Large scale dredging of the waterway between Port Glasgow near [[Greenock]] and Glasgow itself during the 18th century brought ocean-going vessels to Glasgow, and made the river a conduit for much the industrial produce of south-western Scotland on its way to the New World, and the area the site of a booming ship-building industry.
