“Please effect 2,000 l . upon 5–6ths of the ship; the whole valued at 10,000 l ., per the Imperial, Thomas Marshall, at and from Liverpool to the coast of Africa and the African islands, during her stay and trade there, and from thence back to Liverpool, with liberty to exchange goods with other ships; at 6 l. per cent .

“Having resumed consideration of these conjoined processes, and advised the proof, productions, and debate, finds, that the privilege specified in the different policies of insurance, with liberty to exchange goods with any other ship or ships; or, with liberty to exchange goods with every vessel or vessels; does not , in common language, and without a peculiar conventional meaning, import a liberty to exchange goods, without regard to observing any proportion in bulk or value between the goods so exchanged; and still less , that the exchange may be so conducted by the vessels insured, as that it should retard the completing of her own cargo, and protract her own stay in the seas where it is to be completed, and in order to hasten the accomplishment of the voyage of other vessels, or another vessel, and her or their speedy dispatch with a competent cargo; and as the risks of sea hazard are increased beyond an arithmetical proportion, by the prolongation of the adventure, particularly in the business of a coasting voyage to complete a cargo, so enlarged a construction of the privilege is more difficult to be entertained, where nothing appears in the rate of insurance stipulated between the parties, indicating that such an eventual augmentation of risk was in contemplation: finds it nevertheless proved, that the enlarged construction of the privilege contended for by the Chargers, was adopted by a great number of the dealers and underwriters in the African trade, but not uniformly in point of extent of such construction, and not universally in any extent even at Liverpool :
“I certainly proceeded, in pronouncing the interlocutor, on the opinion, that the long stay of the Imperial, for so many months on the coast, was not at all accounted for, but from her sub-serviency to the George; and if the Chargers reclaim, this seems to me essential to be obviated.”
