History

Iris was built sometime between 1895 and 1928 by J.Wilesmith & Co. of Worcester, and was used until about 50 years ago as a motor-driven ferry on the River Severn at Kepax, Worcester. It is not known whether steam plant was ever fitted. She lay derelict for many years until rescued by Michael Lamb of Worcester, who fitted a new oak keel and ribs. Restoration was continued by Malcolm Richards 2006 onward, but is not yet complete because of pressure of time and advancing age. Further information in "Funnel" Autumn 2017.
