Which item is typically NOT found in a boat's safety kit?

A reserve fuel tank is typically not found in a boat's safety kit, as safety kits are designed to provide essential supplies and equipment that ensure the safety and well-being of those on board during emergencies or unexpected situations.

Items such as a first aid kit are crucial for treating minor injuries, while flares serve as important signaling devices for attracting attention in case of emergencies. A whistle or air horn is another essential tool used to signal for help or alert others in close proximity. In contrast, a reserve fuel tank, while it may be beneficial for extending the boating trip, does not directly contribute to safety and emergency preparedness, making it less appropriate for inclusion in a safety kit.
