What should you do if propulsion or steering fails while underway?

When propulsion or steering fails while you are underway, the most immediate and sensible course of action is to signal for help. This step is essential because it alerts other boaters or maritime authorities that you are in a situation requiring assistance. Promptly notifying others ensures that help can arrive quickly, minimizing the risks associated with being adrift, such as collisions or drifting into hazardous areas.

While trying to fix the issue immediately might seem logical, it could lead to more distractions and complications, especially if you're in a busy boating area or facing strong currents. Using flotation devices is crucial in case of an emergency, but it does not directly address the immediate need for assistance due to a loss of propulsion or steering. Remaining in a stationary position could be dangerous if other vessels are approaching or if you're in a current, as it could lead to collisions or further complications.

Thus, signaling for help is the most prudent action to take when you find yourself in this situation.
