“Not too many people know unless they take a lesson, but this is the most important rule: Don’t drop in on somebody.
Sometimes it can be hard to figure out where you are in the lineup, especially if you’re inexperienced, but the rule is whoever’s closest to the peak has priority on the wave. If you drop in on the wave you’re putting them in danger, you might crash into them, and, if you don’t crash, you might take their turn and annoy them. You’re cutting in on the lineup.
To a surfer, a wave is the most special thing in the world. You don’t want to take a wave away from a surfer.”
—Mike Reinhardt, surf instructor and co-owner of Locals Surf School on Rockaway Beach, NYC.
