<p>The water skis allow practice on water without a towing boat. It has two independent skis of variable lifting capacity (1) and an engine driven water jet drive (6) fixed to a pivoted support (4) connecting the two skis. The skis can turn about 60 degs horizontally and 50 degs around the support fixing. The skis, on water, have a variable lift to give, at rest or low speed, a floatability greater than normally used. The user stands on non skid fast boards (2) and can create a counterweight to compensate for tilting of the skis.</p> |
