Fumes are heavier than air. Run the blower. You’re house furnace does too for the same reason.

It happened at the 15th street fisheries fuel dock, same canal as Southport and directly across from Pier 66 just inside the inlet.

Local news was showing a pontoon boat on fire, I couldn't understand how a pontoon blew up like that. Turns out the pontoon was docked directly south of the boat that blew up and debris caused the pontoon to burn also.
