Two types of people may be injured while aboard a cruise ship, paying passengers or crew members (staff of the cruise ship). Both types of injured persons may have different legal claims. The claims depend on the injuries sustained, the persons who may be liable for the injuries and the law applicable to the claims. Some examples of possible claims are negligence, medical negligence or assault. Generally, the ship owners will be liable for any injuries of passengers or crew members, since the owners have a duty to provide a safe environment and protect persons aboard their ship from known (or foreseeable) dangers.
