Other than a PFD what two things abord a personal watercraft?

Other than a personal flotation device (PFD), two essential items to have aboard a personal watercraft are a fire extinguisher and a sound-producing device, such as a whistle or horn. The fire extinguisher is crucial for safety in case of fire, while the sound-producing device is necessary for signaling and communication, especially in busy waterways. Additionally, a first aid kit is also recommended for addressing any minor injuries.
