Abstract: A new ski disk for supporting a user while being towed behind a boat. The inventive device includes a circular disk member having a central planar portion and an upturned outer edge portion. A non-slip pad is attached to the top of the central portion to provide cushioning to the user. A track member is secured to the central portion and is embedded within the non-slip pad so that it does not extend beyond the top of the pad. A pair of foot holds are connected to the track member in a manner permitting adjustment of the foot holds relative to the track member, or else the foot holds can be removed when they are not to be used.
