In regards to cruise ship injuries, ship captains and owners alike share the responsibility of providing their passengers with valid medical care. Passengers who are injured aboard ships do have to right to begin a lawsuit against the ship owner. Their lawsuit would be much like if they were on land and were wounded due to a third party's carelessness. It is left up to the passenger claiming negligence to prove that the ship is at fault. In the event that you or someone you know becomes injured on a cruise ship, be sure to get treatment as soon as possible, and contact a local maritime lawyer for further action.
