Abstract: A frame assembly forming a portion of a rowing accessory is to be mounted within a watercraft, to which frame assembly is attached a seat and oars. The frame assembly comprises first and second frame members each having the general shape of a winged U. First and second wing portions of each frame member extend outwardly from upper ends of the frame members. A track assembly has a beam attached to lower portions of the frame members at spaced apart connection points along the length of the beam. A seat assembly attaches to and slides along the beam. First and second hinge plates each have a first end attached at an outboard end of one wing portion of the first frame member, and a second end attached at an outboard end of one wing portion of the second frame member.
