Mast Pumping

ispirit2 <ispirit2@...>

Has anyone experienced mast pumping while at the dock? Our '83 Mango
single spreader rig has been experiencing mast pumping while at the
dock causing the entire boat to vibrate and rattle in the mast. The
rigger suggested that we first try to install a staysail wire from
just below the foredeck light at the spreaders to a pad eye just
forward of the windless.

Hope that someone has some information on this issue prior to us
taking action on the riggers suggestion.
