Gyroscopic stabilization works on a simple principle: a heavy flywheel spins at high speed inside a vacuum-sealed housing, and when the boat rolls, the unit produces a counteracting torque. Seakeeper describes the flywheel spinning at up to 9,750 rpm inside vacuum encapsulation, with computerized active control optimizing the gyro torque.
The Seakeeper 6 was introduced in 2017 as the model sized for 40 to 49 foot vessels, up to roughly 20 tons, with a stated roll reduction of up to 95 percent. Launch reporting noted it was 40 percent smaller than the original M7000 model while delivering comparable stabilization, with 25 percent lower power draw.
The unit runs on DC battery power and installs below deck. The electronics suite introduced with the model includes a touchscreen display with NMEA and Ethernet connectivity for helm control and monitoring.
