Abstract: A ski instructional apparatus and method for teaching young children that allows for dry land training of a student on skis. The apparatus includes a pole that the student straddles. The pole has a cross piece that extends behind the students legs and beneath the buttocks and handlebars for the student to hold onto. Pulling the pole forward causes the cross piece to push the student from behind so little or none of the student's arm strength is needed to pull the student on skis along a dry surface. The tips of the skis are connected by a tether and a line attached to the tether is connected to the pole. The arrangement allows the instructor to move the student forward and, at the same time, to move the ski tips one towards the other or allow the tips to move apart by respectively raising or lowering the pole.

Abstract: As an aid for a novice skier, a close fitting fabric glove confines the forward portion of a pair of water-skis. The glove both prevents excessive lateral separation of the skis and maintains a desirable minimum separation--both features greatly assisting a novice, for example, in "getting up" from a deep water start and in his stability when waterborne. The greater planing area of the glove, compared with the ski portions it covers, and its buoyancy (from air entrapment), both help the skier to "get up" more quickly. Flexibility of the fabric of the glove permits substantially normal relative tipping and pitching of the skis for control purposes. The glove is secured to the skis by snap fasteners.

Abstract: Two pivoting parts (8a, 8b) each mounted on one of the skis (1, 2) forming a pair are arranged so that each of them cooperates with two retaining parts (7a, 7b) each fixed on one of the skis. When each pivoting part (8a, 8b) is fixed via its free end to the retaining part (7a, 7b) of the same ski, the skis are separate (FIG. 1), whereas when these pivoting parts (8a, 8b) are rotated through 90.degree. and are fixed via their free end to the retaining part (7a, 7b) of the other ski, the two skis (1, 2) are locked in position relative to each other (FIG. 2). These parts allow the skier to change from conventional skiing to monoskiing and vice versa, by operating the pivoting parts and without having to remove his skis.
