The Acali was a raft which was used in the Acali Expedition or Acali Experiment.
It has also been nicknamed the Sex Raft.
The raft had a complement of eleven people: five men and six women.
The experiment was conceived by Mexican anthropologist Santiago Genovés (who had previously been a crew member of Thor Heyerdahl's Ra expedition) to investigate interpersonal relationships in conditions of limited space and social isolation.
The participants showed a restraint towards aggression which created frustration within Genovés and led him to start to try to create conflict, and at one point he took command of the float.
However, although these attempts were made the group remained peaceful.
