A standing support assembly for a boat deck to assist boaters with physical limitations in maneuvering around a bass boat. The standing support assembly includes a rigid, elongated stanchion member that is hingedly attached to one end of a rigid, planar attachment plate. An anchor post extends downwardly from the other end of the attachment plate and allows the standing support assembly to be locked into a base plate on a bass boat. Through its hinged attachment, the stanchion member is able to move between a deployed position in which it is orthogonal to the attachment plate and a storage position in which it is parallel and adjacent to the attachment plate. When in the deployed position, a user can hold the stanchion member for added support while moving around on the boat.
