The Rolls-Royce stabilisation at rest (SAR) system - is a simple modification of the Aquarius retractable stabiliser design. It represents true simplicity in design - to deliver the best in performance, particularly for large yachts.
At the heart of the system is a control system that senses the start of any roll. When the vessel is at rest, the fins are ‘active’ and oscillate at the maximum angle to counteract the wave motion. When the ship is underway, the system returns the fins to their normal degree of movement, using the lift forces generated by the ship’s forward speed to damp roll motion.
The smaller Aquarius 25 (>3.5m²) and the larger Aquarius 50 (>8m²) are available in the stabilisation at rest configuration.
