Camelavessel

Camel, a vessel, generally of iron or steel, formed of two parts, and designed for raising a ship out, or partially out, of the water. One part is affixed to each side of the ship, and the camel is then pumped dry. Camels are in some places used for raising ships sufficiently to enable them to pass river bars. They were long so employed at the mouth of the Y in Holland, and between St. Petersburg and Cronstadt; but, as a rule, dredging operations and the making of canals have of late caused them to be dispensed with.
