An explosion would be caused by gasoline vapor being ignited by flame, spark, etc.

Gas fumes are heavier than air and will sink to the lowest level. Fumes need to be concentrated in order to produce a volatile mixture. It might have been as simple as fumes from the re-fueling traveling down into the bilge through a hatch and finding a spark or lit cigarette.

Sad way to go, but lucky that only that boat got engulfed.
