What is the function of interlocks on a boat?

Interlocks on a boat serve an important safety function by automatically turning off the engine or triggering an alarm in specific situations. This safety feature is designed to help prevent accidents and injuries that could occur if the boat were to become unsafe. For example, if a person falls overboard or if the operator is not in a safe position to control the boat, the interlock system can immediately engage to shut off the engine, reducing the risk of further accidents.

The primary goal of interlocks is to enhance safety rather than to affect performance characteristics like speed, buoyancy, or fuel efficiency. While those aspects may be important in other contexts, the key function of interlocks focuses on protecting individuals onboard and ensuring that the vessel operates safely under varying circumstances.
