Hydraulic gliding is a kind of one-legged gliding action, with deep blades and low whole body pressure. There are many subdivision types and variations. The most common is that the back inner edge slides backward, the knee of the sliding leg is deeply bent, the other leg is straight, and the ice floes with one hand, and the sliding trajectory is arc.

Water skateboarding can be said to be the representative action of figure skater Yuzuru Hanyu. The reason is that Yusheng can achieve a low posture, a deep blade and a long duration, and does not need to support the water ski on the ice, so it is very beautiful when doing this action.

Although water ballet was not their initiative, it was promoted by shae Lynn Bourne of Canada and Victor Cratz's Canadian ice dancing team in the early 1960s, and their coach Uschi Keszler named him "hydroblade".
