Bas Jan Ader...

Bas Jan Ader was a Dutch conceptual artist, performance artist, photographer and filmmaker. He lived in Los Angeles for the last 10 years of his life. Ader's work was in many instances presented as photographs and film of his performances.

Ader was lost at sea in 1975 between Cape Cod, Massachusetts and Ireland while attempting a single-handed west-east crossing of the Atlantic in a 13ft pocket cruiser, a modified Guppy 13 named "Ocean Wave". The passage was part of an art performance titled "In Search of the Miraculous". Radio contact broke off three weeks into the voyage, and Ader was presumed lost at sea. The boat was found after 10 months, floating partially submerged 150 miles West-Southwest of the coast of Ireland. His body was never found. The boat, after being recovered by the Spanish fishing vessel that found it, was taken to Coruña. The boat was later stolen.
