Hydrostatic pressure of a passing wave crest causes collapse of flexible bags pumping air from the bags via a non-return valve into a high pressure air conduit 14a, 14b. The bags are re-inflated in the wave trough from a low pressure air conduit 13. One or more turbines 19, 21 are driven by air flow from the high to the low pressure air conduits. By controlling the restriction to air flow passing through the turbine(s) power extraction is optimized. By providing separately adjustable air flow circuits for the bow end and the stern end, differential control of the flow restriction in the two circuits provides control over pitching of the device.
