1979 - Launch of Sullage Lighter SL 04

The giant 240 ton crane on the Promontory was used to lift the latest new construction into the water, the 100 ton sullage lighter SL04. She is one of a pair the other being 03 is also nearing completion. They were built in six segments in the Heavy Plate Shop and transported to the Promontory were shipwrights assembled the craft on building blocks. Being a dumb lighter there was little fitting out to be done.
