That's part of the fun! For smaller ones like the Moth or Waszp anyway. Less fun and quite expensive in an AC75...
The dynamics of a sailing boat are far more complex than a motor boat. The drive comes from halfway up a huge lever (the mast) over the foils and its position relative to the forces produced by the foils is constantly and suddenly changing both on its own due to gusts and shifts in the wind and also caused by the sailor's inputs.
A motor boat pretty much only has to deal with going up and down over the waves.
It's like the difference between solving a linear equation and a higher order differential equation.
