Kai Lenny: riding a self-propelled hydrofoil surfboard can be fun | Photo: Tom Servais Jr

Meet the world's first-ever self-propelled hydrofoil surfboard. Who better to test it than Kai Lenny?

Kai Lenny paddled into a left-hand roller, kicked out, pumped his hydrofoil back out to sea, and caught the next wave.

"What I really love about the hydrofoil is that it just opens a whole new world of surf spots. Most of the waves in the world aren't that great, but you get on a hydrofoil, and all of a sudden, it feels like you're riding a perfect wave at Malibu," explains Lenny.

"The sensation of paddling to one wave but having the ability to ride two is by far the best feeling I've had in surfing in a very long time."

Kai Lenny also had the opportunity to enjoy virtually unrideable waves.

In other words, Lenny caught fat rollers that never broke in conditions that wouldn't even be possible with longboards or stand-up paddleboards (SUP).

The young Hawaiian waterman had already successfully tested an SUP hydrofoil designed by Alex Aguera (Go Foils) in downwind conditions.
