to at the latest have a general trick review session at the next World Championships in 1999. However as that is a relatively long time away, we will seek the advise of a balanced selection of top athletes to give a combined recommendation on the balance and future direction of the event. As soon as we receive this, we will proceed with the review which will include athlete representation.

Appendix A Agenda

1997 IWSF TC Meeting Agenda (as of 6/30/97)

  1. Jump Records/Speed Control
  2. Processing of trick records
  3. World Cup Rules (L?,R?,?)
  4. Jump speed interpretation for manual driving


Dear Bob,

The EAME TC met in early July to discuss items for the World TC meeting. The following is a resume of our discussions:-

Change 13.01 and 13.05 to three jumps in the prelim round. Already agreed - just not correct in the rules addendum.

Note: I believe that Gill said that we could delete the next item as it is outdated, but I wanted to circulate it in the committee first.

Speed control

The problems of utilisation of speed control in Europe were discussed. The models are outdated as soon as we buy them! It was accepted that the manufacturers are trying to improve and develop so there is no way we can keep up to date. In the long term most favour buoy to buoy timing - but if speed control fails then it is impossible to hand time - so this needs careful discussion.

The immediate problem was for the World Championships where Bob says it will be used in all events. It is known there could be a problem with some of the top jump skiers who may refuse to ski under speed control. All agree that we must have an answer in advance - not leave this to a boycott at the Worlds. Gunther as Chief Judge needed to know what must happen and it was agreed he would make contact with Bob direct.

The EAME TC was not in favour of using speed control for jump at the World Championships because of lack of training, frequent changes, new parameters, etc.

Jump records with speed control

For jump records under speed control the TC believes the new records should be established from 1998 as previously decided - not now as had been suggested.

Jump records with video camera measurement

Given that new records would be established with speed control, it was felt this was an ideal time to also use the actual distance of the jump as recorded by the video cameras with no 2.1 metre add on. It was preferable to make all the changes at one time rather than establish new records with speed control one year, and then actual distance another.

Trick record review

All agreed with Bob Corson that the current system was cumbersome, time consuming and, ultimately unsatisfactory given the quality of the videos after conversion.

The EAME suggestion is that the review process of trick records is put into the hands of the judges for the competition at which the record was set. It will be their responsibility to review the video tape during (or at the conclusion of) the competition to check the performance of the tricks. Those officials will then sign their sheets and the record affidavit which will be published for all to see alongside the video tape. Should they revise the score of the run then this will be the score used for the Rankings List, but the tournament score will not change.

We believe this responsibility will be taken very seriously by the event officials given that their names and decisions will be very public.

Three station homologation survey

Goran Anderson had written to Bob Corson on this subject. The EAME TC concurred with the points he makes and wish the World TC to carefully review the need for a three station survey.

World officials - appointments

We need to find a better system for notification of selected officials to World titled events. Many selected this year did not ever hear officially from the IWSF.

Rule 13.15

The reride chart does not agree with the text of the rule. F - F should be MR only when best distance.

Also it was felt there is a problem with S - F where there is a MR only when best distance. The skier is disadvantaged because of SLOW so it should be MR only.

Rule 15.15 c

Change "granted" in second sentence to "made". Reasoning - the Chief Judge would be asking himself for permission!

Rule 14.01

Proposal to delete the 3 minute equipment repair.

But 14.15 to stay in - this is a different rule.

Overall points scoring

We wish to propose (again) to use the EAME overall scoring system which would allow us to establish a World Overall record. The scoring system would be based on the current World record scores and reviewed annually.

World Under 21 Championships

The EAME TC is in favour of the suggestion to establish a World Under 21 Championships which it believes will help to keep skiers involved in our sport. The problem will be which year to hold it - the calendar is already very full.

Single wire floating courses

At the request of the World TC the EAME TC suggests the following words be used:

Single wire courses are allowed where:

Buoy support structure is rigid

Buoy support structure is independent of but attached to the cable

The structure garantees that the line of the three buoys is perpendicular to the wire

The centre cable must be taut to assure a straight line.

Athlete Council Input

1. Conflict of interest:

At tournaments there has been officials judging an event that their child was competing in. This is not right, especially when it is an international cash-prize event.


