The invention is a pedestal mount for a boat seat including means for locking the seat in selected rotational positions or permitting the seat to swivel in either direction. A cylindrical sleeve attached to the seat rotates within the vertical stanchion. A series of apertures in the sleeve are engaged by a locking pin to stop rotation of the seat in a selected position. A circumferential groove in the sleeve may be engaged by the locking pin, permitting the sleeve and seat to rotate but not be withdrawn from the stanchion. A collar around the top of the stanchion supports means for actuating the locking pin comprising a compression spring urging the pin into contact with the sleeve and a lever handle for selectively withdrawing the pin to a first position outside of the apertures but within the groove so that the seat may rotate but not be withdrawn from the stanchion, and a second position outside of the apertures and the groove so as to enable withdrawal of the sleeve end seat mount completely from the stanchion. Means for locking the stanchion within the supporting base comprise a locking lug extending outwardly near the lower end of the stanchion, which lug engages a locking slot in the receptacle of the base. The lug is urged into the locking position by a vertically disposed hairpin spring lodged within the stanchion. Means located on the stanchion above the base provide for depressing the spring and thereby withdrawing the lug from the locking position. The sleeve is a stepped cylinder, a central portion of which has the same diameter as the support stanchion, enabling the sleeve to be inserted directly into the base support without use of the stanchion.

[ We claim:] [1.] A pedestal seat support for a boat comprising:a seat mount;a vertical stanchion having a walled cylindrical aperture in the upper end adopted to receive a cylindrical sleeve;base plate means for attaching the vertical stanchion to the deck of a boat; and means for attaching the seat mount to the stanchion, comprisingan elongate cylindrical sleeve sized to fit within the cylindrical aperture in the upper end of the stanchion comprising a plurality of locking apertures and a groove encircling the sleeve and communicating with the locking apertures,a locking pin slidingly mounted for movement laterally through the wall of the cylindrical aperture in the stanchion into and out of engagement with the sleeve,spring means for biasing the locking pin into engagement with the sleeve,means for moving the locking pin comprising a lever for selectively withdrawing the pin against the action of the spring to a first position outside the apertures but within the groove to permit rotation of said seat and prevent the seat's removal, and a second position outside the apertures and the groove so that the sleeve and seat mount may be removed from the pedestal.
