5.1 All Polar Class ships should be provided with
directional control systems of adequate strength and suitable design
to enable efficient operation in polar ice-covered waters.
5.2 For the purpose of this chapter, a directional
control system includes any device or devices intended either as a
primary or auxiliary means of steering the ship. The directional control
system includes all associated power sources, linkages, controls and
actuating systems.
5.3 Attention is drawn to the interaction between
directional control systems and propulsion systems. Where such interaction
occurs or where dual purpose components are fitted, the provisions
of chapters 7 and 8 should also be complied with, as applicable.
