John McCarthy and Sandi Toksvig are put on their first challenging night watch as they sail through the maze of futuristic platforms in the Amethyst gas field. With the others sleeping soundly below decks, all is going well until another boat starts flashing a light at them. They realise it is Morse code, but what does it all mean?
Flushed with success, Sandi and John then attempt to go solo in a yacht on the Norfolk Broads.
