That in every contract of employment between the owner of a UK ship and its master or any seaman employed in the ship, there will be an implied obligation on the owner (1) that the owner, the master and every agent charged with loading the ship, preparing it for sea or sending it to sea must use all reasonable means to ensure the seaworthiness of the ship for the voyage at its commencement, and (2) that the ship will be kept in a seaworthy condition for the voyage during the voyage. This obligation cannot be contracted out of (e. g. by a contradictory term in the crew agreement).
