Seakeeper launches Ride to eliminate up to 70% of underway pitch and roll

Seakeeper, launched its new Seakeeper Ride, marking the company’s first product deviation from its line of gyrostabilizers. This Vessel Attitude Control System (VACS) is derived from the Attitude Control Systems (ACS) used  in air and space crafts to control pitch, roll and yaw underway

Seakeeper has always been committed to bringing disruptive technology that represents a wholesale change from what’s currently available,” said Seakeeper President and CEO Andrew Semprevivo. “Seakeeper Ride isn’t an incremental improvement; it transforms what it feels like to be on a running boat. We’re drastically changing the boating experience… again.”


Ride promises to eliminate up to 70% of underway pitch and roll motions, with controllers mounted to the boat’s transom below the waterline. Using proprietary inertial sensing hardware and software, the system takes 1,000 measurements per second to understand the boat’s behaviour in all three axes. It then commands deployment of the custom-designed rotary blades. From this point, Ride makes 100 adjustments per second at speeds of up to 300 mm/s, creating lift that manages vessel motion on the go.


Chris-Craft Boats, Scout Boats and Sportsman Boats are joining Seakeeper Ride as launch partners, making the product standard equipment.

“The Seakeeper Ride system is the next big thing in boating,” said Chris-Craft Boats Vice President of Engineering Ron Berman. “In my years in the industry, I have never experienced a system that improved the ride, handling, and predictability of operating a boat in the way Seakeeper Ride does. All of us at Chris-Craft are looking forward to offering our customers a superior boating experience.”


“We are proud to be a part of the launch of Seakeeper Ride,” said Sportsman Boats President Tommy Hancock. “My team’s first demo really blew us away. I have been in the marine industry since 1984 and can honestly say that Seakeeper Ride is the one of the best innovations I’ve ever seen, giving boaters a far superior experience on the water. This is going to be an industry standard.”


At launch, three products with varying blade sizes will be available. Seakeeper Ride 450 for boats 19-26 feet (MSRP: $4,500), Seakeeper Ride 525 for boats 27-30 feet (MSRP: $7,500), and Seakeeper Ride 600 for boats 31-35 feet (MSRP: $10,500).

Initially, Seakeeper Ride will be available as standard equipment only on select models from Sportsman Boats, Chris-Craft Boats, and Scout Boats as early as September 2022, with plans to increase OEM offerings in the coming year, as well as retail sales for DIY installation.

“Seakeeper has been a wonderful partner for many years,” said Scout Boats President Dave Wallace. “When I was made aware of the new Seakeeper Ride system and then given the opportunity to test it, I soon realized that this would be a game changer in our industry. Seakeeper has brought to boating what the automatic transmission brought to automobiles.”
