The Seakeeper 35 is designed to eliminate up to 95% of boat roll on boats up to ~100 tons, vessels ~85′ and larger. Multiple units can be fitted for larger boats. Unlike traditional external fins, the Seakeeper 35 requires only modest electrical power, has no external appendages – meaning no drag or risk of snags – and can be installed virtually anywhere onboard.

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.
