The Rotterdam class is Holland America Line's elegant mid-size design of the late 1990s, built by Fincantieri in Italy and delivered between 1996 and 2000 at 61,214 to 62,735 GT. The four ships pair traditional ocean-liner touches — a wraparound promenade deck, a two-level dining room and a collector's-art atmosphere — with a size small enough for varied, port-focused cruising. In this phase of the directory the class is evenly split: Volendam and Zaandam still sail for Holland America, while their sisters have become Borealis and Bolette, flagships of Fred. Olsen Cruise Lines, where their classic profile suits the British line's traditional style. Few classes have divided so neatly between two like-minded operators.
