This obstacle is a combination of the Unstable Bridge and the Hourglass Drop, consisted of two boards. The first one is an uneven S-board (similar from the board from the Hourglass Drop), and the second one is an an uneven pyramid board.
Competitors must hold onto to both sides of the boards and maintain their balance while crossing. While crossing the first board, competitors must use momentum to reach the second board. On the second board, competitors must reach the other side while keeping both ends even.
In its first appearance, this obstacle took out half of the competitors who attempted this obstacle, including Neil Craver, Adam Rayl, Nicholas Coolridge, Jessie Graff, and most notably, Joe Moravsky (making it the first time he fell on Stage Two).
A special rule was implemented in this obstacle, in which competitors must make a transition to the second board, before being able to make a dismount (as competitors could have the ability to skip the second board entirely by dismounting from the first board). This rule came into play, when Flip Rodriguez dismounted the obstacle early by skipping the second board entirely, resulting a disqualification. Drew Drechsel almost got disqualified on this obstacle for dismounting the obstacle early. Fortunately, he was able to grab the second board, successfully landed the platform, and completed the obstacle.
The Wave Runner returned on American Ninja Warrior 9, once again as the third obstacle in Stage Two, with a similar specification from last season, albeit the boards being larger. Only 7 out of 36 competitors who attempted it, failed on this obstacle (including Brent Steffensen, Tyler Gillett, and Josh Levin).
