What is the MC² Quick Gyro? The MC² Quick Gyro is an advanced gyroscopic stabiliser designed and built in Italy by Quick, a global leader in marine equipment. Unlike traditional stabilisers that use external fins or flaps, the MC² Gyro relies on an internal high-speed flywheel housed inside a compact casing. As the flywheel spins, it generates a stabilising torque that counteracts the rolling motion of the vessel. The result is dramatic: up to 95% reduction in roll, whether you’re moored, anchored, or underway.
