It is difficult to determine which professional skateboarder has broken the most boards, as it is not commonly reported or tracked. However, professional skateboarders are known to go through a lot of boards due to the nature of the sport and the constant wear and tear from doing tricks and landing hard on obstacles.
Skateboarders like Tony Hawk, who is known for performing many of the most difficult tricks and pushing the limits of what is possible, have likely gone through a large number of boards over the course of their career. Other professional skateboarders known for their aggressive style and constant progression, like Nyjah Huston, have also likely broken many boards.
It's also worth mentioning that some professional skateboarders have sponsorships with skateboard brands and therefore have a steady supply of boards to use and break.
In any case, it is clear that professional skateboarders go through a lot of boards in order to progress and perfect their skills. Breaking boards is just a part of the process and cost of being a professional skateboarder.
