Making Carved turns longer on short skis

 Poster: A snowHead
Poster: A snowHead
I spent a few days on a pair of skis about 10 cm shorter than I'm used to (163 cm Head Super Joy 2015) which were pretty fun but I found when carving I usually ended up with shorter turns than I wanted. Not unexpected given the 12.5m radius. It was certainly fun on steeper slopes where the conditions and number of piste users allowed but it got a bit annoying on the flat stuff.

It struck me that I didn't have much in the tool box to deal with it other than flattening the skis out and straight lining it or doing lots of the shorter turns on the fall line. Is it possible to lengthen the turns while keeping the edges in?

Most modern skis respond to how far you tip them over. The more you tip the tighter the turn. To a much lesser extent the amount of pressure also impacts the turn radius. Managing pressure is a skill but if the skis are very tight radius you might be stuck. Maybe try more even distribution of weight and varing the angle.

Apologies if I'm stating the obvious, but here is my understanding.

1. Turn radius (in a carved/mostly carved turn) is down to Edge and Pressure. At any given Edge Angle, more pressure will decrease the radius; and at any given Pressure, increasing the Edge angle will do the same.

2. The slower and more gradually/progressively you add the edge angle, or the Pressure, the longer the radius will be.

3. The point at which you release the turn will determine your speed.

4. SL type skis will feel more twitchy at speed than a GS type ski, especially when trying to go straight.

If I have misled you on anything, I'm sure someone more qualified will be along to put you right.

@Old Fartbag, question, if you have 100% weight on outside ski, how do you increase pressure? Twisted Evil

@Old Fartbag, when you say increase the radius do you perhaps mean increase the tightness of the turn, i.e. decrease the radius....

You Sir are absolutely correct....I can only put it down to a senile moment, or Brainfart, or something... Embarassed

Am now changing it so it makes sense.

You manage the pressure during the turn using your legs and body position. You release the pressure during the transition and apply it during the turn. Nothing too complicated or mysterious about it.

@olderscot, I fear you are missing my point. If you already have all your weight on your ski you physically can't add any more it's an edge angle only issue... Happy

But if you straighten your leg the force on the ski will increase won't it?

There is a limit beyond which it is not possible to cleanly carve the turn and keep increasing the turn radius. For a turny ski like a slalom ski this limit is tighter than something like a GS ski. If you want to open up the turn radius beyond that you need to allow the ski to ski a bit by blending in some rotational steering and less edging.

No. There will be more force.

Imagine you're standing still with your legs bent. The force on the ground will be your body mass times gravity (otherwise known as your body weight). Now press with your legs to move your body upwards. At this point the force on the ground will be your body weight PLUS the additional force you're applying to move (accelerate) your body upwards.

@olderscot, yes, momentarily, but not usefully for shaping a turn.

IMO. There is Passive Pressure and there is Active Pressure.

Passive Pressure is where you do no more than counteract Centrifugal/Centripetal Force.

Active Pressure is where you add to the pressure by pressing on the ski (like on a leg Press Machine in a Gym).

I strongly suspect, as speed gets high and you press down on the ski, it's possible to put more than your actual weight in Kg through that ski....eg. 110% Cool

You can make it last from the start of a turn until the fall line, how else do you expect to make the skis carve above the fall line ?

@under a new name, What don't you understand ? Several posters have described what can be done during a carved turn.

I'm sure you have been given drills to help develop this movement pattern at some point, the "long leg, short leg" one is pretty common.

OTOH, you do seem to like using skis that I would say are too long, so maybe it doesn't work for you.

Thanks guys - it sounds like there are limited options. I was close to 50-50 on the skis and skiing very passively as to minimise pressure while still being on the edges.

I like the point about the progressive edge change and I hadn't considered this properly. I do tend to be less progressive in my edge change which comes from spending a lot of time recently working on raising the performance level of my short turns - I suspect I have subconsciously started moving my weight further inside the line of the skis earlier in my longer turns which will generate more pressure and shorter the radius. I may also be messing up my fore-aft balance a bit on the flat stuff and getting too far forward which I think will engage the front edge of the ski too much and force a shorter radius too. I will defiantly work on making the edge change more progressive in the long turns (this is starting to bring back memories from things instructors have said now...)

A more radical option would be to reduce pressure on the outside ski further by putting more than 50% weight on the inside ski but as far as I understand this would be bad (like crossing the streams for fans of the original ghostbusters film)

Again thanks for the pointers much appreciated.

@Henwc, I have some Atomic SL11s and can do longer turns, provided I go into a different gear and slow down the speed with which I ease the edge over.

Go faster and increase the edge angle, on a flat ski you can only exert your bodyweight, as you turn, you can exert more through centripetal force. How much you can add is a function of speed, edge angle and radius of turn.

@Old Fartbag, I've got the SL12's and it's the same, you just have to imagine you are on GS skis wink Gently tip them onto the edge and and don't let them go too far over and you can get a much longer turn.

@rjs, haha snowHead

My current quiver ranges from 170 to 203 and I can ski them all quite happily thank you.

And I di have a pair of FIS 165 SLs that I could quite happily do super loooong carved turns and super short turns on with a little take off in the middle. But I wore them out Sad

@under a new name, I'm serious, get some 155cm SL skis, you are too light for 165s.

If you are "taking off" in the middle of the turn then you are not managing the pressure on the ski correctly.

Nonsense.

BTW I over powered the wife's 155s.

The taking off is optional and deliberate.
