How Seakeeper works

Seakeeper is designed to eliminate boat roll on vessels 30′ and up. It requires modest electrical power, has no outside appendages, and can be installed virtually anywhere if necessary. Its computerized control and vacuum technology make it the first truly practical, and only modern, anti-roll gyro.

Seakeeper is a computer controlled gyroscope that eliminates most boat roll, including the fatigue, anxiety, and seasickness that go with it. Typically, the Seakeeper weighs between 2% – 4% of boat weight, half or less the power of air conditioning, and fits in available space in the back half of the boat. Seakeeper’s models can accommodate boats over 30′. They can be installed virtually anywhere on board. This flexibility means that approximately 25% of the units are installed aftermarket.

Inside a vacuum encapsulation, a flywheel spins at speeds of up to 9,700 rpm. When the boat rolls, the gyro tilts fore and aft (precesses), producing a powerful gyroscopic torque to port and starboard that counteracts the boat roll.
