The objective of each race is to not only to beat the other racers but also to successfully weave the jet-ski through various buoys. There are two types of buoys: red colored, which are signified by an R on them and must be passed on the right side, and yellow buoys, which are marked with an L and must be passed on the left side. Each time a buoy is correctly passed, a power arrow will light and the jet-ski will gain speed. Up to five arrows can be lit in order to obtain maximum power.
Failure to do either of these will result in a loss of power (though the arrows can be lit again) and missing five buoys over the course of a race will result in disqualification. Leaving the course (either by leaving the area limited by pink buoys or by leaving the water altogether) for more than ten seconds will also result in disqualification.
