Seakeeper Ride System

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

When you think about the new Seakeeper Ride, other products on the market may come to mind. First, the Ride product line is not a gyroscopic system like the optional Seakeeper you may have seen on our larger models. It is designed to be installed in the same location as traditional trim tabs. However, its performance far surpasses trim tabs and other self-leveling systems. Traditional self-leveling trim tab systems simply do not have the speed, technology or sensors needed to stabilize the boat. Compared to Seakeeper Ride, those systems are slow and only capable of basic leveling, with no ability to smooth out the ride while underway.

Wave motions can happen consistently or inconsistently, can be big or small and can come from any direction. Often, they occur in just milliseconds. Using Seakeeper Ride’s proprietary software and hardware, rapid-deployment rotary blades make up to 100 adjustments every second to combat these motions and deliver a dramatically smoother ride.

The Seakeeper Ride system is the first-of-its-kind Vessel Attitude Control System. It can eliminate up to 70% of pitch and roll while underway.
Seakeeper Ride controllers are mounted to your Sportsman's transom, below the waterline. Using custom proprietary sensors and software, the system constantly monitors the boat’s behavior across all three axes and computes a counteracting sequence to reduce pitch, roll and yaw. As the blades deploy, they intercept the flow of water off the transom and create lift, instantly correcting the vessel’s motion.

Key Benefits

Pitch & Roll Elimination

Seakeeper Ride eliminates up to 70% of pitch and roll motions while underway, reducing the uncomfortable pounding and slamming often caused by rough conditions. This contributes to greater safety and gives everyone on board more comfort, control and confidence.

Coordinated Turn

Seakeeper Ride automatically adjusts the boat’s heeling angle during turns for better comfort, improved safety and enhanced performance.

Auto Trim

Seakeeper Ride uses a customized Trim Command Curve to automatically adjust the boat to maintain the ideal running angle at any speed.

List/Level Control

Seakeeper Ride continuously counters list caused by onboard movement, wind, uneven loads or prop torque while underway.

Hole Shot Control

Seakeeper Ride improves acceleration to get the boat on plane faster, enhancing fuel efficiency during transition and helping the operator keep a clear view of the horizon for increased safety.

How It Works

Every Sportsman hull is designed to run at a specific angle. Maintaining that running attitude allows the hull to perform at its best, delivering optimal ride quality, performance and fuel efficiency.
On each side of the hull, two controllers do the heavy lifting. Their rotary design is extremely efficient, requiring minimal amp draw. The blades deploy just 1 inch to create the counterforce needed to stabilize the boat.
Seakeeper Ride can go from 0 to 100% deployment in just one-tenth of a second, allowing it to make rapid, precise adjustments. Using proprietary software, sensors and real-time telemetry, it detects vessel motion, calculates a counterforce and instantly responds to smooth out the ride.

Why It’s Better

One of the most exciting features of this product is how intuitive it is. It works completely autonomously, requiring no input at all. Everyone onboard will enjoy a smoother ride from the moment you launch to the second you return to the trailer. Whether you are a weekend warrior heading to the sandbar or a hardcore offshore fisherman, Seakeeper Ride is 100% effective in all conditions.
Another advantage is its ability to keep the boat level as weight shifts around. With traditional trim tabs, if a person moves from one side of the boat to the other, manual adjustment is needed. The Seakeeper Ride system eliminates this by auto-leveling on the fly. Thanks to its speed, it not only levels but actively stabilizes for a much smoother ride.
While being autonomous is a major advantage, some sea conditions may require slight adjustments. For that, the Seakeeper Ride app, built into the Garmin screen, allows you to make changes. In the Ride system, these are known as "bias" adjustments, letting you fine-tune the running attitude or intentionally create a list to match sea conditions.

The Seakeeper Ride system still lets you stay in control when needed. In certain sea conditions, you may want to adjust the boat's running angle. Using the Seakeeper Ride app built into the Garmin, you can add a bias to tweak the running attitude or create a list to suit conditions.
For example, if you need a slight angle to one side, simply open the OneHelm App and press the port or starboard bias button. The Seakeeper Ride will continue to stabilize the boat while holding that bias. When no longer needed, you can easily reset it back to zero.

Proper engine trim is crucial for achieving quick time-to-plane performance and Seakeeper Ride helps here too. The system reads the Trim Command Curve profile programmed into each boat. These profiles are tuned to deliver great all-around performance across a wide range of conditions. For advanced users who want even more control, the app offers an advanced settings section to fine-tune the system to match their boating style.
