Seakeeper 2

We’ve done it again. We took the groundbreaking
Seakeeper 3 and made it even smaller. 25% lighter
and 20% smaller to be exact. Specially designed for
boats approximately 27-32 feet, the Seakeeper 2
eliminates up to 95% of boat roll. Now even more
people will be able to enjoy their time out on the water.

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.
