Seakeeper 35

Seakeeper 35

Regular price $216,300.00 Sale

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 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.

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.
