Miles Above

Powered by aerospace-inspired tech, Seakeeper Ride is the first Vessel Attitude Control System (VACS), engineered to manage pitch, roll, and yaw with precision.

Eliminate underway motion

Seakeeper Ride reduces pitch and roll by up to 70%.

Perfect Running Angle

Our Trim Command Curve keeps your boat at the ideal running angle for any speed. Optimal trim, every time.

Auto-Leveling

Seakeeper Ride’s automatic list control maintains a level deck despite shifting weight, so you stay balanced without constant adjustments.

Better Turns

In turns, Seakeeper Ride adjusts your boat’s heeling angle for comfort and control.

Seamless Acceleration

Achieve faster acceleration and maintain clear sightlines with Seakeeper Ride’s optimized hole shot.

How It Works

Seakeeper Ride’s transom-mounted controllers sit below the waterline. Using proprietary inertial sensors and software, the system detects boat movement across all three axes, deploying rotary blades to counteract pitch, roll, and yaw. These blades generate lift at the transom, managing motion instantly.

Why It’s Better

Waves are unpredictable, varying in size, frequency, and direction—even within milliseconds. Seakeeper Ride’s rapid-deployment rotary blades make up to 100 adjustments per second to counteract these forces. Nothing compares to the first-ever Vessel Attitude Control System, reducing pitch and roll by up to 70% underway.
