ABSTRACT:
An illustrative embodiment of the invention provides a ship's steering system or helm adapted to provide a control signal to the ship's rudder such that the response of the rudder to the rotation of the helm is substantially non-linear from hardover to hardover wherein a portion centered about midship is linear such that hardover to hardover rudder can be ordered in less than one turn of the wheel. That is, less rotation of the wheel is necessary when large helm or rudder orders are required for heading changes and a greater rotation of the wheel about midships is necessary to desensitize rudder changes to large wheel rotations in order to make heading keeping easier.
