A boat seat stabilizing apparatus is provided which includes a support column having a base fixedly attachable to the deck of a boat for supporting other connected parts of the device; a first support arm having a front portion pivotally attached to the support column in a manner to remain about horizontal; a second support arm having an upper portion pivotally attached to the first support arm in a manner to remain about vertical, and further including a chair mounting post to which a boat seat chosen by the operator is attachable; a pitch guard mechanism operatively connected to the first support arm and the support column to substantially prevent foreign objects from entering the area of attachment between the first support arm and the support column; and a roll guard mechanism operatively connected to the second support arm and the first support arm to substantially prevent foreign objects from entering the area of attachment between the second support arm and the first support arm. A position locking device is also provided which allows the operator to lock the apparatus in a fixed position so that the invention may also be used as any other non-stabilized boat seat should sea conditions warrant.
