Seakeeper 4

Vacuum-encapsulated gyroscopic anti-roll stabilizer for boats of approx. 38' - 44', with 4,000 N-M-S angular momentum at max rated speed.

Description

The Seakeeper 4 is a gyroscopic stabilizer that counteracts boat roll at rest and underway. It runs on DC power for boats without a generator and fits anywhere the Seakeeper 3 fits, making it an upgrade option for existing installations.

Inside a vacuum encapsulation the flywheel spins at up to 8,250 RPM. When the boat rolls, the gyro tilts fore and aft (precesses), producing gyroscopic torque to port and starboard that counteracts the roll.
