Emergency situations require advance planning. Think about what to do if someone falls overboard or if there is a fire, breakdown or collision. Practice putting on your life jacket in the water and throwing a type IV personal flotation device. Know the various distress signals as slowly and repeatedly raising and lowering your outstretched arms. If your boat capsizes, it will usually float.
Weather is unpredictable.
Watch for changing conditions. File a float plan. Tell someone where you are going and when you will return. It could save your life if there is an accident. Learn boating safety.
