MS Zuiderdam is a owned and operated by Holland America Line (HAL). It is the lead ship of the Vista-class vessels, so named for the extensive use of glass in their superstructure, and is sister to three other HAL ships, , , and . The prefixes of the four ships' names represent the four directions of the compass in Dutch. The ship shares similar exterior dimensions with Carnival Cruise Lines' and Costa Cruises' . Cunard Line's is an enlarged version of the same design, as is HAL's Signature class. As with all Vista-class ships, Zuiderdam is equipped with a diesel-electric power plant and an Azipod propulsion system, and eighty-five percent of her staterooms have ocean views and sixty-seven percent have verandahs. Her art collection carries a Venetian theme throughout the ship; the most dazzling features figures in the time of Carnival in Venice, created by Daniel Ogier. Service history Zuiderdam was christened by American broadcaster Joan Lunden at Port Everglades on 14 December 2002. Between October to April, Zuiderdam largely runs a southern Caribbean itinerary which includes a half-transit of the Panama Canal through the Gatun Locks. From May to September, the vessel travels to Alaska or the Northern Europe/Baltic region. On 9 June 2019, the ship's departure from the Kiel was delayed when members of climate activist group Smash Cruiseshit used smaller boats, blocking the seaport. Technical information The machinery spaces of Zuiderdam are vast and stretch along with two of its lowest decks for the most part of the vessel. MS Zuiderdam is powered by a CODAG propulsion system encompassing five (three 16-cylinder and two 12-cylinder) Sulzer ZAV40S diesel engines (built under license by Grandi Motori Trieste, now owned by Wärtsilä, in Trieste, Italy) and a GE LM2500 Gas Turbine. Zuiderdam was the first Holland America Line ship to use a CODAG propulsion arrangement, a GE LM2500 turbine or ABB Azipod propulsors. It is propelled by two 17.62 MW, 160 rpm synchronous freshwater-cooled ABB Azipod propulsors.
