The Fancy was the sailing ship (frigate) of Captain Henry Avery.
In 1699, the ship was stranded in the same spot as a spaceship from another universe. The spaceship's virtual doctor came to Fancy to heal all members of the crew who were sick or injured. However, the crew believed the virtual doctor to be a sea siren who had come to kill them. Eventually, Fancy's entire crew was taken to the other universe and they flew the spaceship away from Earth. (TV: The Curse of the Black Spot)
Its crew included Henry Avery, the boatswain, Mulligan, De Florres, Dancer and McGrath.
