The NAIAD MultiSea II stabilizer controller represents decades of experience in roll stabilization technology. This Three-Term (roll angle, rate and acceleration) system is specifically designed to provide maximum roll damping effectiveness while underway in seas from any direction (including following seas). It also senses and corrects list and rudder-induced heel. Specifically designed for use on yachts, the MultiSea II combines highly sensitive control with remarkably easy installation and operation.

Introduced less than two years ago, several hundred MultiSea control systems have been fitted with excellent results to yachts of every description.

The system's motion sensors give continuous input to the controller for closed-loop electro-hydraulic control and feedback allowing precise and fully proportional fin position management. The system automatically centers the fins below a pre-set low-speed point (eg. while maneuvering or moving astern) and above a pre-set high-speed point (if desired). It also features a Fin Control Curve, programmed into the system's micro-controller, to limit maximum fin angle as a function of vessel speed to avoid fin cavitation and drag. The Fin Control Curve can be easily customized to exactly fit the operating characteristics of any vessel. Other adjustments are easily made to optimize performance and to configure the system's logical parameters for specific applications.

The main control panel features illuminated bargraph-style fin position indicators, system control pushbuttons that light to indicate various system status conditions and system sensitivity control adjustments that allow the operator to fine tune system performance.

Additional control panels can be connected for operation from the flybridge, wing stations, engine room, etc. System alarms include explicit Low Oil Level and High Oil Temperature alarms and implicit alarms for Loss of Serial Data Link, Fins Not Centered, and others.
