Westerdam

MS Westerdam is a Vista-class cruise ship owned by Holland America Line. She is the third ship of the class to be operated by the line, as well as being the third ship to bear the name Westerdam. Her sister ships are Oosterdam, Zuiderdam, and Noordam. The ship's name is a portmanteau of the Dutch word west, the same as 'west' in English, and the suffix -dam, a common Dutch placename suffix used in the names of all Holland America Line ships.
