Spacecraft
The ships of the Vogon Constructor Fleet were described as "impossibly huge yellow somethings" that "looked more like they had been congealed than constructed" and "hung in the air in much the same way that bricks don't" (the colour being a parallel to bulldozers that demolish Arthur's house); they are said to be undetectable to radar and capable of travel through hyperspace. They are not crewed exclusively by Vogons; a species known as the Dentrassi are responsible for on-board catering.
In the television version of the story, the craft are shaped like battleships, albeit with a flat bottom through which the demolition beams are fired. In the film version, the craft are grey and cubic, a continuation of the emphasis on bureaucracy in the Vogons' conception: "Douglas 's description of the Vogon ships hanging in the air in much the same way that bricks don't these Vogon ships which are these massive concrete tower blocks, with hardly any windows, they just have a few doors around the base," says Joel Collins.
