Racing Judgement Systems

A finish is confirmed when a rider crosses the finish line while riding their motorboat. The placings are determined in the order in which the front end of each motorboat crosses the finish line.

• All riders must cross the finish line within 30 seconds of the time the leading riders reaches the finish line. If the referee determines that a riders is unable to finish within the 30-second limit, they may declare the riders disqualified.

Prohibition of contact refers to situations where, during straight run or turn-mark rotations, a motorboat loses speed or experiences similar issues, leading to a collision (contact) with another motorboat and causing damage.

• Speed Loss: It refers to a condition where the motorboat’s speed drops significantly below normal levels due to cavitation, engine stop, or other factors. It also includes cases where a motorboat interferes with another motorboat due to capsizing, sinking, or falling water.
• Collision: It refers to a contact with another motorboat within a distance where avoidance was possible.

A change of direction occurs when two or more motorboats *approach and run side by side, and one motorboat changes direction laterally, obstructing the path or causing damage to another motorboat.

• 
  01 Zigzagging (Course Change) Situation

  • On a straight path, boat No. 1 zigzags, obstructing the progress of boat No. 6 and causing damage
• 
  02 Forcing Outside Situation

  • On a straight course, boat No. 4 forces boat No. 3, which was running parallel, towards the outside, interfering its progress and causing damage

To rotate around the turn-mark means that the centre of the motorboat must turn around the centre of the turn-mark. The motorboat must rotate around the turn-mark in an anticlockwise direction. When two or more motorboats are turning the turn-mark simultaneously, the motorboat on the outside must provide a safe space for the motorboat on the inside.

• During a rotation, boat No. 1 hits the turn-mark and causes damage to boats No. 3, 5, and 4

Accident Boat

• An accident boat refers to a motorboat that cannot continue to race normally due to capsizing, sinking, malfunction, rider injury, or falling into the water during the race.

If there is a rescue boat or an accident boat near the turn-mark

• The motorboat must navigate outside the rescue boat or accident boat. However, if there is no safe distance on the outside, the motorboat must navigate according to the judge's instructions.

Violation cases when there are rescue boats or accident boats

• When a motorboat fails to maintain a safe distance from the rescue boat or accident boat
• When a motorboat navigates inside when it should be outside the rescue boat or accident boat near the turn-mark
• Or when a motorboat navigates outside when it should be inside the rescue boat or accident boat
• Any other actions that disrupt the fair and safe conducting of the race

• 
  • In the event of an accident boat, the area where the accident occurs is designated as a danger zone, centred around the centre pole, while the area without an accident boat is considered the contested zone. In the danger area, no position changes are allowed, and proper distance must be maintained while navigating.
• 
  • When entering the danger zone side by side, it is the principle that the inside motorboat leads. However, if the centreline of the front and rear end of the outside motorboat is ahead of the inside motorboat, the outside motorboat is considered the lead motorboat.

Rules for safe racing in the accident area

• In situations where the racing motorboat is put in a disadvantageous situation due to the navigation and rescue operations of the rescue boat, the athlete has no right to dispute. Additionally, if the lead boat is overtaken by others at the accident point, causing a change in placing, the change in order will be recognised. However, strict penalties for the violation will be enforced, and separate sanctions will be applied to the rider in accordance with the rider penalty guidelines.
