A magnetic compass is an instrument designed to seek a certain direction in azimuth and to hold that direction permanently, and which depends, for its directional properties, upon the magnetism of the earth.
The standart compass is a magnetic compass used for navigation, mounted in a suitable binnacle containing the required correcting devices and equipped with a suitable azimuth reading device.
The steering compass is a magnetic compass used for steering purpose mounted in a suitable binnacle containing the required correcting devices. All ships irrespective of size shall have:
a properly adjusted standard magnetic compass, independent of any power supply, to determine the ship’s heading and display the reading at the main steering position;
a pelorus or compass bearing device, independent of any power supply, to take bearings over an arc of the horizon of 360°;
All ships of 150 gross tonnage and upwards and passenger ships irrespective of size shall, in addition to the requirements of paragraph above, be fitted with a spare magnetic compass interchangeable with the magnetic compass, as referred to in previous paragraph.
