This was a ship with a classic, simple design, which was about twenty yards long and shaped like a flattened salmon. It was admired by Zaphod and Ford when they saw it parked outside Milliways, as it was very clean, very sleek, and completely black. It was so extremely dark that it was hard to make out the shape, and it was almost impossible to tell how close you were standing to it. Zaphod commented that the light "seemed to fall into it", and Ford said that his eyes seemed to slide off it. Zaphod repeatedly attempted to reach out and stroke the outside of the craft and feel the surface, however his hand was stopped, as it was totally frictionless. Zaphod called it "one mother of a mover".
Marvin was able to touch the surface of the ship and open up an entry hatchway, and the interior of the ship was completely black. There were black controls labelled in black, on a black background, with a little light that lit up black, which made it difficult to control the ship. The ceiling and walls of the swaying cabin were also black, as well as the seats, control panel, the instruments and the little screws that held them in place. The thin tufted nylon floor covering was black, and when a corner of the foam underlay was lifted up that was also discovered to be was black.
