While no one was hurt in the fire, a Maryland Natural Resources Police officer and three others were injured in a crash in Severna Park as the officer was driving to the rescue site.
Natural Resources Police were called to Stoney Creek at 5:26 p.m., spokeswoman Candy Thomson said. Responders found a 20-foot power boat with a couple and their child on board with an engine fire and floating toward White Rocks, a rocky outcropping in the Patapsco River off the mouth of Stony Creek.
Thomson said firefighters from Baltimore City and Anne Arundel County were able to put out the fire.
Police towed the damaged vessel to shore. No one on board was injured, and no citations were issued.
