Floating platform apparatus for wave power conversion, consisting of armatures with buoyant, semi-submersible segments pivotally joined to an interlinking segment for controllable, repeated transitions of the primary axis of the entire apparatus from the extended horizontal posture to the vertical posture while still permitting the armature to oscillate in two planes within a restrictive collar, the oscillations thrusting fluid pumps to drive a generator to derive electrical power from the motion. Environmental sensing causes adjustment of the length of the armature and of the variably fixed facing angle of the collar within the interlinking segment in order to harness and manage forces impinging on the system. Dynamic harmonic tuning and resonance management are achieved by varying armature length through employment of telescoping, nested elements in the armatures.
