Off course wet pullups go higher. In the end, a pullup is conversion from
kinetic energy (speed) to potential energy (altitude). Soaring is all about
trading one of these for the other.
Picture two identical gliders (please, no Discus/Duo Discus (sorry, couldn't
resist)) both at 100 feet, 250 Km/h. Their kinetic energy is derived from
their speed (equal in this setup) and mass. So the heavy one has the most
kinetic energy. -Which one can then obtain the highest potential energy ?

Except that potential energy is proportional to both altitude *and* mass.

IOW, double the mass, and you double the kinetic energy at a given
speed, but you also double the potential energy of the change in
altitude.

Elementary, my dear Watson.

If you think about it a moment, the correct answer is "Elementary, my
dear Galileo" (think dropping balls of different masses, and then
reversing the experiment).



Happy soaring,

OK people, what was the verdict.
I'm sure some logger equipped pullups were made.
Who wins?? Wet or dry.
I still think wet pullups go higher, but I can't prove it.
