Traffic Rules

"Traffic rules of the surf: courtesy requires that one surfrider does not 'cut-out' or cross in front of another which would spoil his ride."

Tom Blake in Hawaiian Surfriders 1935

Surfing Sizes

"Purposely downplaying wave height became a common surf-world practice in the late 1960s. Before that, surfers generally tried to give an honest appraisal, measuring from crest to trough at the wave's peak height."

Matt Warshaw in The History of Surfing (2010)
