The
small single-screw diesel tug Charles Edward was built in 1958, and was
one of a large fleet of tugs operated by the Port of London Authority,
and smaller towage companies, before the nature of shipping on the River
Thames was changed forever by the introduction of containerisation. This
created new ports like Tilbury that were closer to the open sea, and could
handle much larger ships. Before cargoes moved down river in the sixties
and seventies, many small tugs like this one could always be seen in and
around the London docks. They were employed mainly for towing unpowered
barges or lighters, and because these vessels almost always worked in
sheltered waters, one typical feature of this type of small tug is the
unusually low height of the bulwarks. This makes quite a simple tug with
few fittings, and the hull has also been used to model a number of other
small tugs and harbour and canal boats which tend to share a very similar
basic hull form.
