Peter Tangvald

Peter Tangvald (born Per Tangvald, 27 September 1924, died 22 June 1991) was a Norwegian sailor and adventurer. Known as one of the early deep-sea cruising pioneers and for his 1966 book Sea Gypsy, he reached notoriety after two of his seven wives had been lost at sea.[1][2][3] He himself drowned, along with his daughter Carmen, when his engineless yacht was wrecked in Bonaire in 1991.[1][2] His son Thomas escaped the accident, but suffered a similar fate when his own yacht was lost at sea years later, in 2014.[4][5]
