Other than a PFD, what two things must be aboard every personal watercraft?

Every personal watercraft, commonly known as a jet ski, is required to have specific safety equipment on board to ensure the safety of the operator and passengers. The correct answer highlights the necessity for a fire extinguisher and emergency signaling devices.

A fire extinguisher is vital because personal watercraft can be prone to fires due to the fuel and mechanical components. Having a fire extinguisher on board allows operators to quickly address fire incidents, enhancing safety significantly.

Emergency signaling devices, such as flares or whistles, are important for ensuring that individuals can signal for help in case of an emergency or distress situation. They assist in increasing visibility and letting other boaters or rescue personnel know that someone is in need of assistance.

By including both a fire extinguisher and emergency signaling devices, this choice emphasizes the commitment to safety and preparedness on the water, which is crucial for all boating activities.
