Heavy waves with a shallow, super sharp reef break. The Pipeline break is treacherous in Hawaii.
According to the great and powerful Wikipedia: "it got its name in December 1961, when surfing movie producer Bruce Brown was driving the North Shore with California surfers Phil Edwards and Mike Diffenderfer. Brown stopped at the then-unnamed site to film Edwards catching several waves. At the time, there was a construction project on an underground pipeline on adjacent Kamehameha Highway, and Diffenderfer made the suggestion to name the break "Pipeline". The name was first used in Brown's movie Surfing Hollow Days."
By the way, Surfing Hollow Days is highly recommended viewing material!
Here's a Hawaiian warrior, charging Pipeline with no fear in his eyes.
I've been thinking about the 60's and 70's Ed Roth and Roth industries T-shirts that my dad started buying for me as a kid and how that look definitely informed my decisions when drawing characters or even designing. For better or worse, I love drawing this way.
