Blake first attempted to ride a wave in 1921 on an old board he found while working at the Santa Monica Swim Club. According to his account, he wiped out badly and waited several years to try again. By 1924, however, his interest returned, to the point that he traveled to Hawaii to learn more about the sport. Upon arrival, Blake attempted to seek out Kahanamoku, only to find that he was not on the island. However, he quickly became friends with Duke's five brothers, all skilled surfers in their own right, and became immersed in the study of surfing and Hawaiian culture. For the next thirty years, Blake would divide his time between Hawaii and the mainland, shuttling back and forth every year except when interrupted by the
Second World War. Over the next decade, Blake rose to eminence in a sport that had until then been largely the province of
native Hawaiians. Back on the mainland, in September 1927, Blake and his friend Sam Reid became the first to surf
Malibu Point, and in 1928, he organized, and then won, the first Pacific Coast Surfriding Championship. In 1930, he entered the Hawaiian Surfboard Paddling Championships using a lightweight board of his own design. He overwhelmed all opposition, setting eight new records in the course of the match. However, his victory sparked some resentment among his native Hawaiian friends, feeling that the new board had given him unfair advantage, and Blake stopped entering races after this. Nonetheless, he continued to compile an extraordinary record of athletic feats. In 1932, Blake, with two friends, made the first successful attempt at paddling the 26 miles from mainland California to
Catalina Island. Then on August 1, 1936, he set a milestone that still stands: entering the waves at
Kalehuawehe near
Waikiki, he made a run estimated at 4,500 feet, the longest recorded surf ride in history. While in Hawaii, Blake became fascinated by the traditional surfboards preserved at the
Bernice Pauahi Bishop Museum in
Honolulu. These included a variety of styles, from the shorter
alaia to the heavy, 16-foot long
olo boards traditionally reserved for royalty including one owned by High Chief
Abner Pākī. On his 1926 visit, he was able to secure permission from the curators to study the boards' construction and restore several of them. He then began his own experiments in improving surfboard design. Up until that point, most modern surfers, even Duke Kahanamoku, used the shorter alaia boards due to the immense weight— up to 200 pounds— of the solid olo boards. Blake initially sought to build lighter olos by drilling hundreds of holes in the board, then covering the openings with a thin outer layer. This was the style of board he used to win the 1928 Pacific Coast Championship. Then after three years of experimenting, in 1929, Blake constructed a hollow board with transverse bracing. In 1932, he received a patent for his hollow surfboard design "and opened the sport up to hundreds of people who weren't able to muscle the heavy plank boards down the beach and into the water." One historian remarked: "Blake changed the whole scene by working on these boards. He single-handedly, without really giving it much thought, changed surfing in a massive, huge way. It was because of this we are doing what we do on boards." Blake's internally braced hollow wooden surfboards were eventually superseded by laminated boards with an interior layer of balsa, then by foam-and-fiberglass designs, but another of his innovations remains a fixture of modern surf- and paddleboards, the "
skeg" or fin. Traditional surfboards were flat-bottomed, but in 1935, Blake experimented by tearing the keel off an old speedboat and attaching it to the bottom of a surfboard. Blake later remembered, "I finally put the fin on the board and went out in the surf, paddled out. In paddling out, the board had an entirely different feeling with the skeg on it, it wasn't entirely a likeable feeling... But I got a pretty good wave and right away found the remarkable control you had over the board with the skeg on it. It didn't spin out, it steered easy, because the tail held steady when you put the pressure on the front. You could turn it any way you wanted it. I knew right from that moment it was a success. I consider it as my good solid contribution to the sport. It gives me a lot of pleasure when I see the kids drive by in their cars with a fin on their board." (According to at least one source, the
San Diego surfer
Woody Brown independently came up with the idea for the skeg shortly afterward, but Brown himself gave Blake precedence: “(I made my first surfboard keel) about '36 or '37, somewhere in there; about the same time. But, I didn't know anything about (Blake) and his experiments with adding fins to surfboards. See, we were all separated out. I was in San Diego and he was in L.A., way up there.") ==Other inventions==
