    I read in another post that Firefly’s generally have swinging spreaders…

    … is this still the case? and if so, what benefit does allowing the spreaders to swing give?

    … also, is 325mm long x 125-130mm deflection still about right?

    I too would like to hear a reason for having these other than the obvious which is that the spreader ends are less likely to wear a whole in the mainsail.




    Andy, those measurements are in line with Hud’s tuning guide.

    The logic of the swinging spreader is that it’ll swing fwd downwind so the boom / sail can go out further when running..

    However – Now that boats generally have ‘taught’ but not tight shourds for downwind (once the rig is pulled on to reduce jib slack) i’m not 100% convinced that they do actually swing fwd.

    Anyone got any other thoughts?
