Ship stabilizers such as rotors and active fins are highly efficient for reducing a ships’ roll and rolling motion. While fixed fins and passive antiroll tanks may be able to stabilize larger ships to a certain degree, active systems are far more sophisticated and effective, especially at anchor.
Contrary to popular belief, stabilizers aren’t most critical in rough seas and in high waves, but it’s zero or slower speeds that require the most effective stabilization. When a ship’s speed increases, water flows more rapidly along the hull and control surfaces generating more hydrodynamic lift and force. At Zero Speed™ however, active fins or rotors are required to stabilize the vessel without the dynamic stability of being underway. Quantum pioneered Zero Speed™ Technology in 2000 and continues to offer it across all current systems, maintaining a performance edge over most other stabilizer solutions.
