A wave energy converter (100) has a top-section (10) and a column (20) with a turbine section (140) containing a water turbine. The top-section (10) has rotational symmetry about a z-axis and a wave driven displacement pump (110) able to pump water to a design height H over an average sea level into a reservoir (119). A two-axis gimbal (160) connects the top- section (10) with the column (20) such that the top-section becomes tillable relative to the column (20), which is kept vertical during operation. Water leaves the reservoir (119) through the water turbine. An eductor section (130) adds a water flow to the flow from the reservoir (119) due to the Venturi effect. This reduces the need for water from the reservoir (119) required to produce an electrical power P.
