The Seakeeper 9 is designed to achieve 70 to 90% roll reduction on boats up to 35 tons. Two units can be fitted for larger boats. The Seakeeper 9 requires only modest electrical power, has no outside appendages, and can be installed off centerline, if necessary. Its computerized control and vacuum technology make it the first truly practical, and only modern, anti-roll gyro.
