Baller Monkstr6100 Posted August 19, 2013 Baller Share Posted August 19, 2013 Not sure why it really matters to me, but been really wondering how much force/weight is on the line/pylon when a skier is cutting hard? Just something that has been on my mind recently. At work I have access to dynamometer but I don't think they would be thrilled with my reasoning to take it home and hook it on my rope. Thanks in advance experts, Zach J. Link to comment Share on other sites More sharing options...
Baller ForrestGump Posted August 19, 2013 Baller Share Posted August 19, 2013 Marcus brown and Terry Winter had video of them with a strain gauge. It was 600 lbs of pressure at 38 off or something like that. Link to comment Share on other sites More sharing options...
Baller mwetskier Posted August 19, 2013 Baller Share Posted August 19, 2013 terry winter was actually pulling more then 600 lbs but the interesting footage was when they compared both skiers at the same time and seeing the difference in loads and where they happened in the course.

Baller ozski Posted August 19, 2013 Baller Share Posted August 19, 2013 6 pulls per pass @ 600lbs in 16 seconds = a sheet load of weight, no wonder it takes a toll on your body.. Link to comment Share on other sites More sharing options...
Baller 6balls Posted August 19, 2013 Baller Share Posted August 19, 2013 That's probably a clean pass, too. A scramble with a slam or two can produce short, tremendous, rope breaking loads (not to mention it hurts my back...not that I know anything about this!)

Baller A_B Posted August 19, 2013 Baller Share Posted August 19, 2013 I thought Mapple hooked up to LISA years ago in Spray magazine was near 800 at peak behind boat. I am probably over 600 coming out of the water. Link to comment Share on other sites More sharing options...
Baller ktm300 Posted August 19, 2013 Baller Share Posted August 19, 2013 Highest load is within a ski length inside the buoy line. Lightest load is centerline out. Link to comment Share on other sites More sharing options...
Gold Member Than_Bogan Posted August 19, 2013 Gold Member Share Posted August 19, 2013 For shortline skiers, 3x body weight is a passable estimate. I like to think about it that way because that means every pound of weight dropped is 3 pounds I don't have to hold. Insane shortline (39, 41) is gonna be a little more and -- as 6balls notes -- form breaks may lead to it being much higher. Although I have none of my own data or analysis of that case, the nearly 5x body weight implied by the strain gauges mentioned above is pretty believable.

Baller A_B Posted August 19, 2013 Baller Share Posted August 19, 2013 LISA might even have been before PP, so hand throttle. The theory back then was to peak load behind the boat, not pre load into the first wake. Mapple was compared to some decent 35 into 38 skiers, and his peak load was plotted right behind the boat, and virtually no difference onside to offside. The mortals had much more variation in peak load between onside and offside, and as well same side to same side, and longer and later. Mapple's chart slope was pretty steep and the mortals were much more flatter. I will repeat, the mortals were good skiers! It would be very interesting to see what Mapple does today behind ZO.
