"Classe 10"

On the boat I described earlier a wand (like on a Rave or Moth) would be used to keep the boat at a more or less precise angle of heel when flying the main hull. That makes it easier to design the rudder and daggerbaord for the correct upwind area. Using this system also means that in light air both the rudder and daggerboard will have to be partially retracted to reduce wetted surface. But with so much SA and so little weight she'll be flying the main hull pretty early-6-8mph....
