2 surfers on a left paddling for the wave, both are outside of the peak. The surfer furthest away uses a long(er) board and is maybe a fraction of a second earlier on his feet. Maybe, hard to tell.. But, he goes RIGHT! So he takes off, in his perspective, from behind the peak. If the surfer closest to the peak takes off to go left there is a high risk of frontal collision.
I was almost in this situation this morning, I was the surfer closest to the peak going left. Or I would have, if I had not screwed up my paddling by laying too much forwards on my board. I had to abort because risk of pearling. But I was shocked in seeing the other guy race to the right. I was not expecting that and it made me think what does surfer etiquette tell us about how to best solve a situation like this?
I didn't talk to the guy later because there was no problem due to my accidental abort, and maybe the guy had the skills to react on my last second abort, he looked like he knew what he was doing. Also the guy looked Chinese or Korean and, in combination of my experience and my putty-earplugs, that gives too much language barriers to discuss an abstract etiquette question..
