When the Hawaiian natives invented surfing they did it naked. When Mark Twain visited Hawaii in 1866 he wrote “In one place we came upon a large company of naked natives, of both sexes and all ages, amusing themselves with the national pastime of surf- bathing.” Clearly the Hawaiians were on to a good thing. Too bad the missionaries messed that up.
But surfing and nudity wasn’t over. Long before wetsuits were invented, early American surfers like Tom Blake and George Larson used to surf nude at San Onofre, then a remote beach well south of Los Angeles.
