During the Age of Sail, shore leave was often abused by the members of the crew, who took it as a prime opportunity to drink in excess, indulge in prostitutes, and desert.Amenities ships were expected to provide an alternative to shore leave at remote island anchorages without commercial recreation facilities.[1] The United States Navy has organized a 21st-century liberty and single sailor program for active duty military personnel and their guests 18 years or older.In many science fiction stories in which space travel is depicted, shore leave has the same basic principle but is more metaphorical, as a spacecraft crew does not necessarily disembark to a planetary location with a shoreline.Filk musician Leslie Fish recorded a song based on the original Star Trek television series called "Banned from Argo" that detailed the debauchery and chaos caused by the Starfleet crew on shore leave.
