Kelly Slater, Rob Machado and a circle of Hawaii-raised friends turn a teenage surf obsession into a defining chapter of the sport's history in this 2018 documentary.

What is Momentum Generation about?

In the 1990s a loose group of teenagers on the North Shore of Hawaii treated surfing less as a hobby than as a shared identity, pushing each other in the water and out of it as they chased a place in the sport's professional ranks. The documentary traces how that circle of friends, competitors and roommates rose together from local contests to global stardom, reshaping competitive surfing's style and culture along the way. Rather than isolating one athlete's rise, the film follows the group dynamic itself, the rivalries, loyalty and shared risk that came from young surfers pushing one another toward bigger waves and bigger stakes. Archival footage from the era sits alongside present-day reflection, giving the film a sense of both the reckless momentum of youth and the longer view of what that decade built for the sport.

Context & significance

Momentum Generation, directed by Jeff Zimbalist and Michael Zimbalist, is a 2018 American documentary that captures a specific turning point in competitive surfing, the moment a group of teenagers from one place became the sport's defining generation on a world stage. The filmmakers use the group's own home-video footage and later interviews to build a picture of the 1990s surf scene from the inside, rather than narrating it from a distance. That insider access sets the film apart from typical sports documentaries, since much of what it shows was recorded by the surfers themselves long before anyone expected it to become a historical record.
