Paddle-steamers - and trips doon the watter - were a particular feature of life in Glasgow. From Wikipedia;

The Charlotte Dundas was the first practical steamboat, in that it demonstrated the practicality of steam power for ships. The first sailing was on the canal in Glasgow on 4 January 1803, with Lord Dundas and a few of his relatives and friends on board.

Henry Bell's PS Comet of 1812 inaugurated a passenger service along the River Clyde in Scotland. [Comet] started a rapid expansion of steam services on the Firth of Clyde, and within four years a steamer service was in operation on the inland Loch Lomond.

On the Clyde itself, within ten years of Comet's start in 1812 there were nearly fifty steamers, and services had started across the Irish Sea to Belfast and on many British estuaries. By 1900 there were over 300 Clyde steamers.
