What is the primary purpose of a deadman’s switch on a boat?

The primary purpose of a deadman’s switch on a boat is to shut off the engine if the operator is thrown overboard. This safety feature is crucial because it prevents the boat from operating uncontrollably, which could pose a significant danger to the person in the water and anyone else nearby. When the operator is in control, the switch remains engaged, allowing the engine to function normally. However, if the operator falls or is thrown from the boat, the switch is disengaged, leading to an immediate shutdown of the engine. This design helps prevent accidents and injuries that could occur if the vessel continues to move without a steering operator.

The other options do not align with the function of a deadman’s switch; they focus on features unrelated to safety in scenarios where the operator is incapacitated or absent.
