ABSTRACT:
A telescoping topstay for a rigger that includes a length adjustable tubular member with a diagonally aligned tubular housing attached at its distal end. Attached to one end of the tubular housing is a pin connector that attaches by a bolt to the top end of the oarlock pin. Attached to the proximal end of the tubular member is a transversely aligned pivot connector that connects to a base bracket attached to the sides of the boat hull. The pin connector is able to selectively rotate and lock in a desired position on the tubular housing. The pivot connector is able to axially rotate over the proximal end of the tubular member. During use, the orientations of the pin and the pivot connectors are selectively adjusted so that they match the respective mating surfaces on the oarlock pin and boat hulls.
