Current 11.02

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.

Proposed 11.02

In the jumping event, it is the responsibility of the driver to set the speed control to the base speed and cut letter selected by the skier (see Rule 13.04). If the time does not meet the criteria in the 52m segment, he will adjust the base speed. If the time does not meet the criteria in the 30m segment or the 41m segment, he will adjust the selected cut letter. 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.

13.04: Boat Timing (2004)

The boat shall be timed in the jump course between buoys 15ST-19ST and 15BT- 19BT (52m - 1st segment), 15BT-19BT and 15MT- 19MT (30m - 2nd segment) and between 15MT-19MT and 15ET-19ET (41m - 3rd segment) in order to maintain the tolerances listed in the chart below:

Times must be recorded to the 100th of a second.

The times driven should be as close to the recommended times as possible. This will be monitored by the Chief Judge.

In the case where a skier refuses the ramp or falls on the approach to the ramp, the maximum speed tolerance allowable in the 2nd segment shall be increased by .03 seconds. This may be done by either subtracting .03 seconds from the maximum speed tolerance or by adding .03 seconds to the time recorded.

The time allowed in the 2nd segment is conditional on the time measured in the 1st segment as shown in the following charts.

The 3rd segment times only apply when the speed is at the maximum for the division. After the 3rd segment, the speed control algorithm will be to set the speed to the base selected speed.

When the speed is below the maximum for the division, the third segment will not be used with the exception that it may not exceed the maximum speed time for the event division. (Please note that if this happens, it is likely that the speed control is not working according to the intended algorithm and the manufacturer and the TC Chairman should be notified). The manufacturer's algorithm in the less than maximum speed case is to set the mechanism to the base speed setting (no overspeeding and no underspeeding) in the 3rd segment.

At the skier's option, the mode may be set to either normal, meaning the case where the speed control just returns to the base speed setting in the third segment, or to the new settings where the boat is programmed to meet the times in the above chart.

The rules governing skier letter or distance selection apply for this mode as well.

13.04: Boat Timing (2004)

The boat shall be timed in the jump course between buoys 15ST-19ST and 15MT- 19MT (82m) and between 15MT-19MT and 15ET-19ET (41m) in order to maintain the following tolerances:

Times must be recorded to the 100th of a second.

The times driven should be as close to the actual times as possible. This will be monitored by the Chief Judge.

In the case where a skier refuses the ramp or falls on the approach to the ramp, the maximum speed tolerance allowable shall be increased by .05 seconds. This may be done by either subtracting .05 seconds from the maximum speed tolerance or by adding .05 seconds to the time recorded.

The 2nd segment times only apply when the speed is at the maximum for the division. After the 2nd segment, the speed control algorithm will be to set the speed to the base selected speed.

When the speed is below the maximum for the division, the second segment will not be used with the exception that it may not exceed the maximum speed time for the event division. (Please note that if this happens, it is likely that the speed control is not working according to the intended algorithm and the manufacturer and the TC Chairman should be notified). The manufacturer's algorithm in the less than maximum speed case is to set the mechanism to the base speed setting (no overspeeding and no underspeeding) in the 2nd segment.

At the skier's option, the mode may be set to either normal, meaning the case where the speed control just returns to the base speed setting in the second segment, or to the new settings where the boat is programmed to meet the times in the above chart.

The rules governing skier letter or distance selection apply for this mode as well.

13.15: Timing of the Boat (2007)

The boat judge shall observe the accuracy of the boat path and verify its speed by checking the speed measuring devices.  Alternatively the boat may be timed on shore by other automatic timing devices approved by the Tournament Council. In the event that the time is taken on shore, however, it must be communicated to the boat by radio immediately after each pass. An approved automatic timing device must be used in the World Championship Tournament.

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. (Back-up in boat?)

The times from all segments of the jump timing course shall be recorded and a reride shall be granted under the following conditions:

Generally speaking, if any time is too fast, then a reride for the skier is mandatory. If no times are too fast, but if any time is too slow, then a reride for the skier is optional. On a pass or a fall before the ramp, the 3rd segment time will not be used.  All situations are detailed in the timing chart below.

If the second or third 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.  When there is a fast 2nd or 3rd segment, the boat judge shall signal the skier by crossing his arms at 90 degrees (in the sign of an "X") to show that the skier may have a potential reride. (2007)

When the speed is above the maximum allowable for the pass, a rerun is mandatory. If the speed is below the minimum allowable for the pass, the contestant will decide whether or not he wishes a rerun on that pass, but shall not be scored less than the distance obtained on the pass leading to the reride.

If the speed chosen is below the maximum, and the time is out of tolerance, the contestant shall have the option of a reride as long as the maximum speed tolerance was not exceeded, in which case the reride is mandatory.

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.
