An apparatus for propelling a towed sports participant back and forth one or more times over a surface of land and/or water via a tow line, includes a pair of mutually spaced support structures. An end of the tow line is coupled to a movable carrier mounted to an elevated, reversibly drivable, closed elongated loop having vertically separated upper and lower legs which extend between a pair of mutually-spaced, pulleys which are supported by way of the support structures and mounted for rotation in substantially vertical planes.
