Designed to eliminate up to 95% of boat roll, the Seakeeper 26 is sized for vessels ~70' - 84’, up to ~75 tons. Unlike traditional external fins, the Seakeeper 26 has no outside appendages, requires only modest electrical power, and can be installed virtually anywhere on board.
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.
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.
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.
