In the early 20th century, wooden surfboards were long and heavy — measuring 15 feet long and weighing nearly 100 pounds — which prevented many women from taking up the sport.

But by the 1940s and 1950s, Malibu surfers had developed “girl boards,” also known as the “Malibu chip.” These were made of balsa wood and were easier for women to handle.

Whilst surfing was spreading across the globe and growing organically it was a 1959 film about a girl with big ideas called Gidget which catapulted surfing culture into the stratosphere. The film, set around Malibu in California, was a wild success, bringing surfing massive mainstream exposure and nothing would ever be the same again.

Surfing went through the roof in the 1960s. Hollywood jumped on the Gidget bandwagon and filmed more surf movies.

Here are 20 interesting vintage photos of women surfers from between the 1930s and 1960s:
