skiing/snowboarding is one of the sports where the skill difference between men and female athletes is most apparent. many other competitive sports are much closer in terms of relative skill, gymnastics for example, but largely i blame the discrepancy on the lack of historical development. given more time and with a better coaching infrastructure, you will see a convergence of skill level. but even in well developed sports, men generally have a physical advantage just because of the differences in muscle development. i would think that females with a lower center of gravity would have advantages in certain areas though.
nonetheless, i would much like to see more pretty female skiers on the slopes
