Section 27(2) in The Merchant Shipping (Cargo Ship Construction And Survey) Rules, 1974
(2)Where there is no emergency steering position, two magnetic compasses and binnacles shall not be required, provided that the ship is equipped with a standard projector magnetic compass and a gyrocompass with repeaters and provided also that a spare magnetic compass bowl with its gimbal units is carried on board so that it may be interchanged with the standard compass if that compass should become unserviceable.
