In this paper a particular type of wave energy converter, namely EDS (Energy Double System) is presented. It is a two-body point absorber composed by a heaving float and a surging paddle, mounted on the same structure and aligned along the wave propagation direction. The system is designed for working in the breaker zone, where waves close to breaking can generate a considerable surging force on the paddle.

A scale EDS model has been built and tested in the wave flume of the Hydraulics Laboratory of the Politecnico di Milano. The power absorbed by the system, varying its configuration, position and wave, has been measured, and interesting efficiencies have been found.
