The most popular round type step for the Optimist dinghy. This Optimist maststep has an oval cup, which allows the mast to tilt forward when going downwind. Different mast rakes can easily be repeated using the scale on the base. Separately, a mast step spring lock can be purchased. The stainless steel spring prevents the nut from turning accidentally. There is no need for additional locking nuts anymore.SpecificationMast step type: Round
