Abstract: Dynamic tuning of the oscillating buoyant body of a wave energy converter over a range of periods that characterize energetic swell is achieved by controlling the ratio of total mass moment of inertia to restoring force and by controlling wave bridging. Mass is varied by locking and unlocking neutrally buoyant masses or by trapping and releasing seawater. For surging, water-plane area is forcibly varied. For rotational variants of heaving and surging and for pitching, the radius of gyration is varied. Invariant mass is reduced by using materials and structures with high ratios of strength to weight. Invariant added mass is reduced by streamlining, by constant radius body profiles and by keeping moving structures out of the water. Added mass is varied by using variable angle fins. Control of wave bridging, for a pitching body, including a wave following device, is by locking and unlocking serial segments of the buoyant body.
