@nathan_bogan thank you for the vote of confidence--I am certain that when looked at from an objective standpoint followed by empirical investigation, this proposal is a better solution than current parameters.
I would prefer this discussion to remain in this thread for now, to diffuse any potential confusion relating to belief in need for rope length changes. Reduction in the increments is the wrong path to go down. I could elaborate but would rather focus on the benefits of widening the course. And keep in mind that the proposed new dimensions would demand, in practicality, a similar ski path that the existing course demanded in the 70's and early 80's--before modern (small) buoys. Yes, small buoys are a sensible progression in the event, for safety, precision and consistency, but small buoys have altered the ski path requirements in a negative way.
Today, 41 (10.25m) is the pass to run. When a top skier runs 41, they will be at or very near the pinnacle for the event. And though tournaments occur where more than one skier gets through 41, it is fact that most do not. So let's define 41 as the PTR (pass to run; aka "the cat's meow").
10.25m is 1.25 m shorter than the 11.5m width (from centerline) of the course--that's 4'1.2" short of the width of the course! It is quite clear that any consistency here, in addition to exceptional skier ability, will depend upon skier height, and favorable boat path (by favorable, I mean free of negative deviation). Let's define the difference between the course width from centerline and the rope length as the rope delta (RD). SO, the current PTR has an RD (rope delta) of 1.25m.
Current longitudinal dimensions between boat guides/turn buoys is 41m. If this dimension is maintained, it is fair to say that by increasing the turn ball width from 11.5m to 11.75m or 12m, running the course with the same RD will be more difficult (if this is questioned, simply map the current course and the widened course, and examine the angular requirements). As the wider course makes it more difficult to run the same RD as the current course, we can logically deduce that the PTR of the wider course will ultimately have a lower RD than the current course...
As a lower RD means a reduced value factor for both height and favorable boat path, the wider course is favorable for both shorter skiers (as compared to the current course), and also less dependent upon driving. These are two significant impairments to the current model at the elite level. An ancillary benefit of the wider course model will be the superior properties of longer rope lengths for skier longevity. Anecdotally, the wider course model, as mentioned earlier, is somewhat a "return" to the original intentions of slalom skiing, in terms of the ski path requirements (due to modern buoy size). And today's technology in boats and skis has already made things substantially more efficient/easier.
And so I'll leave with you... what will the RD of the PTR be on an 11.75m course? How about a 12m course?
