Active Fin Stabilizers Models 575, 621, 720, 820 & 925 Roll Reduction While Cruising and At Rest (Stabilization at Anchor) The industry standard for superior performance, quality, reliability, long‐term support and overall value. With more systems in service than all other brands combined, Naiad’s product designs are a refined evolution earned from real‐life experience, analysis, and constant development. Install Naiad, Instill Confidence™ Naiad Stabilizers are the equipment of choice installed in thousands of vessels in demanding commercial and military ship applications as well as luxury yachts of all sizes. Fin Actuator Assembly Features Highest quality materials and workmanship. Major components machined in‐house to US military standards and concurrently produced alongside aerospace machined parts. Industry first heavy‐duty tapered roller bearing construction, fully pre‐assembled and sealed at the Naiad factory for easy installation. Compare to inexpensive and wear‐prone plain bearings/bushings. Greased for life, no annual main bearing maintenance required. Triple lower shaft seals incased in an easily accessible housing. Industry best double spherical Rod End bearings. Roller bearings (not bushings) at all pivoting locations. Proven hydrodynamically‐efficient foil section designs. Tip fences proportionately sized and validated for performance. Advanced composite fin construction is galvanically inert and features an encapsulated stainless steel insert with precision machined self‐locking keyless taper. Steel fins optional. Keyless taper allows freedom to install the NAIAD Assembly in any 360° orientation to simplify installation and maximize accessibility, plus allows the fins to be aligned and realigned in any desired position to suit hull flow lines. Hydraulic taper lock. First choice among discriminating yacht owners and ship builders throughout the world.

Digital Control System Advanced & proven fully proportional automatic Angle‐Velocity‐Acceleration (AVA™) closed loop control system for maximum roll reduction performance in any seaway with minimum drag. Resonant roll reduction typically 90%. Static heel correction. Sensitivity adjustment. Automatic fin limiting and centering. DATUM™ Adaptive Technology self‐tunes to optimize performance. Enhanced course‐keeping, reduced rudder drag typically improves overall destination time and fuel efficiency. DATUM™ is the world’s first purely digital fin stabilizer control system operating on a CANbus ...
