The document presents a model for how situational awareness factors influence decisions about wearing life jackets while boating. It identifies dynamic risk factors like weather, water conditions, and activities that could change during a boat trip. It also identifies static risk factors like boat size, regulations, and experience that do not change. These factors along with boat type contribute to situational awareness of risks, which influences the perceived risks of capsizing or falling overboard and the perceived consequences of entering the water, ultimately impacting the decision to wear a life jacket.
