I was perusing social media a couple days ago when I came across a post by Ron Goodman about experimenting with different length jump ropes. This topic magnetically drew me in, and I thought it might gain a little more traction/commentary on BOS. See original posting below:
***************************************************************************************************************************************
Ron Goodman : Had a rip with an 85' rope today...just added 10' of Dyneema to my mainline. Felt pretty good...might be a bit long. Will try 80' tomorrow, then 1' increments. This is a conversation that needs to happen. Why is the jump rope 75'? Seems everyone wants them maxed out on length...which suggests they're to short. Why not 76'? Or 82'? Time to test and find optimum for each speed.
Micah Ping : Why even regulate the length of the rope at all?
@Rdodd : Good call !
Scott Snape : I agree as you can run the boat wherever you want. One consideration is safety. Some of the sites we ski at you come very close to objects on a 75 foot rope. 80 plus might have you colliding with those objects. Charleston is a prime example. When you turn for the jump you are in less than 2 foot of water. 5 more feet of rope and you will be turning in sand.
I said I would never jump there again as the shallow water lifts the tails ( especially the right ski) driving the tip in which makes it almost impossible to get you ski around. Last time I was there I got my driver to run narrow and when he felt me set my skis move out to split. It worked but not something I want to repeat.
Ron Goodman : It's a good point Scott. My thinking is that it's a self correcting problem however. There are sites I won't jump at no matter what rope is used. Haha!
I like Micah's point...why measure at all? If we can already adjust boat path it only makes sense to mess with ropes as well. We already use our own anyway so this is a tiny step. Each skier could figure it out for themselves, no different than how much spectra to use. Maybe Jrs or slower speeds would like a shorter rope??? Ploppers just starting out...shorter? Food for thought. Gotta try...
I can say 85' at 35mph felt to long. Just an opinion of course. Boat ran right up next to 60's and I wanted it wider. What I did like was the rhythm out of the turn and comfort it gave for finishing turn. Bit different off the ramp but I think that's boat path.
I'll try 80'. My gut feeling is it'll be better. We'll see. I'm gonna try though...and report back.
Point of all this is two things. First is to make jump better/safer, and second to make tournaments easier to run from a tech standpoint.
@Ham_Wallace : I have always liked my 83"!
@The_Krista : We get to pick our preferred length in slalom and trick for optimal performance ...just saying :smile:
Alex King : Trick yes, slalom no? You get to choose where you start but not where you finish! Haha but good discussion!
@The_Krista : Haha you get to choose what is best for you to be able to ski your top performance...(kinda)..work with me here Alex! Also...the length of the rope in slalom is an integral part of comparing scores so some uniform system of measurement is necessary but still your personal preference for optimal performance is your initial choice ... The length of the rope is not used in calculating any results for trick or jump... :smile:
Ron Goodman : My thoughts exactly Krista. Jump is scored on distance alone. The 75' rope length was mandated so long ago that the logic is irrelevant in today's jump event. Skis were wood, short, and unstable. Bindings were basically flip flops bolted to the wood planks. Slings didn't exist. Ramps were wood, short, and dangerous by today's standards. Boats...hand driven twin rigs.
It's time we take a serious look at the ropes and the length we use.
I'm leaning toward total skier choice for both materials and length. I'm a Guinea pig...and will report my thoughts as they develop over the next few months. I encourage others to do the same.
Jeff Rush : Would longer or shorter ropes affect how the switch engagement would need to be calibrated? Would ZO need to add the 1,2,3 principle, like in slalom and trick, to the jump letters to adjust for rope length? 1= <75', 2=75', 3=>75'? Why can't the switch be skier supplied option to adjust to their spec'd tension instead of the standard 120 lbs?
Ron Goodman : No. Switch works the same. Can't tell any difference.
