Holland America also owns the following:  On October 26, 2012, it was announced that a memorandum of agreement had been signed with Italian shipbuilder Fincantieri for the construction of a 2,660-passenger ship for Holland America Line scheduled for delivery in spring 2016. The MS "Koningsdam", which became a new class of vessel for the line (The Pinnacle Class), and the first new Holland America ship since the , delivered in 2010. Also noted was that the addition of new ships would maintain passenger capacity if some of the older Carnival Corporation ships are sold. The Holland America Group of HAL and Princess Cruises have a letter of understanding to buy the Yukon White Pass Railways from Skagway to the US-Canadian border. The purchase will close July 31, 2018. The S Class consists of MS "Maasdam" and MS "Veendam" sailing for Holland America Line, "Vasco da Gama" sailing for TransOcean Tours, and "Pacific Aria" sailing for P&O Cruises Australia. As the first ships ordered and delivered under the line's ownership by Carnival Corporation & plc, the S Class ships were the first new Holland America Line ships to incorporate features including the atrium, the two-deck main dining room and show lounge, and the Lido pool with retractable roof. In May 2014, Holland America Line transferred S Class members MS "Statendam" and MS "Ryndam" to P&O Cruises Australia. Unlike the vessels of the S class, Holland America Line's R class ships did not all start out identical. "Rotterdam", the first of the four, was similar to the S class, but slightly longer and wider, with a third set of passenger stairs/elevators, twin funnels, and some new facilities. The twins "Volendam" and "Zaandam" followed, similar to Rotterdam, but with a different (single) funnel and larger because the aft pool was moved up one deck to the Lido level, creating more space for passenger accommodations below. The final R class ship, "Amsterdam", like a hybrid of Rotterdam and Volendam/Zaandam, incorporates Rotterdam's twin funnels as well as the Lido deck aft pool. Together, "Rotterdam" and "Amsterdam" were considered HAL's flagships. HAL's four Vista class ships are named for the points of the compass in Dutch.
