Built for the Leith, Hull and Hamburg Steam Packet Co., owned by James Curry of Leith, "Y" was employed, as were most of their lighters, on the transhipment of cargo along the Monklands and Forth and Clyde Canals between Port Dundas in Glasgow and the ports on the Firth of Forth. Sold in the early 1900s to Smith & Watt of Dunfermline. On 9th May 1928 when laden with a cargo of esparto grass she caught fire in the Forth of Forth and was beached at St David's Bay. Contemporary reports state that she was expected to be declared a constructive total loss but I have to date not been able to ascertain what her utimate fate was, except that her registry entry was closed in 1929..
I've identified a total of 13 of these alphabetically named steam lighters owned by LHHSP Co. There are others in the sequence but these were either sailing vessels or dumb lighters and so are excluded.
