The Snurfer was the predecessor of the snowboard. It was a monoski, ridden like a snowboard, but like a skateboard or surfboard, it had no binding. According to the 1966 patent by inventor Sherman Poppen, it was wider and shorter than a pair of skis, with an anti-skid foot rest. Like a sled, it had a lanyard attached to the front.
