Built to Perform

Behold the first truly practical, and only modern, anti-roll gyro. Seakeeper is designed to virtually eliminate boat roll on vessels 23’ and up. It requires modest electrical power, has no outside appendages, and can be installed virtually anywhere on board.

Meticulously Designed

Every part of the Seakeeper is engineered with extreme precision. The result is an extremely powerful, magical experience.

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.
