The rotation inducer is part of the mast base. There is an arm on each side of the base connected to the opposite side of the from cross beam via a 3:1.



The neatest part of the system is the outhaul is connected to the rotation limiter. Blow the outhaul and you blow the rotation limiter. When you pull the outhaul back out, you reset the the rotation to it's previous position. When you have to pinch, ease the outhaul/rotator and it really powers up.
