Surfers need momentum to come up to pace and successfully ride big waves. Noisy jet-skis are typically what is used to tow surfers now, they will be a thing of the past soon.
Thanks to my notoriously poor sense of balance, I’ve never been surfing. Even so, I imagine the part where you catch the wave is a lot more fun than the part where you have to paddle back out. Thanks to the WaveJet, that second part could become a thing of the past.
