TECHNICAL RULES - WATER SKI RACING

RULE 1: GENERAL Top

1.01 These rules set forth are the Technical Rules for Water Ski Racing sanctioned by the International Water Ski Federation
(IWSF). With the exception of entry requirements and other administrative matters, the Regions must follow these rules for their sanctioned races. It is requested Federations establish rules as close to these as possible. Whenever the masculine is used, the same shall be construed as meaning the feminine where the context so requires.

1.02 These rules are concerned with:

(a) Circuit Races (more than 2 laps)

(b) Distance Races (point to point)

(c) Time Trials.

1.03 Exception to the rules - complementary rules

Where compliance with the rules is impossible and where complementary rules in connection with the circuit are needed, complementary articles will be set forth by the organisers, in agreement with:

1. for World Championships, the IWSF Racing Council

2. for Regional Championships, these complementary rules have to be sent to the Regional Racing Council, together with the Technical Dossier.

1.04 Interpretation of the rules

Questions of interpretation of the rules shall be referred to the IWSF Racing Council or their representative where possible. An arbitrator may be appointed for IWSF rule interpretation. Any interpretation made by the IWSF Racing Council as a whole shall be considered final. Otherwise the interpretation shall be made by a majority vote of the Appointed Judges, and the Chief Judge shall make a report to the IWSF Racing Council for World Championships, and for Regional events to his Region Racing Council. The Chief Judge shall make a detailed homologation to the IWSF Racing Council, or to his Region Racing Council.

1.05 Amendments to the rules

The rules may be amended at any time by the IWSF Racing Council. They shall become effective sixty (60) days after they are sent to the President of each affiliated Federation which must be at least 60 days before the 1st January in any year. The same provisions will apply in respect of Region sanctioned Races.

1.06 The inability for one reason or another of a country to attend the World or Region Racing Championships (including political reasons) doesn’t require the entire competition be cancelled or postponed or that the titles are any less World or Region titles.

1.07 TThe World Racing Championships shall be held biennially in odd numbered years. The World Championships will be a four race series with only the three best scores counting to individual overall standings. All four scores will count towards overall team standings

  

RULE 2: DIVISIONS OF COMPETITIONS Top 

2.01 The competition stands open to all skiers, either man or woman. In the final results each classification has to be made for each sex separately. Eligibility to represent a Federation at a World Championship is governed by the residential qualification of each individual country.

2.02 A Federation may nominate a Team of 3 men + 1 Reserve 3 Women + 1 Reserve. Each Federation will nominate in each classification a Team of 3 skiing members. The Team Captain will nominate the grid position for the first round only.

2.03 Reserves: In the event of a member of a Federation's Team being unable to ski, the reserve skier may ski if a boat is available. Individual points cannot be carried forward from the retired skier to the reserve skier.

2.04 Points Score for Teams The first two best results in each of the Men's and Women's Races from each Federation will receive the points for the Team Trophy. If a Reserve skier replaces a Team member his/her points will be included in the Team's Points Score if his /hers is one of the two best results for the federation in his/her race.

2.05 The reigning World Champions - male and female - are eligible to ski in the World Championships if entered by their own respective Federations, but cannot accrue Team Points unless selected as a member of the Federation Team. In the case of a World Champion entering as an Individual and not in the Federation Team he will start on the back grid. This rule does not apply to Junior World Champions.

2.06 Junior Competition in World Championships: A maximum of 2 Boys and 2 Girls from each Federation will be permitted to compete in a Junior Competition at World Championships - NO RESERVES. Race to be 30 mins + 1 lap duration. There will be an Individual Trophy only for Juniors. NOTE: Scores for Juniors will not be accumulated towards Senior Teams Point Shield. Junior skiers will not receive team medals.

The maximum age of any skier participating in the Junior World Championships is 16 years as at the 31st December in the year preceding the Championships. This means that the last year of eligibility of a skier is the year in which he/she has his/her 17th birthday.

 

RULE 3: ENTRY REQUIREMENTS Top 

3.01 Each competitor must have in his possession an international licence issued by his Federation, endorsed by Region Racing Council on behalf of IWSF.

3.02 Each Federation shall notify the organisers of the names of their teams participating. The Chief Judge shall be notified of the Team members by the Team Captain prior to the start of each race.

3.03 A Team is defined as a skier, driver and observer. One member of the boat crew and the skier shall be of the entering team’s nationality. Each skier, driver and observer must notify the organisers of their blood groups.

3.04 Race Organisers must provide facilities for third party insurance for entrants and each boat must be insured against third party risks for a minimum of SF1,000,000 or the equivalent in local currency. The current policy of insurance with a valid renewal receipt for the same must be produced before or at the time of inscription.
