Two people were flown to shock trauma after separate incidents Friday and Sunday.
Most recently, a Havre de Grace man was injured by injured by a boat propeller.
The 40-year-old man was at the City Yacht Basin at about 12:35 p.m. when he somehow got too close to a running boat, lacerating his leg between the knee and hip, Maryland Natural Resources Police Sgt. Brian Albert said.
Albert said the incident is still being investigated.
"There were a bunch of boats that were resting all together and it was pretty rough water," he said of the conditions at the time.
The man, who suffered non-life-threatening injuries, was expected to be in the hospital for four days, Albert said.
Maryland State Police and the Havre de Grace Ambulance Corps also responded to the incident.
A 48-year-old Edgewood woman was flown to shock trauma Friday night after she allegedly failed to yield the right-of-way at the intersection of Route 7 and Edgewood Road while making a left turn, according to David R. Hooper, with the Maryland State Police.
The woman was released the following day, Hooper added.
