the Micronesia and the Philippines provided further references to proas in Spanish records. They also described double-outrigger ships from the Philippines, like the account of the karakoa in Francisco Ignacio Alcina's Historia de las islas e indios de Bisayas (1668) which describes them as "sailing like birds." During his 1740–1744 circumnavigation, Lord Anson applied the term proa to the double-ended Micronesian single-outrigger ships. His fleet captured one in 1742, and Lt. Peircy Brett of made a detailed sketch of the proa. Rev. Richard Walter, chaplain of HMS Centurion, estimated the speed of the proa at twenty miles per hour (32 km/h). Although aware of earlier Spanish accounts of the boats of the Spanish East Indies, Anson's account was the first detailed description of a Pacific proa to the English-speaking world. In the subsequent voyages of James Cook in Polynesia, he referred to the similar native single-outrigger canoes there as "proes", differentiating them from the double-hulled catamarans which he called "pahee" (Tahitian pahi). These accounts fascinated both the British and American public, ushering in a period of interest in the design by sports sailors. Working from the drawings and descriptions of explorers, western builders often took liberties with the traditional designs, merging their interpretation of native designs with Western boat building methods. Thus this Western "proa" often diverged radically from the traditional "proa" to the point that the only shared feature was the windward/leeward hull arrangement. The Proa darted like a shooting star Lord Byron, "The Island", 1823 Modern variations In the Marshall Islands, where the craft were traditionally built, there has been a resurgence of interest in the proa. People hold annual kor-kor races in the lagoon at Majuro, along with events such as a children's riwut race. The kor-kors are built in traditional style out of traditional materials, though the sails are made with modern materials (often inexpensive polyethylene tarpaulins, commonly known as polytarp). A loose group of individuals from all over the world has formed from those interested in the proa, including people with a historical perspective and those with a scientific and engineering perspective. Many such individuals are members of the Amateur Yacht Research Society. Early Western proas In the late 19th century and early 20th century, many in Europe and America became interested in the proa. Western boat builders such as R. M. Munroe and Robert Barnwell Roosevelt (Theodore Roosevelt's uncle) reflected its influence. Into the
