The first tugs were built at the beginning of the nineteenth century because of the development of enclosed docks and the increase in size and power of sea-going vessels. Tugs were needed to assist ships to their berths and to navigate larger vessels into narrow waterways and tight docking areas. They are able to tow or push vessels and need to be highly manoeuvrable and powerful. It is thought that the first tugboat was the Charlotte Dundas, which was powered by a Watt engine and was employed towing barges on the Forth and Clyde Canal in Scotland in 1802. The early tugs were fitted with paddle wheels and these were later replaced by propeller driven vessels.This book by Ian Collard looks at various types of tugs employed around the British Isles assisting a variety of different types of ships in the major and some smaller ports around the coast. It is illustrated by previously unpublished photographs from the author's collection.
