5. Liabilities of Underwriters.—
The insurers are ordinarily strangers to the ship as far as concerns any authority to instruct the master or incur obligations on her account. Only in case of an abandonment of the vessel to them, when the loss is total or constructively total, and when they have accepted such an abandonment, does such authority arise. An abandonment when properly made, or accepted, vests the property in the underwriter and the master then becomes his agent. The underwriter is then the real owner and has all an owner's liabilities and limitations. There is, however, a very large intermediate class of disasters where the underwriters decline an abandonment and yet take possession of the ship and cargo for the purpose of rescue and repair. Large expenses are thus created for which the damaged ship and cargo may be adequate security. The underwriters are personally liable, in the absence of special contract, for the contracts of their agents, although the nature of the business is such that it is often a practical difficulty to ascertain who were the insurers actually making the engagements and what was the real authority of those assuming to represent them. These questions are usually not raised during the exigencies of salvage operations but may become important when the work is unsuccessful and the expenses are unpaid.
