Stalling is one of the most critical skills to learn in advanced surfing. When performed correctly, it allows you to generate drag, and reduce speed to match the pace of barrel.
The art of stalling a surfboard requires a deep involvement of your body, not only in straight connection with the wave itself but also with the surfboard.
Getting barreled depends a lot on the behavior of the wave. Wider and perfect-peeling barreling waves are easier to ride than freight train cylinders with occasional falling lips.
