A rudder (40) has a rudder blade (41) mounted on a tiller stock (42) which is pivoted by a tiller (43). The tiller stock (42) is rotatably mounted on a mounting plate (45) which is engagable with a transom on a boat to mount the rudder (40) on the boat. The rudder (40) has a flexible drive fin (47) an inner end of which is clamped between a pair of metal plates (50) attached to the tiller stock (42). A free outer end of the drive fin (47) has a fish tail shape. An inner end of the rudder is rigid to provide steering like a conventional rudder while the outer end flexes back and forth like a fish tail if the tiller is moved back and forth to provide propulsion to drive the boat through the water.
