Carrier liability for unmanned ships

open access: yes, 2019
A person whose business it is to carry goods by sea must do so with a seaworthy ship. ‘Seaworthiness’ is a very extensive concept, not limited to the features of the physical ship herself, but also extending to the qualities of the crew. The obligation is only to provide a crew that is reasonably suited for the intended use or service.
