Back in the day, before the foam blank ever saw the inside of a shaping bay, the original surfboards were heavy, solid planks of koa wood, carved by ancient Hawaiian ali‘i with nothing but stone adzes and pure stoke. Those boards were sacred, weighing well over a hundred pounds, and only the most skilled watermen could even dream of wrangling them into a wave. But the real game-changer in surfboard evolution, the one that truly unlocked the doors for everyday surfing like The Endless Summer chased, was the arrival of balsa wood. And here’s the wild part: after decades of being shelved for foam and epoxy, balsa is making a comeback, and the story of why that matters tells us everything about where we’ve been and where we’re going.
In the 1930s and 40s, when Tom Blake was busy revolutionizing the sport, he figured out that cutting weight was the key to surfing for the masses. He hollowed out redwood planks, then experimented with balsa, which was lighter than cork and floated like a dream. Balsa boards, wrapped in a thin skin of mahogany or plywood, dropped the weight down to thirty or forty pounds. Suddenly, a guy could actually carry his own board to the beach, paddle through the whitewash, and feel the wave lift him before he even stood up. That was the dawn of the modern longboard era, the era of the “Malibu chip” and the classic 50s noserider. Balsa had a flex, a liveliness, a feel that foam just couldn’t replicate. It absorbed the ocean’s energy in a way that made every turn feel organic.
But balsa had a dark side. It dented if you looked at it wrong. It soaked up water like a sponge if the glass job cracked. It was fragile, expensive, and inconsistent. By the 1960s, polyurethane foam blanks hit the scene, and surfboard evolution took a sharp turn toward the shortboard revolution. Foam was cheap, easy to shape, and incredibly strong when glassed with polyester resin. It allowed shapers like Bob Simmons, Dick Brewer, and Skip Frye to experiment with fins, rockers, and plan shapes that balsa simply couldn’t support. The era of pulls, cutbacks, and tube riding was born from foam. Balsa became a relic, something you’d see hanging on the wall of a surf museum, a piece of history that everyone respected but nobody rode.
And then, something shifted. About a decade ago, a new wave of shapers started looking backward to move forward. These modern craftsmen, guys like Ryan Lovelace, Tyler Warren, and the crew at Grain Surfboards, began experimenting with hand-shaped, hollow, and solid balsa boards. They figured out how to use modern epoxy resins and carbon fiber stringers to solve the old water-absorption and dinging problems. The new balsa boards were lighter than ever, incredibly responsive, and they carried that unique flex pattern that foam could never mimic. Suddenly, a surfer could paddle out on a fifty-year-old silhouette and feel a connection to the wave that was totally different from riding a high-performance shortboard with a thruster fin setup. The board would hum beneath you. It would load up on a bottom turn and release with a subtle, spring-loaded snap that felt like the wave itself was doing the work.
Why does this matter for the culture of The Endless Summer? Because the revival of balsa represents a return to soul. It’s not faster. It’s not necessarily better for a steep, hollow reef break. But it is profoundly more personal. Riding a balsa board is like playing a hand-carved guitar instead of a mass-produced electric. You feel every grain. You taste the history. Shapers today are using sustainably harvested balsa from Ecuador, pairing it with reclaimed wood or paulownia stringers, and creating boards that are as much works of art as they are functional tools. It’s an antidote to the cookie-cutter factory boards that dominate the racks. It’s a nod to the craftsman spirit of the 50s, the golden era when surfing was less about competition and more about just chasing the sun, finding a clean wave, and feeling the glide.
So if you ever get the chance to paddle out on a modern balsa replica, do it. You won’t close out the Banzai pipeline on it, but you might find a new love for the pure sensation of surfing. That’s the evolution of the surfboard coming full circle. The old ways return, reimagined for a new generation. And as long as there are waves and surfers who care about how a board feels rather than just how it looks, the balsa will always have a place in the lineup.
