PS Skibladner is the world's oldest paddle steamer still in timetabled service, and the only such vessel operating in Norway, sailing on Lake Mjøsa. Built as a side-wheel paddle steamer, she was launched on August 2, 1856, and has a notable history of continuous operation. Her primary purpose was to provide passenger service from the railway station in Eidsvoll to the towns of Hamar, Gjøvik, and Lillehammer along Mjøsa, a route she still serves today, now complemented by sightseeing, dining, entertainment, and cultural events during the summer months. Constructed by Motala Verkstad in Sweden, Skibladner was transported in sections by rail and horse-drawn carts to Minnesund, where she was assembled and riveted together. Originally, she was equipped with twin-cylinder oscillating steam engines. In 1888, her length was increased by 20 feet to expand passenger capacity and to accommodate more powerful triple-expansion diagonal paddle engines built by Akers Mek in Oslo, boosting her power output to 606 horsepower. This upgrade made her the fastest vessel in Norway at the time, capable of reaching speeds up to 15 knots. Throughout her service life, Skibladner has undergone several modifications. She was converted from coal to oil firing in the 1920s, and her boilers were replaced in the 1980s. Today, she is powered by steam generated from fuel-oil burners in twin boilers, with a current operating speed of approximately 12 knots. Despite her age, she has survived two sinking incidents during winter layups—in 1937 and 1967—caused by heeling from moorings. Both times, she was raised and extensively renovated, thanks in part to strong public support. Known affectionately as Mjøsas Hvite Svane, or The White Swan of Mjøsa, Skibladner's home port is Gjøvik, where she is stored each winter beneath a specially constructed glass cover. Her sailing season runs from May to September, with a timetable from late June to mid-August. In 2005, she was designated as a cultural heritage object by the Norwegian Directorate for Cultural Heritage, marking her significance as a historic vessel. Named after Skíðblaðnir, the Norse mythological ship of Freyr, Skibladner remains a treasured maritime icon in Norway.
