The Family of Blood's ship was the vessel used by the Family of Blood. It was fitted with a stolen Vortex manipulator to travel through time. It was also invisible to be undetected. When someone got near, a green force field would activate to ensure the safety of the ship.
Whilst Jeremy Baines was searching for a stash of illicit beer hidden in Blackdown Woods, he came across the ship. When he entered, he was found by the Family in their natural forms. After he was possessed, three more humans were kidnapped by their Scarecrows and used as hosts. The ship contained a Hydrokinometer.
When John Smith turned back into the Tenth Doctor, he went into the ship posing as his human alter ego and was thrown onto the controls by Son of Mine. This was a very bad mistake, as the ship exploded, with the Family only narrowly escaping. (TV: Human Nature / The Family of Blood)
