Deep Water is a documentary film about a journey around the world in a yacht, the Sunday Times Golden Globe Race. The race was a disaster as most competitors never finished, and one committed suicide, Donald Crowhurst, who is the focus of the documentary. His journey in the race is shrouded by much controversy as he dropped out of the race secretly but attempted to keep in contact by reporting fake positions via radio communication, to make it seem as if he was still racing around the world.
He had issues from the beginning with his boat and faulty equipment, which may have been a factor in his abandoning of his ship and attempt to hide the fact by using radio to contact race officials until his death, which was assumed to be caused by jumping overboard and drowning. His logs show his mental state was declining day by day.
