The Vulcan, launched in 1819, was the first all iron-hulled vessel (boat) to be built. It was designed as a horse-drawn passenger barge for use on the Scottish canals..In 1816, the Forth and Clyde Canal Company, which had earlier successfully adapted new technology to shipbuilding with the Charlotte Dundas, authorized the development of an all-iron ship, and they quickly settled upon building a canal barge. In 1818, Thomas Wilson (1781 1873), was hired as the shipwright. The barge was to be 20 meters (66.5 ft.) long and narrow enough for the canal. The design called for iron sectionals to be riveted together with covering plates. Two blacksmiths were hired to construct the parts.
