How boards learned to fly

   First European written account of Hawaiian surfing

   Lieutenant James King, on Cook's third voyage, described Hawaiians at Kealakekua Bay riding swells prone on oval wooden planks in early 1779. William Anderson's 1777 Tahiti note on canoe-surfing is earlier but is not board-riding.

   correctedDoc lists surfing only as 'Pre-modern'. 1779 is the first written European record, not the start of surfing, which is far older in Polynesia.

   Olo, alaia and paipo: the Hawaiian board classes

   Pre-contact Hawaii had three main board types. The olo was a very long, thick, finless board tied to the ali'i (chiefs). The alaia was a thin mid-length board anyone could ride. The paipo was a short board ridden prone. The best-known surviving olo is the one credited to high chief Abner Paki, ridden at Waikiki in the 1830s and now in the Bishop Museum.

   correctedWood is contested. EOS says olos were usually wiliwili, but Blake's captions describe Paki's olo as koa, and the museum has no surviving wiliwili olo.

   Forlanini starts ladder-foil experiments and files patents

   Enrico Forlanini began hydrofoil work around 1898 using stacked 'ladder' foils: as speed rises, fewer rungs stay submerged. His patents came later: Italy 1904, and Britain and the US in 1905 (US 1,112,405, filed April 1905, granted 1914).

   correctedThe doc's '1898 patent' is not supported by any patent found. 1898 is when the work began. The earliest patents found are Italian (1904) and British/US (1905); the US grant came in 1914.

   correctedThe doc's '≈114 km/h' is right; the exact date is 9 Sept 1919. Lift's claim that the record 'stood for two decades' is wrong, since Gar Wood beat it in 1920. The Musée de la Plaisance gives '70.86 knots' (should be mph), and USA Water Ski gives '60 knots'.

    Blake studied the Bishop Museum olos, then from 1926 lightened a solid board by drilling it and skinning it with veneer. By 1929 he had a 16 ft chambered paddleboard. These led to the 'cigar box' hollow board that made boards far lighter.

   Dana Brown's documentary Step Into Liquid (released August 2003) included a hydrofoil segment of Laird Hamilton and Dave Kalama on Maui. For most viewers this was the first sight of surf foiling.

   correctedThe doc says 2003 but names no film; the film is Step Into Liquid (Aug 2003). No source was found confirming foil footage in Riding Giants (2004).

They showed it to Takoon and Cabrinha in 2004, and the first bow kites went on sale in August 2005 (e.g. the Cabrinha Crossbow). These allowed near-total depower.

The first surf foils were towed: the rider needed a boat or a jet ski to get airborne. Tareah Hendricks’ patent describes a prone board with a rear wing and a small front canard, meant to take off from a wave alone. It says the tow boards needed outside power; this one would not.
