REVOLUTIONIZING STABILITY AT SEA
The Technology Behind the World’s Leading Marine Stabilization System
At the heart of every Seakeeper lies a precision-engineered high-speed flywheel enclosed within a vacuum-sealed sphere. This advanced gyroscopic technology actively counteracts boat roll by generating powerful stabilizing forces, delivering an unmatched level of comfort and control on the water.
Powered by sophisticated sensors, intelligent control systems, and aerospace-inspired engineering, Seakeeper continuously monitors vessel movement and responds instantly to changing sea conditions.
The result is a smoother ride, reduced fatigue, increased safety, and a more enjoyable boating experience for everyone onboard.
Advanced Engineering. Intelligent Stabilization. Unrivaled Comfort.
The Flywheel
The flywheel spins at speeds up to 557 miles per hour generating enough force to... well, stop a boat from rolling.
Vacuum Sealed
Seakeeper’s vacuum encapsulation enables the flywheel to spin roughly three times faster, cuts flywheel weight by two-thirds, and halves power requirements. Because the critical components (flywheel, bearings, and motor) are sealed in a vacuum, they are isolated from the marine environment.
Innovative Cooling System
Our patented cooling system removes heat from within the vacuum enclosure and dissipates it through a glycol/seawater combination. This enables the flywheel to spin at an extremely high rate of speed, providing ultimate performance in the smallest and lightest package possible.
Active Control
Seakeeper's active control works as smart technology, automatically gauging the sea state and reacting instantaneously. This allows for optimal performance at all speeds and sea conditions.

How it works
Inside a vacuum encapsulation, a flywheel spins at speeds of up to 9,750 rpm. When the boat rolls, the gyro tilts fore and aft (precesses), producing a powerful gyroscopic torque to port and starboard that counteracts the boat roll.
