Abstract: The mast displacement system is mounted on the hull of a sailboat and holds the mast in a movable, upstanding relationship on the hull. A rectilinear mast guide track is rigidly mounted to the hull of a sailboat and extends in an approximately horizontal attitude and transverse to the longitudinal centerline of the hull, and a mast pedestal includes track engaging guides which engage the mast guide track so that the pedestal is movable along the length of the mast guide track. The mast of the sailboat is held by the mast pedestal in an upstanding attitude, and a plurality of mast stabilizer arms extend laterally from the mast pedestal and move in unison with the mast pedestal, with the forwardly extending one of the stabilizer arms being slidably connected to a second rectilinear guide track mounted to the hull of the boat.
