How does the Seakeeper gyro compare to fin-based roll stabilization systems?
Because of there drag at speed, fin systems are not suitable for planing hulls. Fin systems are speed dependent, always balancing fin size with projected cruising speed, so as to create minimum drag for desired performance. The result is that at zero speed they have no effect (except on very large yachts with long roll periods), and at less than cruising speed, performance drops off sharply. In contrast, the Seakeeper Gyro remains fully effective from zero speed right through planing speeds, including the roughest conditions when the boat has to slow down. Because the gyro requires no protrusions from the hull, it is not subject to snagging seaweed, damage from grounding, or impact from floating debris.
