Crafted for ~60’ - 69’ boats, up to ~50 tons, the Seakeeper 16 is designed to eliminate up to 95% of boat roll. The Seakeeper 16 is completely internal, requires only modest electrical power, and can be installed virtually anywhere onboard.


IDEAL FOR BOATS:  ~60' - 69'



Eliminate up to 95% of boat roll and the danger, fatigue, anxiety, and seasickness that go with it.



Seakeeper weighs only a small fraction of the boat's displacement.



Unlike traditional fins, Seakeeper is completely internal and can be installed virtually anywhere. Regardless of where Seakeeper is installed, either on or off centerline, performance will remain the same. That’s because it’s attached to the structure of the vessel and will distribute the same forces throughout the hull.



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 for life in a vacuum, they are forever isolated from the marine environment.


Active Control

Seakepeeper’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.



EXTENDED WARRANTY options to suit your needs!
