What is the purpose of sniffing the bilge and engine compartment after fueling?

The purpose of sniffing the bilge and engine compartment after fueling is primarily to check for fuel vapors. This step is crucial for safety because the presence of fuel vapors indicates a potential leak or spillage from the fueling process. These vapors can be highly flammable and pose a serious risk of fire or explosion if they accumulate, especially in enclosed spaces. By sniffing these areas, a boater can quickly identify any issues and take corrective action, enhancing overall safety while operating the vessel.

While being aware of oil leaks, water accumulation, or ensuring that no passengers are trapped is important for the safe operation of a boat, these concerns are not directly related to the immediate risks associated with fueling and the dangers posed by fuel vapors.
