Drive assembly

A drive assembly arranged to transfer wave energy to an energy converter, the drive assembly comprising,

• a float;
• a lever arm coupled to the float, the lever arm being movable between a first position and a second position to define a working stroke;
• wherein the lever arm is coupled to the energy converter to transfer energy from the float to the energy converter;
• wherein the float is arranged to move the lever arm between the first position and the second position;
• wherein the first position and the second position define distal end points of the working stroke;
• the working stroke being configured to drive the energy converter;
• wherein the drive assembly is arranged to be mounted onto a buoyant platform, such that the float is positioned at a height relative to an upper surface of the buoyant platform;
• and
• wherein the lever arm is arranged to move to adjust the height between an in-use height and a docked height, the in-use height being greater than the docked height, wherein movement of the lever arm by the float occurs by way of rotation of the lever arm about a fulcrum to define a rotation arc or by way of flexion of at least a portion of the lever arm, wherein the movement occurs by flexion of the lever arm, and wherein the lever arm is arranged to store elastic potential energy in the range of 5 to 50 MJ in response to said movement by the float.
