Claude Maki

Claude Maki is a Japanese surfer, actor and hip hop rapper born in Tokyo on 3 October 1972, the eldest son of the actor and singer Mike Maki and the Japanese-American actress Bibari Maeda. English Wikipedia describes him as a surfing and flight champion and lists surfing as his hobby, and it records the surfing role he took in Takeshi Kitano's 1991 film A Scene at the Sea, in which he played a deaf-mute surfer. Outside sport he built a screen career that began on NHK television in 1987 and brought him the Japanese Academy Award for Best Newcomer in 1989, and he records as a rapper under the stage name A.K.T.I.O.N. The article gives no competition results, so this entry rests on the stated championship claim and the surfing connection only.
