Around 3 p.m., a small boat was getting fuel outside the bait and tackle shop near the Cortez Bridge.
Fumes from the fuel caused an explosion, injuring the one person on board and damaging the boat, according to Tom Sousa, chief of West Manatee Fire District.
When firefighters arrived, there were no flames; the fumes quickly burned off in the explosion, Sousa said. The Coast Guard was called to investigate the incident.
