Steering a ship without a rudder is challenging but not impossible. Without it, vessels must rely on alternative methods like using thrusters, altering engine speeds on multi-engine setups, or adjusting sails to manipulate the course. However, these techniques are less precise and can be ineffective in certain situations, making the rudder an indispensable component of marine navigation. The consequences of rudder failure are substantial, emphasizing its importance, as discussed in this overview of rudder significance.
