What does "stable skiing" mean? :) Can you explain please?

Question

I found out the longer the skis, the stable they are. But I don't understand that :( Please explain that to me in a couple of words :))

Answer 1

There are 2 types of instability, both of which become more pronounced the faster you go:

The first is vibration of the skis. the front and back of the skis bounce up and down (wobble vertically). When that happens less of the ski is in contact with the snow. The stiffer and longer the ski, the less problem there is. However these skis are harder for less experienced skiers. It also explains why Downhill racers (speeds over 100kph) use the longest skis. Have a close look at some downhill races on Youtube and you will see the vibration in the skis.

The second type is most noticable when sking in a straight line without "edging" the skis, especially when crossing other tracks or ruts in the snow. Then the skis can wobble left/right instead of tracking dead ahead. At speed that can be disconcerting. This can be pronounced on skis with deep sidecuts, i.e. modern carving skis with wide shovels and tails and narrow waists - small turning radii.

So in summary, longer, stiffer skis are more stable but are less forgiving. They are less tolerant of the skier's mistakes. It's a trade off.

Answer 2

The ability to balance is made easier. It also means that you will have less "chattering" of the skis.

Answer 3

Try this, balance a pencil on your hand, without moving. Now hold it upright between 2 fingers in the same position.  The first way the pencil wants to tip every once in a while and fall over. The second way the pencil stays in one place and is very stable.

  Basically the more stable, the less it will tip over, with skiis the tipping is front to back.
