A former attraction was the 19th-century ironclad ram ship HNLMS Buffel, which was moored outside of the museum.
The ship was moved to Hellevoetsluis in 2013 (due to cost cuts) where it will be exploited by the Stichting Museumschip de Buffel to preserve this ship for the generations to come.

The Maritime Museum Harbour includes the red cast iron Low Light of the Hook of Holland, which formerly stood at the entrance to the Nieuwe Waterweg (New Waterway).
Furthermore, it includes a wide range of steam tugs, a steam driven sheerleg and the only working grain elevator in the world.
A diverse range of historical inland vessels is also exposed here.
Visitors are able to enter most of the ships.
In the summer the Museum organizes cruises through the city of Rotterdam with these ships.
