Pressing the knob of the model of the Zuidersluis opens the sluice doors. A water bath which can be operated by children and which illustrates how the locks of the sluices work, is in production. In the Fisheries Hall visitors can see round the bunk bed of a cutter and can take the altitude of the sun using an enlarged model of a sextant. In a diver's corner, visitors can try on a genuine diver's helmet and imagine what it is like to really go underwater. The older junior school age children can explore the radar, Morse key and other communications equipment.
Groups can also visit the museum outside opening times.
Guided tours are also available.
