Seakeeper Ride 525 for Boats 27 - 30 ft

A first-of-its-kind Vessel Attitude Control System (VACS)

Seakeeper Ride 450
Experience exceptional pitch and roll stability on smaller vessels measuring 19 to 26 feet in length with the Seakeeper Ride 450. You can achieve significant results without requiring a large boat.

Seakeeper Ride 525
Boats that fall within the 27-30 feet range can benefit from the Seakeeper Ride 525, which offers precisely calibrated lifting forces. This innovative solution effectively mitigates the negative effects of pitch and roll during navigation, ensuring a comfortable and stable experience. The Seakeeper Ride 525 strikes the perfect balance for boats that are neither too big nor too small.

Seakeeper Ride 600
Don't let pitch and roll affect your enjoyment on the water anymore. The Seakeeper Ride 600 is capable of providing the necessary stability for your 31-35-foot vessel.

Seakeeper Ride 750 and Seakeeper Ride 750 Quad
What's the difference?
• Seakeeper Ride 750: This system has two controllers and will fit most transoms.
• Seakeeper Ride 750 Quad: This system consists of four smaller controllers and is suitable for unique transoms that may have hull design elements that restrict available space.
• Both systems were designed with aluminum components for added strength.

Most 37-42ft boats will be able to fit the two controllers in the Seakeeper Ride 750 system. Seakeeper recommend the Ride 750 system if the transom geometry allows for it (less cost for you, less installation work). If there are obstructions or elements of the hull design that restrict the available space for the use of two larger controllers, the Seakeeper Ride 750 Quad system is an alternative that may make a Seakeeper Ride installation possible.

How Seakeeper Ride controllers work
Seakeeper Ride controllers are mounted to your boat’s transom, below the waterline. Using custom, proprietary inertial sensing hardware and software, the system understands how the boat is behaving in all three axes and commands deployment of the rotary blades to counteract pitch, roll, and yaw. As the blades are deployed, they create lift at the transom, managing the vessel’s motion instantaneously.

Why it’s better
Wave motions can happen consistently or inconsistently, they can be big or small, and can come from any direction. Often, these motions occur in just milliseconds. Thanks to expert control software and hardware, Seakeeper Ride’s proprietary, rapid-deployment rotary blades make 100 adjustments every second to combat wave motions.
Nothing compares to the first-of-its-kind Vessel Attitude Control System, Seakeeper Ride, which can eliminate up to 70% pitch and roll underway.

Eliminate up to 70% pitch and roll underway
Nothing compares to the first-of-its-kind Vessel Attitude Control System, Seakeeper Ride, which can eliminate up to 70% pitch and roll underway. Our proprietary, rapid-deployment rotary blades make 100 adjustments every second to combat wave motions, providing unmatched performance.

Additional Features

Rapid Actuation
Rotary blades deploy at a rate of up to 300 mm per second, making 100 adjustments every second; enabled by power-dense rotary design that requires just 7-10 Amps for operation.

Full Underway Control
Controls all motions (pitch, roll, yaw) thanks to deployment speed and proprietary control software and hardware.

Intuitive
Predicts motion and responds instantaneously to eliminate them before they’re felt with no buttons to push nor adjustments to make, providing a boating experience you never imagined.

Reliable
Drivetrain is completely sealed in a dry and greased environment with no mechanical exposure to saltwater.

Simple Installation
Easily installed on most transoms, both in new and aftermarket boats.
