Oryx 40 Fly with gyro stabilizer

Gulf Craft has integrated the latest gyro stablizer technology in its Oryx 40 Fly.  This gyro stabilizer reduces, dramatically, the roll of the yacht and helps it to be more stable on water for smooth cruising.

About the Seakeeper 5

The Seakeeper 5 is designed to achieve 70 to 90% roll reduction on boats up to 20 tons, vessels 30-50'. The Seakeeper 5 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.
