Conditions in these floating jails were untenable. The hulks were overcrowded and cramped. A hulk could be the same size as six buses placed end to end. On board each hulk there were around 300 convicts. Disease was rife on board and between 1776 and 1795, around 2,000 of the 6,000 convicts held on hulks died from diseases such as typhoid and cholera.
The convicts were not fed very well. The people in charge wanted to keep costs as low as possible. The daily diet was often made up of ox-cheek, made into soup, pease, bread or biscuits - and the biscuits were often mouldy. Tobacco was supplied as part of their ration or as a reward for good behaviour. All convicts rose at dawn and worked for up to ten hours a day having been sentenced to hard labour whilst in the hulks.
Although the hulks were supposed to be transitional, with convicts subsequently sent to the colonies, it is known that many convicts served their sentence without leaving English prisons or the hulks. The number of people being sentenced to transportation was high during the eighteenth century but the space in prisons and hulks available in Britain meant that some convicts remained in the county jails. During the later periods, the number of people being transported overseas declined significantly due to a variety of factors.
The main prison hulks were:
- HMS LEVIATHAN - Portsmouth
- HMS YORK - Gosport
- HMS HARDY - Tipnor
- HMS CAPTIVITY - Devonport
- HMS RETRIBUTION - Sheerness
- HMS CUMBERLAND - Chatham
- HMS EURALUS - Chatham
- HMS JUSTITIA - Woolwich
- HMS GANYMEDE - Woolwich
- HMS DISCOVERY - Deptford
There were many earlier hulks moored in England, Bermuda and Gibraltar.
