The operation of the line-up is quite simple. Each surfer waits for his wave, and as the session progresses, a few switches will occur. According to feedback from surfers with a lot of wave experience, after 30 minutes of surfing the rhythm becomes more fluid. Many surfers want to rest to fully enjoy their next wave. 

From this perspective, surfing in a pool differs significantly from surfing in the sea, since continuous physical activity protects from the cold and is relatively intense.
