The rudder and rudder device make one of the most important elements on board. This paper describes the types and methods of steering and how steering gradually developed. From the simplest rudder designs in which human strength was most pronounced to today's modern rudder devices and rudders. From the very beginning of ships, steering developed slowly and the rudder designs were the simplest possible, only with the advent of steel ship structures, rudders and rudder devices reached an enviable level in terms of maneuvering and steering the ship. The transition from wooden rudder to steel and the transition from single-plane to double-plate rudder and some newer versions such as schilling rudder and flap rudder, as well as the transition from manual and mechanical steering to electro-hydraulic steering has made a significant step forward. Apart from the fact that the size of the devices themselves has decreased, our reliability itself has also increased. The SOLAS Convention with its regulations and laws has greatly contributed to the reliability and improvement of the rudder device performance. Thus, from paddle steering today, we have reached the two most common versions, which are the electro-hydraulic piston and rotary vane steering devices. In these devices, the main medium is oil, which, under the pressure obtained by the pumps, rotates the rudder.
