Gasoline fumes on a boat are most likely to accumulate in enclosed spaces, particularly in the bilge, engine compartments, and other low-lying areas where air circulation is limited. These fumes can also collect around fuel tanks and in the vicinity of fuel vents. Proper ventilation and regular maintenance are essential to prevent the buildup of flammable vapors in these areas.
