Abstract
A boat seat is rotatably supported on a tubular deck-mounted support post or column by a yoke having an annular extension engaging said tubular support. A locking plate having ridges or teeth for engaging slots on the exterior of the tubular support is mounted on the yoke and is selectively movable into locking engagement with said slots by a lever arm to positively prevent rotation of the boat seat. A spring biases the locking plate out of locking engagement when the lever arm is moved to the unlock position.
