Abstract: The present invention is a boat seat support. A first track is mounted to the floor, and has a lifted edge spaced above the floor which defines a first channel. A second track is mounted to the floor opposably spaced-apart from the first track, and defines a second channel. A slidable base slides longitudinally within the first and second channels of the first and second tracks. A pedestal receiver attaches to the slidable base and is adapted to receive a support pedestal. A lock is disposed on the slidable base proximate one of the first and second tracks, and is adapted to selectively inhibit slidable movement of the base by engaging one of the tracks. Disengaging the lock allows longitudinal positioning of the boat seat support along the tracks, and engaging the lock fixes the longitudinal position of the boat seat along the tracks.
