Ben Gravy, the New Jersey-based surfer and vlogger known for his wild and wacky "novelty wave" pursuits, has done it again! This time, he's taken his talents to the high seas riding the waves created by some of the largest cruise ships sailing out of Miami.

Gravy, whose name is synonymous with shredding unconventional swells, has already surfed everything from river waves to the wake of a ferry and even the collapse of a glacier. But his latest stunt? Absolute madness! The YouTube sensation and semi-pro wave chaser decided to ride the waves of the massive Carnival Horizon, Norwegian Bliss, MSC Seascape, and the world’s largest cruise ship Icon of the Seas as they departed the port Miami.

This is just another notch on the belt for the man who became the first person to surf in all 50 U.S. states—an achievement documented in his m For the Dream. His fearless approach to wave-riding has earned him a cult following, and his latest stunt is sure to fuel the hype even more.
