Abstract
A flexible paddle wheel structure comprises a pair of axially spaced wheels, having flexible rims, such as, for example, pneumatic tires, with pairs of radially spaced, transverse, flexible members extending between, and attached to, the rims. A flexible membrane extends between the transverse members in each pair to form a flexible paddle. The wheels can tilt relative to each other and the whole structure can be arranged to be lifted and lowered.
