Able to actively stabilize most vessels with displacements up to 90 tons, the M21000A is the perfect choice for discerning owners wanting a complete stabilization system that works equally well at zero-speed and at anchor and also speed while underway. For larger vessels, multiple units can be installed to achieve the desired stability stabili characteristics. Performance Resonant boat roll is the most disorienting contrast with dry land experience and the least desirable motion on a boat. Uncomfortable, tiring, and probably the greatest cause of seasickness, it has been an unavoidable price to pay for many for the pleasure of being on the water. Employing the principles of gyro-dynamics, Seakeeper vacuum-sealed gyro stabilizers exert a powerful righting dynamics, exer torque that virtually eliminates boat roll without any need for drag drag-producing or damage mage-prone protrusions or appendages from the hull. Seakeeper’s unique state-of-the-art motion control system actively regulates the hydraulic braking system to ensure the anti anti-roll torque is maximized for all hull designs and for the everever changing operating and sea conditions.

Electrical The builder is responsible for supplying 208-230 VAC (+/- 10%), 50/60 Hz, single phase power on a 30 Amp service to the Motor Drive Box and 24 VDC on a 10 Amp service to the Control Box. Cooling The Gyro bearings and Motor Drive Box are cooled by a closed glycol cooling loop that incorporates a sea water heat exchanger. The builder is responsible for providing 15.1 lpm raw water at ambient sea temperature and 6.9 Bar maximum pressure to this heat exchanger. The ambient air temperature in the compartment in which the Gyro and Motor Drive Box are mounted should not exceed 50 C. Loads...
