Abstract: A mononose structure converts a pair of conventional skis into a twinski. The mononose structure is a tip which includes, a trailing portion of essentially the total width selected for the width of the twinski and a leading portion converging forwardly in a curved nose; a right-hand pocket to hold a conventional ski placed therein and a left-hand pocket to hold a conventional ski placed therein, the two pockets being separated by a central bridge section, and means cooperating with and associated with the mononose and with the pair of conventional skis for clamping the tips of conventional skis rigidly thereto. This provides the forward end of a twinski having an upwardly curved tip and bifurcated tail sections separated by a longitudinal slot. The rear ends of the conventional skis are tied together by tail bridge means at the tails of each of the conventional skis.

Abstract: A monoski is provided herein having an integral mononose section which is preferably made of exceptionally strong material to resist twisting, the integral mononose section including an upwardly curved tip, and bifurcated tail sections separated by a longitudinal slot, with particularly disclosed ratios of widths of the mononose and of the slot. Bindings are provided for securement on each of the tail sections of the monoski adjacent the central waist portion. Bridge means are provided at the tail section adjustably and floatingly holding the tail segments in predetermined spaced apart relation, so that the lateral spacings are predetermined, but yet the tail segments are allowed to move vertically. The ski has extremely good manoeverability, good pivot turnability, controlled turns at substantially all speeds, good support on powder snow and excellent manoeverability in both packed and corn snow. The four edges provide greater control and the interconnected tail section work independently.
