Normally I try to stay away from crowds and crowded peaks because other people in the water make me lose my concentration at this stage.
But the beach breaks I surf sometimes get really crowded, peaks are pretty close and people shift around from peak to peak.
I don't think there is a real line-up, where whoever is closest to the peak takes the wave, then the next person, etc. I don't know how to assert my place. Maybe it's me failing to see the flow , maybe it's everyone else not giving a crap, who knows.
Any suggestions?
