can one skis be significantly faster

Doesn't everybody? I'll admit I leave the actual car-dinging to the wife
who, in her never-ending quest for efficiency, can't be bothered with
small hammers; impacting major solid objects is her method of choice
when it come to creating auto dimples.

Hi,
had a chance to take my new Fisher RX8 to Snowmass/Loveland Co last week
for 4 days. It is pure pleasure and everything what I read was indeed
true, at least to the my level I can verify it at.

One observation though - I was carving behind my friend and some other
guys following their tracks as precisely as possible. The easiness I
could catch them up and the speed it happened was just astonishing. Also
opposite was true, my friend just could not catch me.

So it posses question: is it due to ski itself, skills or what?

Andy

It is due to several variables:
- ski
- tune on said ski
- skill
- turn shape

Too many variables one significant one since F=ma the heavier skier will
always have better acceleration given the same ski's and tunings, provided
the skiers have equal skill . Also new undamaged ski's well waxed would be
some advantage.

Oversimplification. That depends on the surface roughness of the heavy
vs. light person. See turbulent flow/Reynolds Number.

It's why they put dimples in golf balls.

So *that's* why you pinna heads put duct tape all over your clothes.
It's aerodynamics. Why didn't I think of that before?

I always thought people wax their cars so they'll look nice and shiny,
thus increasing the odds of attracting snowboard chicks and Hooters
girls (where IS Horvath?).

Would your car need to be spherical and rotating for the dimples to
have the desired effect?

The dimples are all natural.

Not if there is no mass change.

Oops.

I saw an ad recently for a computer fan with dimples on the blades.
They claim it reduces noise.

There is also technique involved in making the skis run faster. Skis are
springs and if you use proper technique you can unspring the stored energy
in your skis to help you go faster.

As I ski more & more I find I can keep up with people who were faster than
myself. I used to have to tuck and schuss to gain on them, now I can often
ski down and carve turns next to them.
