Very cool
The Crowhurst story is truly amazing-sailed around in circles in the South Atlantic faking position reports to indicate progress around the world, until the stress of keeping it all plausible, guilt, and who knows what other demons drove him to madness and likely right off the boat.
The scheme came together, IIRC, in the first month or so after the start from the UK, where he realized he had neither the experience, right boat or preparation to actually complete the voyage. This guy had virtually no sailing experience and became terrified-one can almost buy into the logic of staying in the relatively benign South Atlantic..at least that is what I remember
Looking forward to the flick
