Hammocks as naval bedding

When did hammocks begin and cease to be used by navies?

Their early history is uncertain and some navies may still use them; they were firmly established by the age of sail and remain useful for temporary accommodation surges.

There is no secure single first or final date for naval hammock use. Possible early examples are difficult to identify confidently, and even surviving ships such as Mary Rose do not yield a simple universal answer. Hammocks were firmly established as useful naval bedding by the early modern sailing era. They can still solve a practical problem when a modern ship temporarily surges its personnel beyond normal berth capacity.
