The ARG system (Anti Rolling Gyros)

The ARG system (Anti Rolling Gyros), produced by Mitsubishi Heavy Industries, Ltd. (MHI), applies the operating principle of a control moment gyro (CMG), and is able to reduce boat rolling by more than 50%, for a more comfortable ride.

In essence, an ARG consists of a flywheel mounted on a gimbal and a motor putting in rotation the flywheel. Based on the same principle as that of a spinning gyroscope, the high-speed rotation of the flywheel produces force to counter the rolling motion of the vesse.

Although other devices that reduce rolling during cruising exist - fin stabilizers, for example - the ARG is the first system in the world capable of reducing rolling of a small boat even at anchor or when trolling. Finally, thanks to their extreme quietness, one can even activate ARG stabilizers at night without disturbing the shipowners and guests’ sleep.
