Water is not recommended for a boat fire extinguisher primarily because it can be ineffective or even exacerbate certain types of fires. For instance, water is harmful when used on fires involving flammable liquids, such as gasoline or oil. When water is applied to a burning fuel, it can cause the flames to spread, as the water can turn to steam and potentially splash the burning liquid, leading to a larger fire. Additionally, using water on electrical fires can lead to electrocution, as water conducts electricity.

In contrast, foam, dry chemical, and carbon dioxide are designed for use in various fire scenarios on boats. Foam extinguishers are effective against flammable liquid fires, dry chemical extinguishers are versatile and can be used on multiple fire types, and carbon dioxide extinguishers are particularly useful for electrical fires and are safe to use without leaving a residue. Thus, using water in small, confined, and risk-charged environments like boats poses significant safety hazards.
