Sitskis on a Poma?

Sitskis on a Poma?

There is a controversy in our sport about sit skis using drag lifts: T-bars and Poma lifts (Platter lifts). At the NDVWSC in Snowmass the top of the mountain can only be accessed by Poma, but there is a strong rule of “No sit skis on the Poma”. But I spent this week at the CADS National Festival in Sun Peaks BC, and here the sit skis use the Pomas all the time. Continue reading “Sitskis on a Poma?”

The Ins and Outs of the Death Wobble

The Ins and Outs of the Death Wobble

It may be a dramatic term but if you are a tetherer you’ve probably seen a death wobble. It is problem which afflicts quad skis (a.k.a dual ski with pontoons / fixed outriggers) when traveling straight down the hill on flat terrain. The sequence goes something like this:

  1. The ski starts to lose momentum
  2. The ski tips randomly (to the right in this case) and the right pontoon touches the snow.
  3. This causes a braking on the right side of the rig, and the skis twist 15 degrees off the direction of travel.
  4. But the skier’s momentum is still straight forward, now 15 degrees left of where the skis are pointing, so the rig flops over to the left side
  5. Now the left tide pontoon touches down on the snow
  6. This causes a braking on the left side of the rig and the skis twist to point 15 degrees left of the directing of travel.
  7. Now the ski flops to the right and the whole cycle continues, etc.

Going off Leash

Going off Leash

Skiing is cancelled today due to rain & warm temperatures, so time for a blog. We rarely use the bunny hill with sit skis at the Edelweiss program, it is too full of small children on the days our program runs. So, our sit skier progression is mainly about running a green trial top to bottom repeatedly on tethers. The first run is 99% tetherer controlled with the skier as a passenger, then slowly responsibility for speed control, turn initiation and route planning are transferred to the sit skier.

Slip Sliding Away

Slip Sliding Away

Last year at the American Winter Sports Clinic I had a class with an unusual student. He rode a monoski without tethers and could turn and stop independently perfectly well on green slopes. But he ran into problems when we moved to a steeper blue slope. With each turn he picked up speed rather than lost it. He could bleed off speed by traversing the whole width of the hill before turning again, but not quite enough. As a result, his progress down the hill looked like demented pendulum, crossing back and forth across the run at every increasing speed until the inevitable bail out.

Thumbing, just how evil is it?

Thumbing, just how evil is it?

First let me define “Thumbing”. Thumbing is controlling a sit ski by standing behind it and holding on to the back of the seat (also known as the “Bucket”). It’s called Thumbing because a common grip is to place the hands palm forward, with the fingers outside the bucket and the thumbs inside. These days a growing number of sit skis have a handle attached, so the natural grip is more like pushing a shopping trolley, but I still call it thumbing.

Nobody objects to thumbing to push the sit ski across flat ground, such as from the chalet to the chair lift. It becomes more controversial when you mean Thumbing a sit ski to control it while descending hill. In my home program it’s frowned on, A sit skier who is being thumbed isn’t controlling, or even contributing to, their direction or balance. So they aren’t learning anything, they should be on tethers instead. Continue reading “Thumbing, just how evil is it?”

Sit Skiing: One Discipline or Two?

Sit Skiing: One Discipline or Two?

I’m old enough to remember when the term “Monoski” meant something like the above.

But these days it usually means a sitski mounted on a single ski, the alternative term is “Bi-ski” for a sitski mounted on 2 skis. At the Edelweiss program we tend to think of a monoski like a sports car, and the bi-ski like the family station wagon (I guess that’s a minivan these days).
