They marked the beginning of increased activity by Scott & Co., particularly with respect to large, ocean-going ships.

Between 1988 and 1997, the Cartsburn and Cartsdyke shipyards were gradually demolished and redeveloped as insurance offices, computer warehouses and fast food restaurants.

[5] In 2011, Greenock's McLean Museum and Art Gallery celebrated the tercentenary of Scotts' foundation.

[6] Notable vessels built included the early Royal Mail Steam Packet Company liners Clyde, Dee, Solway and Tweed in 1841, SS Thetis of 1857, which John Scott (1830–1903) financed himself to test his theory about high pressure steam in the compound engine, which worked at about 120 lbf/in2 in Thetis,[7] the early tanker Narragannsett in 1903, the barque Archibald Russell, the British S-class submarines, in 1914, the cruiser HMS Glasgow in 1937, and the drilling ship Ben Ocean Lancer in 1977.

Scotts Assistant Manager James Richardson devised an early "Snorkel" for submarines, for which they were granted British Patent No.106330 of 1917.

[10][11] Pictures of some Scotts-built vessels were painted by the Greenock marine artist William Clark.
