When Coffs Harbour handyman and avid surfer Andrew Witton left Australia in 2006 it was supposed to be the trip of the lifetime.
His plan was to sail across the South Pacific, visit friends in South America and then make his way to the World Series Cricket in the Caribbean.
Instead he vanished inexplicably from the deck of his beloved yacht Kaileia in a remote part of the Pacific Ocean. His final log entry on the day he disappeared described conditions as 'sunny' and the sea as 'calm'.
The circumstances of his disappearance and the actions of his only crew mate Simon Golding have long troubled and mystified Andrew Witton's family and friends.
