Sewerboat  is part of a series of works which in different ways have dealt with the idea of the subterranean, or the underworld, often using industrial/urban forms and structures as a reference point.

Sewerboat is modelled of one of the 19th century technological innovations, a Parisian sewer cleaning device. The sculptural object suggests a technology that is no longer extant. The piece explores themes such as travel and mortality/death, in relation to superseded and current technology. It also focuses on the image of the horizon line and the Romantic idea of an Infinite space, as a popular motif and subject from the history of art.
