Must be a way to control the height rather than crudely pulling boards up and down. As Wouter said above, the moths have this semi-automated with the wand allowing you to control your height. The manual part is setting what level of ride height you want, and you regularly change this based on your speed and wave/wind conditions. Moving weight back/forward was what the mothies did initially when foiling started, but now don't move at all as the systems work.

And this new 20 better be quicker than the old 20! In 15 knots of breeze and flat water on the weekend, it didn't stand a chance against the moth downhill. Motored past it when they thought they were doing full noise...
