I've noticed a slight inconsistency or lack of clarity in the rules about boat path - at least to me.
Rule 10.07 B says this:
Where end course is available, the towboat pylon shall not deviate by more than 20cm (7.87in) from the course centerline. For instances where end course video is not available, the boat shall follow a straight path as close to the centerline of the course as possible.
This rule seems to say that excessive deviation either way (to the advantage or disadvantage of the skier) is not allowed and is, rightfully so, a possible reride justification. It does not say where the deviations are measured or considered for tolerance and/or reride consideration.
Rule 14.04 says this:
Maximum deviation of the boat on approach to each buoy/gate is 20 cm (8”) toward the side of the skier buoy.
The table in 14.04 is clear about the allowed cumulative deviation for each buoy point attained in the two passes that are considered for confirming the record.
So, I have two questions:
1. If the boat path is off center away from the skier side of the buoy (i.e., a disadvantage to the skier) at the point of measurement, is that deviation ignored or added to the cumulative deviation calculated for a record pass? It seems odd to count a deviation to their disadvantage against them, especially if they are in contention for the record. Rule 14.04 seems to say only the deviation to the advantage of the skier is counted.
2. What is the point or zone of measurement actually considered for a record pass and what happens if the boat should deviate more than the allotted amount outside of that point or zone? For example, the boat is within tolerance at the point/zone of measurement, but is out of tolerance at some other point in the course before the driver corrects it to reach the measurement zone.
It's not like I will ever be in a position to pull a record, but I want to drive like I am every time.
If there is any video or narrative (detailing when/how the measurement is captured) on a record pass being measured for deviation, that would be interesting to see.