Disallow judging by immediate family members (i.e. parent, child, sibling, spouse) to competitor in that event.

2. Inconsistent set down time between passes:

Several athletes discussed and felt strongly that in any event where there is a break between passes, the break or down time should be the same for all skiers. This is already done is tricks with the 30 second rule. But in slalom and jump, there has been problems with different skiers getting drastically different down times. In particular, after a skier asked for a reride for rough water the boat crew, from the chief judge's instruction, waited at least 2 minutes before the skier took the reride. All the other skiers were getting only 30 seconds. It appeared as a case of favoritism.


Require that chief judge determine what the set down time should be in advance of the event and have boat judge make sure it's being followed exactly.

3. Rounds with 2 jumps.

We believe that Rounds with just two jumps are dangerous. With only two, if the Skier has to pass or crashes on the first one, he/she has to go for broke on the second - and that is where jumpers get hurt. It also tends to produce shorter distances. We know that there may be a time problem at some events - but then we would prefer to see less jumpers rather than just two jumps per jumper. The build up for the Spectators is much better with three.


Require that all rounds of jump consists of three jumps.

4. Getting a full buoy in slalom even if you let go of the rope.

Getting a full buoy by skiing back to the wake and letting go of the handle to avoid the slack is not the same as riding it out. We feel that to score a full buoy you have to hold on and ski past the next boat guides.


Change wording of rule.XX.XXX

5. Slalom equipment repair:

Currently, if a binding breaks or screw comes out during your set you must continue skiing. This is dangerous and unfair. In jump you are allowed 3 min. to repair the damage to a binding or fin. slalom rule should be the same.

There really is no advantage to cheat and take 3 minutes to fix a broken ski since slalom skiing relies on continuity to ski well.

Discussion topics:

Should skier be required to run the whole pass to be able to repair and come back out at next rope length?

What if equipment breaks mid course?

Potential Solution:

Allow equipment repair as in jump. Make sure 2 simulation passes are run before skier goes back out on the water (see issue #2).

6. Speed Control:

Rerides when the system malfunctions as opposed to just running slow - at boat judge's discretion - should skier be allowed to improve? Yes.

Extra rules? Bob - this is your forte!

All buoy timing?

7. Creation of overall world record.


8. New format for slalom gates under investigation.

Clint Stadlbaur has put forth an idea to use high (40 cm) foam buoys at the gate to make it easier to judge the gates. The skier would hit the bouys (kind of like snow skiing) but since they are made of foam, it would not hurt.

Proceed to test? Any interest in this by the TC?

AA Region

On the 21st July I sent you agenda items from AA, I will include them again

1 Addition to 15.11 trick release

2 Problem with technical requirements for world ranking tournaments,

unable to supply homologation dossier within 7 days suggest 30 days.

3 Problem with ruling given for world cup rules,(unable to jump at 1.65m

4 Cruise control for outboard motors and ruling on 1st January 1998

5 World trick records for discussion

Pan Am Region

Here are the items that I would like to add to the agenda for the TC

meeting in Colombia:

Rule 14.14 paragraph 10: add....take credit for the actual pass skied.

Homologation guidelines p. 72: delete the word immediately

Add a rule to the jumping that would----waive any rerides for conditions

prior to the timing course if the skier actually took a jump.....

Authorization for rerides in tricks for speed and path should be given to

the Boat Judge as in jumping(i.e. rule 13.09)



Couple of things today.

First, I neglected to mention previously that we'd recommend adoption of "All Buoy" timing for slalom whenever automatic timing systems are being used. I presume you've seen the formalities of how that translates into the existing rule "first segment" and "second segment" language, based on the concensus score for each pass. If not, I'll dig that out and send it to you. What this eliminates is the Fall/Fast quandry mentioned in my other note to Charlotte of earlier today. Given the relative lack of experience with this process, inclusion of "enabling language" would probably be the best approach for now.

