Abstract: An offset stanchion for a fishing boat seat has upright support portion extending through the deck floor of the boat. An offset support portion is rigidly connected to the upper end of the upright support portion above the deck floor, the lower end of the upright support portion being supported and rotatably mounted in a bearing mounted on the hull or rail for securing the keel of the boat. In an alternate embodiment, the upright support portion is supported by a bearing mounted in a can recessed below the deck floor. A seat support portion is rigidly connected to the upper end of the upright support portion and is parallel thereto, so that a seat mounted thereon can be moved to any position about a central axis of the upright support portion on a circle having a radius equal to the spacing between the central and the seat axes.
