** STABILIZATION FOR SMALL BOATS **
They say great things come in small packages and Seakeeper set out to prove it. The Seakeeper 3 is their biggest smallest thing yet, specially designed to eliminate roll on ~36’ - 39’ boats. Refits have never been easier than with the Seakeeper 3’s leaning post-installation option!
IDEAL FOR BOATS: ~36' - 39'
ELIMINATE BOAT ROLL
Eliminate up to 95% of boat roll and the danger, fatigue, anxiety, and seasickness that go with it.
SMALL & LIGHTWEIGHT
Seakeeper weighs only a small fraction of the boat's displacement.
FLEXIBLE & EFFICIENT
Simple installation, quiet operation, and no generator necessary. 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.
UNDER THE HOOD
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.
