Rule 12 - BOAT SPEEDS / TOLERANCES

12.1: Boat Speeds

All boat speeds are speeds over the bottom, compensated in all cases where a current exists.

12.2: Tolerances

12.2.1

All speeds in Slalom and Tricks shall be accurate to plus or minus one km/h. For a speed to be considered accurate, the maximum and minimum speeds recorded in the course, as noted by the official in the boat, must be within the tolerances allowed.

12.2.2

In Slalom, the average speed through the course must fall within the tolerance allowed (15.6). The speed may vary a maximum of 1 km/h for a distance before entering the competition course and shall be maintained until the skier is out of the course. If the tolerance was exceeded and in the opinion of the official in the boat, the speed variation was advantageous to the skier, a reride will be mandatory. The skier will have the option of a reride if it was considered to have been disadvantageous.

12.2.3

In the Jumping event, the average speed through the timed portions of the course must fall within the tolerances allowed (14.4.2). If, in the opinion of the boat judge, the speed before or after the timing course was disadvantageous to a skier, he/she will be given the option to reride on the pass affected.

12.2.4

Tolerances are intended to allow for unavoidable human error and it is intended that the drivers attempt to drive to the actual times. The Chief of Competition shall undertake the responsibility of determining if the drivers are observing this general principle (See also Rule 10.5).

12.3: Timing Devices

Timing devices in all events shall be accurate to at least 5 parts in 10,000 (.01 sec. per 20 sec.)
