Anti Rolling Gyro Stabilizers

Mitsubishi Antirolling Gyo 1 Mitsubishi Antirolling Gyro 2

The Tohmei (formerly Mitsubishi Heavy Industries) Anti-Rolling Gyro (ARG) stabilisers significantly reduce boat roll at anchor and trolling speeds. Gyro technology originally developed for space vehicles is utilised to create forces opposing vessel roll (view theory of operation). The ARG can be fitted to virtually any commercial or pleasure craft to enhance passenger comfort and reduce crew fatigue.
