History of surfboard shaping

Hawaii gave the world the surfboard. Then it spent the next two hundred years inventing the board that could survive a big wave. The story of surfboard shaping is not really a story about wood and foam — it is the story of Hawaiian surfers meeting Hawaiian waves that kept sliding out from under them, and reshaping the board, curve by curve, until it held.

The boards the aliʻi rode

Before contact, Hawaiians shaped four kinds of surfboard, and the board you rode said something about who you were. The olo was long, thick, and rounded — a board for gentle, rolling swells, associated with the aliʻi, the chiefs. The alaia was thinner and faster, seven to nine feet, the everyday board and by far the most common; ten of the thirteen boards in the Bishop Museum’s early collection are alaia. Between them sat the kikoʻo, a harder-to-handle in-between board, and the paipo, a short prone board often ridden by children.

The wood mattered as much as the shape. Olo were classically cut from light wiliwili; alaia and paipo from koa or ʻulu (breadfruit). By tradition — the account comes down to us through Thomas Thrum’s 1896 almanac — a shaper chose a tree, a kahuna offered a prayer, and a red kumu fish was placed in the hole left by the roots as an offering. Whether that ritual belonged to surfboards or was borrowed from canoe-building is debated, but the reverence behind it was real: the board was not a product, it was a relationship.

The shaping itself was slow, patient work. With adzes and stone the blank was roughed to shape, then rubbed smooth with coral and rough stone, stained dark with the soot of burned kukui nuts or the juice of pounded bark, and finally sealed with kukui-nut oil so the wood would slide. A finished olo could take days and belonged to a family for a lifetime. You can read the full story of these boards in our guide to ancient Hawaiian surfing and the deeper board typology in olo, kikoʻo, and alaia.

The century the shaping stopped

When missionary pressure and introduced disease swept the islands in the 1800s, surfing very nearly disappeared, and the craft of shaping went with it. The population collapsed, the old breaks emptied, and the knowledge that had produced the olo and the alaia — which trees to fell, how to read the grain, how to finish a rail — survived in only a handful of hands. A few boards were preserved in museums; a few families kept riding. But for most of a century the living tradition of Hawaiian shaping hung by a thread. That near-extinction is why the next chapter is called a revival rather than an evolution: Hawaiian shaping did not develop smoothly into the modern board. It had to be deliberately brought back.

Redwood and the Waikīkī revival

The revival ran through Waikīkī, and its most famous figure was Duke Kahanamoku. The boards of the early 1900s were solid planks — often California redwood, heavy enough that carrying one was its own athletic event. They had no fin and almost no rocker, and they went more or less where the wave sent them. The Waikīkī beachboys rode them, taught visitors on them, and in doing so carried surfing back into the wider world. But those planks also set the stage for the first person to treat the surfboard as an object that could be engineered rather than merely carved — something to be redesigned, not just re-carved from a bigger log.

The redwood plank — wide, finless, and hard to hold in a steep wave

Tom Blake changes the object

Tom Blake was a Wisconsin transplant who fell in love with Hawaiian surfing and then started asking why the board had to be a solid slab at all. Around 1929 he built the first hollow board — drilled out, sealed, and dramatically lighter — and patented the idea in 1932. Then, in 1935 in Waikīkī, he did something even more consequential: he bolted a roughly twelve-inch metal keel, salvaged from an old speedboat, to the bottom of a board. It was the first surfboard fin. Most surfers ignored it for years. But Blake had introduced the two ideas — reduce the weight, control the direction — that the next fifty years of shaping would chase.

The hot curl

Here is the hinge of the whole story, and it happened not in a factory but in a backyard. In 1937, a group of young Oʻahu surfers kept getting humbled at Brown’s, a steep, glassy south-shore break where their wide-tailed redwood planks would “slide ass” — the tail would let go and spin out just as the wave stood up. Frustrated after one pounding, John Kelly and Fran Heath hauled a board back to Kelly’s house on Black Point, set it on sawhorses, and Kelly took an ax to the tail. “However deep this ax goes,” he reportedly said, “I’m going to cut that much off.” They planed it down to a narrow, V-shaped tail — maybe five inches across — and paddled back out.

The board held. For the first time the steep tubes at Brown’s could be ridden clean instead of sideways. A day or two later Wally Froiseth watched the boards drive through sections that used to spit them out and shouted that they really got you into the hot curl — and the name stuck. The hot curl had no fin; the deep V of the tail did the gripping. It was, in every account that matters, surfing’s first purpose-built board for bigger, faster waves — the moment Hawaiian surfing stopped adapting an old object and started designing against a specific wave.

