Application Seakeeper’s new M8000 gyro is a more powerful version of the original Model 7000 unit. Designed for easier installation and higher performance, it actively stabilizes vessels with displacements up to 35 tons. It is the perfect choice for discerning owners wanting a complete stabilization system that works equally well at zero-speed and at anchor and also while underway. For larger vessels, multiple units can be installed to achieve the desired stability characteristics or the new M21000 can be utilized. 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 torque that virtually eliminates boat roll without any need for drag-producing or damage-prone protrusions or appendages from the hull. Seakeeper’s unique stateof-the-art motion control system actively regulates the hydraulic braking system to ensure the anti-roll torque is maximized for all hull designs and for the ever-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 60 C. Loads...
