Rudder-like is a term used to describe something that is similar in function or design to a rudder. Synonyms for rudder-like may include steering, guiding, navigational, directional, controlling, or piloting. These words are often used to describe objects or systems that help to steer or guide a movement, whether it be a physical vessel or a metaphorical concept. For example, a steering wheel in a car is a navigational tool that is similar to a rudder on a ship. Similarly, a leader may be described as possessing strong guiding or piloting abilities, much like a skilled captain with a steady hand on the ship's rudder.