For the next fifteen years the hot curl was the Hawaiian board for anyone who wanted to ride steep, serious surf. It was demanding — the narrow tail asked for constant trimming and gave beginners nothing to hold onto — but in the right hands it opened water that planks simply could not. Kelly, Froiseth, and Fran Heath deserve — and now have — a full biography of their own on this site.

Makaha, and a board built to go bigger

The hot curl did exactly what a breakthrough is supposed to do: it took its makers somewhere new. Holding in steeper surf, Kelly, Froiseth, and their circle pushed out to Makaha on the west side and began, for the first time, to seriously ride size. But the finless V-tail had a ceiling, and the surfer who found the next rung was George Downing.

Downing — Irish-American, born and raised in Honolulu in 1930 — built a board for the 1950–51 Makaha season that he called “The Rocket.” It was an all-balsa pintail, far lighter than redwood, and it carried a redwood fin box with a wedge-in wooden fin he could slide fore and aft. That made it, by common reckoning, the first removable and adjustable fin — a different milestone from Blake’s fixed 1935 skeg, and one aimed squarely at big waves. The Rocket is generally called the first true big-wave gun: a long, narrow, drawn-out board built not to turn tightly but to hold a high line at speed across a wave too big for anything else.

Makaha became the proving ground. When the Makaha International began in 1954 it was the most important contest in the sport, and Downing won it that first year — the west side, not yet the North Shore, was where Hawaiians were learning how big a rideable wave could be. Downing himself would win Makaha three times and, decades later, serve as the man who decided whether the surf was big enough to run the Eddie.

The gun — long and drawn to a pin, built to hold at speed

The gun comes to the North Shore

By now the material itself was changing. Through the late 1950s balsa gave way to the polyurethane foam and fiberglass that every modern board is still built from — a blank a shaper could reproduce exactly, rather than a rare, perfect log that had to be hunted down. That is what made a precise big-wave gun repeatable in the first place, and it moved the frontier north. Waimea Bay was ridden for the first time in 1957, and the biggest waves in the world demanded a board built for nothing else. The shaper who defined it was Dick Brewer. Brewer refined the pintail gun into a precise instrument for Waimea and Sunset, obsessing over the balance point and the way a drawn-out tail could be trusted at speed. Then in 1967 he cut a 9’6″ down into what became the mini-gun — shorter, drawn-out, hard-railed — one of the boards that tipped surfing into the shortboard era and made Brewer, for a stretch, the most influential board designer alive. From the finless hot-curl V to Downing’s balsa pintail to Brewer’s gun, you can trace a single idea narrowing down the tail of the board across thirty years: hold in the wave, no matter how big it gets.

The shapers who carried it

Hawaiian shaping is a lineage, passed from hand to hand and from master to apprentice in shaping bays from Waikīkī to the North Shore. These are some of the shapers whose boards define it — click through to the ones whose stories we have told in full.

Still shaping

This is not a museum craft. Barry Kanaiaupuni — the power-surfing icon of 1970s Sunset Beach and an International Surfboard Builders Hall of Fame inductee — still hand-shapes boards out of Haleiwa, turning out guns and longboards by the week. Eric Arakawa has been shaping high-performance boards on Oʻahu since 1974, and his surf under a decade of world champions. The tools have changed — computer-cut blanks now do the rough work a drawknife once did — but on the North Shore the last pass is still a shaper, a block of foam, and an eye trained by the same waves that humbled those redwood planks at Brown’s in 1937.

Frequently asked questions

Who invented the surfboard?

Hawaiians did. Surfing — heʻe nalu, “wave sliding” — and the boards built for it originated in the Hawaiian Islands centuries before Western contact, in the four traditional forms: olo, alaia, kikoʻo, and paipo.

What is a hot curl surfboard?

A hot curl is a finless redwood board with a narrow, deep-V tail, created in 1937 when John Kelly and Fran Heath cut down the wide tail of a plank so it would hold in steep waves instead of sliding out. It’s regarded as surfing’s first specialized big-wave board.

Who made the first big-wave gun?

George Downing, with his balsa pintail “Rocket,” built for the 1950–51 Makaha season. It also introduced the first removable, adjustable fin — distinct from Tom Blake’s fixed fin of 1935.

Is Barry Kanaiaupuni still shaping?

Yes. Barry Kanaiaupuni, born in 1945, still hand-shapes surfboards in Haleiwa on Oʻahu’s North Shore, producing guns and longboards regularly.

What wood were Hawaiian surfboards made from?

Traditional boards were shaped from koa and ʻulu (breadfruit) for alaia and paipo, and light wiliwili for the chiefly olo. The famous surviving royal olo in the Bishop Museum, however, is koa — large enough wiliwili was hard to source.
