skier's gender and age. Professional ski jumpers have a maximum boat speed of . The ramp height must be between . As a professional jumper approaches the ramp they will zigzag behind the boat in a series of cuts to generate speed and angle. When the jumper hits the ramp they will generally be going over and the load they have generated on the rope can be over . Trick The Trick competition has been described as the most technical of the three classic water skiing events. Trick skiing uses small, oval-shaped or oblong water skis. Beginners generally use two skis while more advanced skiers use one. The shorter, wider Trick ski has a front binding facing forward and a back binding facing at a 45°. It has a smooth bottom that allows it to turn over the surface of the water. According to official 2013 Tournament Rules for 3-event competition in the United States and the Pan-Am Games, skis used in the Tricks event must be a single ski without fins, although molded rails/grooves less than are allowed, as are a foot pad cemented to the ski as a place for the rear foot; in addition, the ski must float with all bindings, fins, etc., installed. The ski's configuration allows the skier to perform both surface and air tricks in quick succession. In a tournament, skiers are given two 20-second runs during which they perform a series of their chosen tricks. In most cases, one pass is for hand tricks, which includes surface turns, rotations over the wake, and flips. The second pass is for toe tricks, which are done by doing wake turns and rotations with only a foot attaching them to the handle; the foot is either in the toehold part of the handle or, professionally, attached to the rope. The toehold part of the handle does not allow the skier to let go of the handle if they lose their balance and fall into the water, therefore a person in the boat is required to release the rope from the boat using a quick release mechanism installed on the ski pylon. A trick cannot be repeated. Each trick has a point value. A panel of five judges assesses which tricks were completed correctly and assigns that predetermined point value to each successfully completed trick. The skier with the most points wins.
