Step-by-step explanation:
Wearing a personal flotation device (PFD) or lifejacket when on board a boat is important for safety. These devices are designed to help keep you afloat in case of an accident or if you fall overboard. They provide buoyancy and assist in keeping your head above water, which reduces the risk of drowning. Additionally, lifejackets are often brightly colored and have reflective strips, making it easier for rescuers to locate you in the water. It is crucial to wear a PFD or lifejacket at all times when on a boat, especially if you are not a strong swimmer or in situations where there may be rough waters or strong currents.
