steering runner

The stern or steering runner is worked by a tiller or wheel.

Modern iceboats designs are generally supported by three skate blades called "runners" supporting a triangular or cross-shaped frame with the steering runner in front.

The first iceboats were adaptations of regular sailing boats, with a wooden plank fastened cross-wise at the front having a fixed runner at each end, and a steering runner attached to the bottom of the rudder at the stern (back).
