1.Vessels shall be fitted with a reliable steering system which provides at least the manoeuvrability required by Chapter 5.
2.Powered steering systems shall be designed in such a way that the rudder cannot change position unintentionally.
3.The steering system as a whole shall be designed for permanent lists of up to 15° and ambient temperatures from — 20 oC to + 50 oC.
4.The component parts of the steering system shall be rugged enough to always be able to withstand the stresses to which they may be subjected during normal operation. No external forces applied to the rudder shall impair the operating capacity of the steering apparatus and its drive unit.
5.The steering system shall incorporate a powered drive unit if so required by the forces needed to actuate the rudder.
6.A steering apparatus with powered drive unit shall be protected against overloads by means of a system that restricts the torque applied by the drive unit.
7.The penetrations for the rudder stocks shall be so designed as to prevent the spread of water-polluting lubricants.
