Product Overview

Ride 525 - Full Kit without Keypad

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 the 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.

For those boats that aren’t too big, aren’t too small, but are just right. Seakeeper Ride 525 gives boats 27-30 feet the perfect lifting forces to stop the effects of underway pitch and roll.

Rapid Actuation

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

Full Underway Control

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


Predicts motion and responds instantaneously to eliminate them before they’re felt, with no buttons to push or adjustments to make, providing a boating experience you never imagined.


The 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.

(2) Port and Starboard Controllers

Seakeeper Ride controllers are installed on the transom on either side of the engine(s).

Software Module

The "brain" of the system includes Seakeeper’s proprietary software and motion sensors.

Distribution Module

Provides power and communication between the controllers and the software module.

User Interface

The user interface is compatible with select Garmin, Simrad, and Raymarine MFDs. MFDs are not included in Seakeeper Ride equipment.

Eliminate up to 70% of Pitch and Roll Underway

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