Which of the following is NOT included in the required contents of a boat as per the Marine Safety Act?

The Marine Safety Act outlines specific safety equipment and items that must be included on a boat to ensure the safety of all passengers and crew. Among the items listed, a navigational chart is not mandated as a required content for safety compliance under the act. This is because the focus of the regulations is primarily on immediate safety measures, such as fire extinguishers to combat potential fire hazards, personal flotation devices to protect individuals in case of accidents, and proper running lights to ensure visibility and adherence to navigation rules during low-light conditions.

While navigational charts are certainly important for safe boating and navigation, they do not fall under the category of immediate safety equipment that must be present aboard the vessel as defined by the Marine Safety Act. Therefore, the correct choice highlights the distinction between essential safety gear and supplementary navigational aids that enhance overall boating safety but are not legally required.
