s capacity, and the largest ones can carry up to 300 TEU containers (empties). Lighters are usually not fitted with engines but are towed or pushed by tugboats. In 2007, midstream operators handled about 2 million TEUs and 5 million TEUs were transported as river trade cargo which are heavily dependent on lighters. In the UK, some older lighters have been converted into houseboats (for living on the river). As they lack engine rooms and gearbox, shaft or propellers, this means maximum usage of the hull space into housespace. As they have no propulsion methods, they are towed from conversion sites to permanent or semi-permanent mooring sites. They have macerators to deal with toilet waste.

. Lighter tugs—or simply "lighters"—are designed for towing lighter barges. As such, they are smaller than traditional harbour tugs and lack the power or equipment to handle large ships.
