What is "shaping phase"?

post #1 of 9
Thread Starter 
What does the term shaping phase refer to? The term implies to me that it's not all of the turn. Why isn't it all of the turn? Or is it sometimes?
I'm leaning towards that shaping phase is roughly equal to high C, but then I don't see the reason for the term.
If it's high C, is the reason behind it that it's a non carved high C?

Hey Carl.

 

Again I'll give the basic PSIA definition, then let the more advanced instructors detail.

 

Three phases of a turn.  Initiation, Shaping and Finish.

 

Breaking it up that way should be fairly self-explanatory.   It has nothing to do with carved or non-carved.  It's temporal, the middle of the turn.

Not really.  I usually start backing off the edge angles and generally preparing for the next turn shortly after the apex of the current turn.  I'm still worried about the shape of the current turn (or at least still aiming for a pre-determined point at which I'm going to change edges).  So have I started initiating the next turn, am I still shaping the current turn, or am I finishing the current turn?

Wow, guys it so much simpler than what you're trying to make it. Said another way the shaping phase is commonly identified as the third of the turn where the apex of the turn will occur. That's where the highest edge angle and muscular effort will occur. In PSIA circles the middle third of a round medium radius turn is used as a reference maneuver to keep the confusion to a minimum. That being said we can certainly move that apex around, either earlier, or later. But here's the thing. The start, middle and end of the turn still exist. We may abbreviate that initiation phase (start) to move the apex higher in the turn, or we can lengthen the start to delay the apex to a point later in the turn but that also includes abbreviating the finishing phase (end) of the turn. In racing circles that skill level corresponds with the ability to successfully ski a more direct line. In the rec world where we ski much slower, the skill level and the need to move the apex around would correspond with expert tree skiers who like their racers cousins have their line defined by obstacles. Beyond that, on a wide open slope, the ability to do that is largely academic since their line choices are not set for them.

High C?  What's that?  Some noxious drink, similar to kool aid?  Imagine the "shape" you'd be in if you drank a lot of that stuff.

 

Personally, I don't use the "shaping" term, as it just doesn't seem to me to be an accurate descriptor of only a portion of a turn, because in reality I'm actively and purposely shaping my turn from the time I lay my skis on edge, to the time I roll them off edge.  IE;  If I soften the rate of change of my radius through the top of the turn, and intensify it through the bottom half, or vise versa, the entire time period I'm on edge is involved in the shaping process.  

 

So, I'll leave it to those who actually use the term to describe it for you.  I have no issues with others using it, it just doesn't work for me.  The guys above seem to have done quite well explaining their usage of it for you.

Speaking of the High C, I was reading last week that Harald Harb snapped his Achilles tendon recently while skiing.

Nah, it's a part of the turn.
