6. Personality of Ship.—
In considering the maritime law, it is important to remember that one of its underlying ideas is that the ship has a personality of her own. In the common law, or law of the land, there is a similar notion in regard to corporations; they are legal persons quite apart from the stockholders who compose them. So the ship has a legal individuality quite apart from that of her owners. She may sue in the name of her owner and be sued in her own name. The principle has been expressed by the Supreme Court:
A ship is born when she is launched, and lives so long as her identity is preserved. Prior to her launching she is a mere congeries of wood and iron—an ordinary piece of personal property—as distinctly a land structure as a house, and subject only to mechanics' liens created by a state law and enforceable in the state courts. In the baptism of launching she receives her name, and from the moment her keel touches the water she is transformed, and becomes a subject of admiralty jurisdiction. She acquires a personality of her own; becomes competent to contract, and is individually liable for her obligations, upon which she may sue in the name of her owner, and be sued in her own name. Her owner's agents may not be her agents, and her agents may not be her owner's agents. She is capable, too, of committing a tort, and is responsible in damages therefor. She may also become a quasi bankrupt; may be sold for the payment of her debts, and thereby receive a complete discharge from all prior liens, with liberty to begin a new life, contract further obligations, and perhaps be subjected to a second sale.
