Hi Jim

The AMSTERDAM (Official No.78569) was an iron-hulled 806-ton British steam cargo vessel that measured: 66.75m by length, an 8.83m-beam and a 4.57m-draught.
Cunliffe & Dunlop, at Inch Yard, Port Glasgow built and completed her as Yard No.129 in February 1878; she was launched as the AVON in December 1877 for W. Sloan & Co., Glasgow. The single iron propeller was powered by a 2-cylinder compound steam engine that used one boiler. The shipbuilders manufactured the machinery.
In 1903, she was renamed AMSTERDAM by James Rankine & Son Ltd., who also owned her at the time of loss.
