Deep Water is a 2006 British documentary film directed by Jerry Rothwell and Louise Osmond, and produced by Al Morrow, Jonny Persey and John Smithson. It is based on the true story of British businessman and amateur sailor Donald Crowhurst, as he participated in the Sunday Times Golden Globe Race, a single-handed, round-the-world yacht race held in 1968–69, during which he disappeared. The film reconstructs Crowhurst's voyage from his own audio tapes and cine film, interwoven with archival footage and interviews.
