Any examples, please? Especially easy ones like longer tillers and vane arms.
That is one kind of servo. Others are possible. It is a force multiplier.Cheers,PeterSent: Wednesday, July 13, 2011 5:47 PMSubject: [harryproa] Re: Wind vane vs compass self steering
my understanding is that the servo is just a foil in the water whose AOA is adjusted by the wind vane. changing the AOA causes it to swing sideways about a horizontal axis. this movement is then coupled to the rudder(s). so yes, it needs to be shunted, but no, it does not need to be trailing at the back of the boat. agree?
i think the optimal place for the wind vane would be on the ww hull away from the sail turbulence and in the fore-aft center of the boat. the servo would be best in the lw hull to insure it was always in the water if the ww hull flew, and again in the fore-aft center. not ideal to have to connect the two at such a distance, but you've already got other lines traversing the tramp, so what's one more.
