A planar board is provided for providing a taut rigging line to spread multiple trolling lines over a wide surface area behind a sport fishing boat. The board is collapsible to provide for storage in gunnel shelves or below deck. First and second parallel, generally planar buoyant boards are provided which are interconnected with a collapsible and adjustable metal frame. First and second parallel channels are disposed on opposing sides of the first and second planar boards. The collapsible metal frame includes a beam which extends between the first and second boards, the ends of the beam including first and second bifurcated bracket structures for slidably engaging the parallel channels disposed on opposing sides of the planar boards. A thumb screw sets the relative positions of the bracket structures and the planar boards. The bracket structures are pivotally mounted to the ends of the beam and a leaf spring is disposed atop the beam. First and second latches are disposed on the ends of the leaf spring, the latches extending through the beam and engaging the pivotable bracket structures disposed on the ends of the beam. The latches thus engage the bracket structures to fix the relative orientation of the planar boards and the beam. The leaf spring need only be lifted to release the latches and render the bifurcated bracket structure pivotable for collapsing the device into a compact package for storage.
