I surf a busy break - VERY BUSY !!!! Down under.........
Anyhow I'm just considering peoples thoughts when people call waves on an extremely busy beach break......... I find it annoying as hell when theres five people paddling for a wave and some one calls it although they are in no better possy as the other four people. At busy breaks like this one I tend to ignore someone calling it and paddle for hell for it and then only pull off if that person then starts to plane or pop up first. Otherwise IMHO they are really being overly confident or cocky to be calling it..... and I get mightily pi**ed off if they call it and then fail to make it so the wave goes un ridden.
I honestly think at over crowded beachies certain etiquettes dont apply and that the location istelf and the amount of people jokeying for the wave kind of have to self regulate on the day. I rarely see the older locals calling waves...... and when they do they tend to be deeper and up and already riding.
