Some discussions don’t work well over the internet and this is one of them. A few random thoughts:
- As
@JTurner asked, yes, a ski with a relatively wider tail is more friendly in that it will be more forgiving vis a vis weight placement —you can still turn from the back seat. If the only part of your ski with shape is the tip, you have to be there all the time to turn. Yes, this same characteristic can lock you into a turn shape and make the ski slower in a course, but this also comes down to skier skill. A good skier will be able to fluidly adjust line, turn placement and turn shape, moving forward to initiate the turn and aft to unwind the ski and accelerate. Yes, there are very few skiers who can do this consistently.
- When you turn, you flex the skis. This builds a lot of power in the ski. We’ll call it potential energy, because the power is built and stored. A good skier will build that potential energy in the upper two thirds of the turn and convert it into kinetic energy in the bottom third to carry them through the transition. The higher in the turn you have max edge angle, the sooner you will be able to convert the energy into motion. A bad skier (most of us) will hold the power-building phase until we are perpendicular to the fall line and release the kinetic energy at the bottom of the turn, effectively pushing us up the hill. If you don’t understand how much potential energy is stored in the system, search “World Cup crashes” in YouTube. When skiers get flipped on their heads in slalom, that’s potential energy being converted to kinetic energy in an uncontrolled direction. It can hurt. A lot.
- I think it was
@mike_m who started a post in ski school about what he learned at a camp in NZ. That gets into how this is accomplished with technique in pretty granular detail. The only thing I would clarify in his post is that it is written from the POV of ski instructors who are trying to control speed with their technique rather than racers who are trying to maximize speed through technique and control it through timing and line placement.
- Understand that timing and tactics are two separate things. Timing is when you start and end a turn and tactics is where you start and end a turn. Both are fluid, however, one mistake I see new racers make often is starting a turn too early. I would define “starting” as when the new edges are engaged with pressure and “early” as before you get to the rise line. Again, this is fluid and early isn’t always bad, but it has implications later in the turn. Also keep in mind that as speeds increase you need to start relatively earlier because you are covering more ground. Tactics is where you begin and end the turn in terms of height. I would say turn placement is a factor of tactics and turn shape is more a factor of timing, but also kind of its own thing. Generally when most coaches say to turn early, really what they mean is turn higher, but delay the turn until the rise line. You can see good examples of this in auto racing, especially on road courses like hill climbs and point to point rally racing. Don’t watch F1, there is too much grip making this hard to see. You’ve heard “in slow, out fast” right? What that means is the back half of the corner is more important than the front half. More specifically, if you go barreling into a corner and come out on a bad line or even worse, have to scrub speed to make the turn, you’re slow. If you control the front half of the corner and exit with speed and good poisiton, you are fast. In ski racing, people tend to put far too much emphasis on being fast into a turn or trying to carry speed into a turn, when what really matters is where are skis are and where they are pointing when you exit the turn. The second part of tactics is extrapolating this several turns down the hill. Let’s say you have a hairpin going into a pitch set with rhythm and then a long flat to the finish. How you exit the hairpin is going to directly affect the speed you carry onto the flat. Better to be conservative, go slow into the pitch and hold your speed onto the flat than to ski the hairpin aggressively, go flying into the pitch and gradually scrub speed and get slightly later each turn, barely holding it together and have no speed when you get to the flat.
- If you want a master class in what this all looks like, watch videos of Ester Ledecka in the PGS at the Olympics. She isn’t technically better on a board than everyone else, she is tactically smarter. There is a lot that happens on skis that can obscure what I’m trying to explain. On a snowboard it is much easier to see.