While I've not personally experienced this myself, I did have a lengthy discussion recently with a proponent, and got satisfactory responses to all of my, "But what about ......." questions. Other than the inevitable learning curve issues, sounds like it should work well. Mechanically implemented in terms of today's systems, this can be accomplished without requiring sponsors to buy any additional equipment, to my surprise. Let me expound for a moment, if you've not heard this aspect before. Most current Slalom timing implementations involve two magnets on at each end, plus a 1-ball and 3-ball magnet going each way -- total of eight magnets. The cute idea is to equip the boat like you do for jumping, with coupled pickups on both sides of the boat, then just re-organize the existing eight magnets so that there's one on every gate, which would typically be down just one side of the course. Then you get a trip at each gate, going both directions. Then all you need is a smart watch or a smart computer to analyze the data and report the pertinent results.

Next, as to the added jump skier reference buoy mentioned previously, I've chatted with a couple of the 210m buoy proponents, and they all agree that the same 30m interval which is used between the existing 150m and 180m buoys would be reasonable to extend the reference area backwards. Probably better to just say its at 210m, so that everybody does it the same way. Allowing local options would just cause confusion.

Finally, here's the short version of the proposed language on a Precision Standard for Video Jump measurement systems. The original E-Mail note, which discusses this at more length, follows.


The proposed operating rule is: Any video jump distance measurement system must be configured such that the maximum differential in jump distances which would result from one-pixel movements on the video screen -- either of any of the required reference point markers, or of the landing point marker itself -- and in either the horizontal or vertical direction -- not exceed the value "X" at any point in that "operating field of view", which means the central 80% of the screen area. The value of "X" would depend on the class of the tournament. Here are the proposed values:

World Record (Class "R"): 10 cm.

Standing List (Class "L"): 15 cm.

Local Tournaments (Class "C") 20 cm.

As an aid to evaluating any proposed Corson Video Jump System site configuration against this standard, the AWSA Technical Committee has prepared a Video Jump System Planning and Analysis model in the form of a spreadsheet template. Alternatively, any actual setup can also be evaluated against this standard by moving the reference markers and landing point markers, and observing the reported changes in the calculated landing location which results from such movements. Such manual evaluations need to be systematically conducted, throughout the expected operating range of the setup.

Appendix B

Manual Driving Interpretation

Guideline for Boat Judges for manual Driving in the Jump Event

This guideline is meant to give some more specific guidance to boat judges in the jump event.

First, the most important responsibility the boat judge has is to the safety of the skier in monitoring the water conditions and other potential safety hazards.

According to the rules, the driver should be driving a constant speed in a straight line with no intentional speed changes in order to enhance the skier's performance.

The boat judge needs to monitor the speed of the boat. The indicated boat speed should not be greater or less than 1km from the skier's selected speed. For purposes of this guideline we will focus on the speed not being more than 1km higher than the maximum speed allowed. The boat judge will monitor this by observing the speedometer for a few seconds at the appropriate critical times, such as during the cut to the ramp and during the counter-cut. As this is a guideline, the boat judge will have to use his best judgment. As an example, if the skier is pulling and the driver has given gas to compensate for the load and the skier unexpectedly or suddenly stops pulling and the speed jumps up and is then immediately corrected by the driver, this is probably not too great a cause of concern. If the driver is applying power and the speed is increasing and greater than 1 km greater than maximum while the skier is in the power portion of the cut or counter cut, this is definitely a problem.

If the boat judge observes such a problem, he should inform the driver that it is a problem and ask the driver to correct it. Also, if the judge feels that the skier has been given an unfair advantage, he should, in accordance with the rules, call for a mandatory reride. If the practice continues, the boat judge should call the Chief Judge and inform him of the situation. The Chief Judge should inform the driver that if he cannot drive in accordance with the rules, he will be replaced. If the driver needs further warnings, the Chief Judge will replace him and also note the replacement in the Chief Judge's report.

A definite problem that the boat judge will face is determining the criticality of the problem. The event is so dynamic that an un-anticipated let-up by the skier might easily cause the speedo to jump up 1.5km. We are asking that the boat judge use his best judgment to determine if the problem is due to the normal dynamics of the situation or it is due to a planned attempt to circumvent the rules based on his experience and these guidelines. It may also be that the driver is not capable of driving within the rules and not necessarily have improper intentions. Regardless of that, a driver who can follow the the letter and the intent of the rules must be used.
