The paddle tug Clyde served the river for a commendable 61 years before being replaced by a screw-driven steam tug of the same name from the Ailsa shipyard at Troon in 1912. The old Clyde was scrapped at that time but Andrew Brown's son, William, arranged for the engines designed by his father to be taken out and presented them to the Burgh of Renfrew, in memory of his father, who had contributed much to the town's prosperity and well-being. The legend on the plate reads:
"The Engines of the TUG 'CLYDE'
Constructed for the CLYDE NAVIGATION TRUST
MESSRS A & J INGLIS, GLASGOW, 1851
The Late ANDREW BROWN ESQ, Provost of Renfrew for 15 Years
Presented to the Burgh of Renfrew
By WILLIAM BROWN ESQ M.I.C.E
In Memory of His Father"
At the same time that he was designing these engines Andrew Brown designed and built two pairs of geared beam engines for the first screw steamer to run between Leith and London and a three-cylinder engine of 3000 ihp fitted with outside slide valves steam starting gear and a built-up crankshaft, all of these features being 'ahead of their time'. While with Inglis he also had his first experience with dredging plant and it was in this area that Andrew Brown was to make his principal mark on the world of marine engineering.
