What will happen if propeller of a ship break down or lost in the sea?

If a ship's propeller breaks down or is lost at sea, the vessel will lose its ability to maneuver and maintain speed, rendering it effectively adrift. The crew would need to deploy emergency protocols, such as using anchors to stabilize the ship or calling for assistance. Without propulsion, the ship may drift with currents and winds, potentially leading to collisions or grounding. In such situations, timely communication with maritime authorities is crucial for rescue operations.
