Innovative Cooling System

Our patented cooling system allows the flywheel to spin at an extremely high rate of speed, providing ultimate performance in the smallest and lightest package possible.

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. Moreover, because the critical components (flywheel, bearings, and motor) are sealed in a vacuum, they are isolated from the marine environment.

Active Control

Seakeeper’s active control optimizes gyro torque, providing an unsurpassed level of performance. Unlike a passively controlled gyro, which must be turned off in the roughest conditions and/or at higher speeds, the Seakeeper is effective at all speeds and can be used in all sea conditions.

Intuitive Dash Display

Control your Seakeeper with the push of a button on our new user-friendly dash display. Not only is the display simple to use, but it integrates into your existing dash units for optimal performance.
