Don't Be a Dick
From Doug Werner's "Guide to Longboard Surfing" comes perhaps the best bit of surfing advice that I have read so far: don't be a dick!
To provide a bit of context he's talking about surfing etiquette in general and specifically about the longboarder who sits on the outside hogging all the waves and not letting the shortboarders have a fair share of the spoils:
"As a longboarder you must make a decision to be either a dick or a decent surfing citizen."
Nice one Doug! Straight to the point and brought a smile to my face...
Apart from that the little book's not got all that much depth to it (it covers learning from scratch). But I'm happy to devour any information and tips that I can get my hands on at the moment. There was a pretty useful little bit about cross-stepping that has helped me in the water for sure. I just liked the fun way it was written too and it only cost a couple of quid, second hand, so it was a good buy just to get a few nuggets of wisdom from.
