Who is responsible for the actions of passengers on a boat?

The boat operator is responsible for the actions of passengers on a boat because they have a legal obligation to ensure the safety and compliance of everyone on board. This responsibility includes ensuring that passengers follow safety regulations, such as wearing life jackets when required and not engaging in reckless behavior that could endanger themselves or others.

The boat operator oversees the safe operation of the vessel and maintains control in potentially hazardous situations. In the case of any incidents or emergencies, the operator must be prepared to manage the situation effectively, which often requires directing passengers on how to act appropriately to minimize risks.

While passengers should certainly take personal responsibility for their actions, the operator's primary role is to guide and ensure the safety of all individuals aboard. The other options listed, including authority figures like the harbor master or local authorities, do not hold the same level of direct oversight and responsibility for the behavior of passengers on a specific boat.
