A low cost electrical rudder indicator for the medium sized power vessel

Abstract

It is an electrical instrument to indicate the rudder angle of the vessel in degrees with respect to the bow of the vessel in the wheeel house.This helps the man at the wheel in manoeuvring the vessel while sailing in general and particular occasions.The mechanical movement of the rudder is converted into an electrical signal using a centre tapped potentiometer and fed to an indicator whose pointer movement is synchronised with the movement of rudder with 180' out of phase.
