Dr. Tom Lewis OAM is a military historian. His latest work is The Empire Strikes South, the story of the Japanese aviators who died across the Top End in WWII.
They were first used in Christopher Columbus’s ships when his sailors observed natives using them in the Caribbean Islands slung between trees. The name ‘hammock’ actually comes from the Caribbean word hamorca.
Hammocks could only be slung at certain times, no matter how long the user wanted to sleep, as the spaces in which they were slung also served as the messdeck. And if you didn’t responded quickly enough to “wakey wakey” you were unceremoniously tipped out of your hammock.
The phrase ‘show a leg’ related to the women waiting in the harbours. These women were allowed in the Royal Navy (RN) as long as they declared they were seamen's wives. If the call ‘show a leg’ issued from within a hammock (and the leg in question was smooth) the duty rating left the occupier in peace.
The use of hammocks continued in the Royal Australian Navy (RAN) through to the 1970s. Stoker John Day used them in the 1950s on corvettes but bunk beds began to replace slung arrangements. Lieutenant Errol Hunt, a sailor in the 60s, used a hammock on board HMAS Duchess until 1971. He remembers some of the problems. If you were “stepping” (going ashore) at 1600 you could not sling your hammock until after rounds at 1900. This meant sailors were often putting their hammocks up “under the influence.”
In WWII corvettes hammocks were stored in a seven foot square bin on each side of the accommodation compartments. Ship’s company members were not allowed to sling them until the second dog watch, and hammocks were struck at 0600 the next morning for dawn action stations. John Day remembers that there was no sleeping past that time no matter what watch you’d kept. Ships in combat areas went to dusk and dawn action stations with all personnel.
Imagine trying to sleep with around 20 people fitted into the space of an average suburban bedroom. WWII ships were overcrowded as extra ship’s company members were added as radar and more AA guns were positioned. The sailors’ discomfort was increased by a lack of ventilation. The whole vessel was darkened with scuttle covers every night to stop light leakage.
Before WWII officers’ cabins featured “cots”, wooden beds slung from the bulkhead, allowing the user the privilege of sleeping on a hard surface to support a straight spine.
A hammock was also useful as a shroud when one was being buried at sea. Tradition has it that the last stitch of the hammock being sewn up was through the departed’s nose, just to ensure he was actually dead.
