Auto/manual: allows the user to select between manual steering & autopilot. Officer to steer correct course, rudder to be on amidships, course to steer set (gyro pointer on lubber line), off course alarm set before changing over to autopilot.
Follow up: if the rudder is to be put on starboard 10, the helm is put on starboard 10. When the helm is on midship rudder will return to midships.
Non-follow up: if the rudder is to be put on starboard 10 helm is turned to starboard, a few degrees before starboard 10 the helm is put on midships, rudder then settles on starboard 10. If the rudder goes beyond starboard 10, a slight port helm is to be given. The rudder will remain on starboard 10 even when the helm is returned to midship. To bring it back to midships port helm to be given.
