Active Control

Seakeeper gyro stabilizers use smart technology to actively sense the sea state and instantaneously react for optimal performance at all speeds and sea conditions.

Vacuum Sealed

Seakeeper’s vacuum encapsulation not only protects its critical components from the harsh marine environment, but also cuts flywheel weight by two-thirds and halves power draw.

New Dash Display

Seakeeper’s new user-friendly dash display makes stabilization simple. Now, you can integrate your existing dash units, and control your Seakeeper with ease.
