For boats with inboard gasoline engines,
fuel vapor build-up

What can cause a boat to explode?

improper ventilation or the failure of the blower system prior to starting the engine of the watercraft
. It is important to use the ventilation before starting the engine of your boat because often the fuel vapors can settle in the engine compartment or bilges of the boat.
Why do boats explode after fueling?
Evaporating gasoline creates vapours or fumes that are heavier than air. These vapours settle to the bottom of the pleasure craft where they could explode if enclosed areas, such as the bilge,
are not ventilated properly to remove vapours
. This will help eliminate fuel vapours in the bilge. …
Can diesel boats explode?

What should you do if your boat turns over sinks or runs aground?
Use
the “Reach, Throw, Row, or Go” rescue technique

How long do you run the blower on a boat?
