Book excerpt: London and the Southeast of England is home to an alternative community of people called 'boaters'; individuals and families who live on narrowboats, cruisers and barges, along a network of canals and rivers. Many of these people move from place to place every two weeks due to mooring rules and form itinerant communities in the heart of some of the UK’s most built-up and expensive urban spaces. Boaters of London is an ethnography that delves into the process of becoming a boater, adopting an alternative lifestyle on the water and the political impact that this travelling population has on the state.
