Jog Steering vs Follow-Up
Let's clear up terms 'Jog' and 'Follow-up'.
Follow-up steering uses feedback from a rudder angle sensor to position the rudder exactly as the control handle is positioned. The handle or knob stays where you put it and the rudder follows to that position and stops. The lever has a center detent. This is a nice system to have for maneuvering, you know by feel where the rudder is, and you can move your hand to another thing without waiting for it to get there. FU steering capability is integrated into some autopilots, and can also be a stand-alone system - that's getting into commercial/large yacht equipment. The FU lever unit will be specific to the pilot.
Follow-up steering also refers to a power-assisted steering system using a master and slave ram arrangement.
Jog steering has a spring loaded lever, the rudder is driven as long as the lever is held. Most autopilots have a jog steering function, including limit stop via the rudder feedback unit. Some pilots will have connections for an external jog switch. Any kind of momentary switches are compatible with jog steering.
Jog steering can be added independent of the pilot, details differ depending on the drive type and are a bit too much to include here. Limit switches need to be installed and a selector switch so that pilot and jog can't be active at the same time.
