Surfskating
Surfskating, or surf skateboarding, is a form of skateboarding that replicates the experience of surfing on dry land. A surfskate system is distinguished from a traditional skateboard system by the utilization of two different trucks, front and back, with specific functions and geometries that, together, yield thrust, just like a surfboard.
Surfskates, or surf skateboards, were invented by surfers who wanted a way to surf on days with no waves. Surfskates are often used by surfers to train for surfing.
Surfskating is differentiated from carveboarding, which refers to riding a Carveboard specifically, which are no longer in production. Since Carveboards use the same trucks on front and rear, they do not generate thrust in the same way that surfskates do.
