In examining the fashion in which a Boom Kicker and or a ridgid vang are attached to the boom and then to the mast, I draw the impression that these devices may have noticeable effect upon the twisting of the boom and therfore the amount of twist that one may apply to a main sail.Basically, a boom kicker has a pin through a slot and a rigid vang has a pin through an eye both rigidly attached to the boom and then ridgidly to the mast. As the boom twists its turning motion would seem to be arrested by these devices, although in the case of a boom kicker with its flexible tubes less so than a ridgid vang.This seems to be true to me as when compared to a normal boom vang which is attached to the boom and mast with bails that should allow full twisting motion of the boom when the vang is loose, but arrest it when the vang it tightened.Thus, is it true that thses devices effect twist in the boom and mainsail? In the case of a ridgid vang it appears that when it is loose, the boom could not twist as much as if it were a normal vang with bails. And for the boom kicker, the normal vang with bails used with it, also would produce less twist when loose than if there were no boom kicker.
