The Seakeeper 3DC is designed to achieve 70 to 90% roll reduction on boats up to 10 tons, vessels 30-40’. The Seakeeper 3DC 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.
