Aken was the patron and custodian of the boat named "Meseket" that carried the souls of the dead into the underworld. Apparently he remained in a deep sleep when he was not needed, and had to be woken by the Ferryman, Mahaf, when the dead required his services. He was generally depicted as a sailor standing in the stern of a papyrus boat. He was not the focus of worship, and had no cult centre but is referred to a number of times in the Book of the Dead.
Aken is sometimes associated with Kherty (or Cherti) a more ambiguous deity who was considered to be a god of the underworld and the ferryman of the dead
