A ski includes a base plate ( 2 ) and a raised, central platform ( 3 ). A front supplemental element ( 6 a) is removably attached to a front end of the platform and has a pair of longitudinal arms ( 60, 61 ) extending forward along a top surface of the base plate. Similarly, a rear supplemental element ( 6 b) is removably attached to the rear of the platform and has a pair of longitudinal arms ( 62, 63 ) which extend slidably along the top surface of the base plate. The supplemental elements are removably attached using a tongue ( 8 a , 8 b) and slot ( 9 a , 9 b) arrangement and a latch ( 10, 11, 100 ). A visual indicator ( 11, 12; 15, 16 ) indicates when the supplemental element is properly connected. The supplemental elements include a basic structure ( 600 ) with supplemental reinforcing elements ( 601 ) removably attached to the undersides of the longitudinal arms. By changing the reinforcing elements ( 601 ) and changing among supplemental elements with arms of different length and characteristics, the behavior of a ski can be quickly modified to match a user's taste, the terrain, and skiing conditions.
