The ferry connection on the Aller between Otersen-Westen has existed since the 16th century.
Until 1954, a 20-metre-long barge ferry was used to ferry horse-drawn carriages and animals across the Aller. Until 1967, a 4.50-metre-long plank boat then took pedestrians and cyclists to the opposite side of the river.
On May 1, 1997, around thirty years after it was decommissioned, this ferry service was resumed. Initially with a six-metre-long plank boat, christened "Marie Hoffmann", the name of the last ferrywoman.
In 2000, on 1 May, the 7.50-metre-long new Prahm ferry was put into operation and christened "Marie Hoffmann II".
On 15 July 2016, the "Marie Hoffmann II" was launched. On July 15, 2016, the "Marie Hoffmann", a new aluminum barge ferry for twelve people and bicycles, was put into service.
Now the "small" and the "larger" solar Aller ferry ensure that pedestrians and cyclists can easily change sides on the Aller cycle path, for example. This is made possible by the power of the sun and the voluntary work of the Heimat- & Fährverein Otersen e.V. This continues the 400-year-old ferry tradition between Otersen and Westen.
