7.8 Jones Act Negligence or Unseaworthiness-Damages-Proof is the legal standard required to establish liability for an employer's negligence or an unseaworthy vessel in a personal injury claim brought by a seaman under the Jones Act. To prove negligence or seaworthiness under the Jones Act, a seaman must show that the employer was responsible for the vessel's condition and that the vessel was not reasonably fit for its intended use, and that the seaman was injured in the course of his or her employment. Different types of 7.8 Jones Act Negligence or Unseaworthiness-Damages-Proof include direct evidence or circumstantial evidence of negligence, such as the vessel's condition, the employer's knowledge of the vessel's condition, the seaman's qualifications, the availability of safety equipment, and the employer's adherence to safety protocols.
