Viking Neptune, the ninth ship of the class, represents an important step in the collaboration between Viking and Fincantieri toward the development of sustainable and eco-friendly cruise ships. On board, a 100 kW experimental hydrogen fuel cell module has been installed, a key milestone for advancing technologies and regulations on hydrogen use. Like her sister ships, she has a gross tonnage of about 47,800 tons, features 465 staterooms, and can accommodate 930 guests.
