An apparatus for conversion of water wave energy comprising at least two members (1, 2) which are adapted to be at least partially submerged in the water and so interconnected (at 3) as to permit relative oscillating movements of the members. In order to obtain a maximum utilisation of the wave energy, the connecting means between the two members in a pair comprises a device (4, 5) adapted to lock the two members relatively to each other whereby the natural period of the combined two members (1, 2) is increased relatively to the average natural period of the waves. The locking device is operative until just before the wave motion reaches its greatest displacement and is then released so that member 1 moves rapidly relative to member 2. The locking device is re-engaged when the relative velocity of members 1 and 2 is a minimum. <IMAGE> |
