Ark (vehicle)

An ark was a vehicle, often a boat, designed to support large numbers of passengers and carry supplies for great lengths of time.

When sea levels rose on Minuea, the inhabitants built hundreds of arks laden with grain and livestock. These arks set out to find new land, but were easy prey for pirates. (PROSE: The Tomorrow Windows)

The First Doctor, Steven Taylor and Dodo Chaplet twice visited a large spacecraft which Dodo named the Ark, once at the beginning and once at the end of its journey. (TV: The Ark)
