Seakeeper Gyroscopic Stabilizers

Eliminate Boat Roll

At Sportsman Boats, we’ve partnered with Seakeeper to deliver maximum comfort in rough waters. Below, you’ll find details on the Seakeeper models available for our boats. We’ve taken this integration to the next level by designing in a dedicated Seakeeper Pod on models where it’s offered. Please note that while this is a designed-in feature, it is not included as a standard option on any model.

DESIGNED-IN FROM THE START

On models equipped with Seakeeper, we've gone through rigorous engineering to create designed-in pods from the start. We can confidently say we've "designed it in" not "adapted it in." This ensures a seamless fit on every model, verified for optimal placement and the best possible Seakeeper performance.

Installation and maintenance are just as smooth thanks to the large Total Access Compartment.

ELIMINATE BOAT ROLL

The technology inside the Seakeeper system is unlike anything else. It uses a spinning flywheel to create gyroscopic forces that reduce side-to-side boat movement by up to 95%.

This keeps your boat steady, helps prevent seasickness and makes for a more comfortable day on the water for you and your family.

SMALL & LIGHTWEIGHT

The Seakeeper makes a big impact in a compact size. Depending on the Sportsman model you choose, we offer the Seakeeper 1, 2, 3 or 4.5.

All four models are compact and powerful, with the Seakeeper 1, 2 and 3 weighing under 550 lbs and the Seakeeper 4.5 weighing 736 lbs. Each has been carefully accounted for in the boat's center of gravity to maintain peak performance and balance.

Once you feel it, you'll never boat without it.

SEAKEEPERS FOR YOUR SPORTSMAN

Seakeeper 1

The Seakeeper 1 brings advanced stabilization to recreational boats as small as 23 feet. With its flush-mount design, it fits perfectly into your Sportsman and delivers maximum comfort in a compact package.

365 lbs.

26' to 28'

$25,875

Seakeeper 2

The Seakeeper 3, but smaller. The Seakeeper 2 is 25% lighter and 20% smaller, built to keep your Sportsman steady on the water. It eliminates up to 95% of boat roll so you can relax and enjoy the ride. Ideal for 30’ to 32’ models, the Seakeeper 2 fits perfectly into the designed-in Seakeeper Pod.

414 lbs.

30' to 32'

$41,080

Seakeeper 3

The biggest "small" Seakeeper to keep your Sportsman steady on the water. Designed to fit seamlessly into your Sportsman as a built-in feature.

550 lbs.

35'

$58,345

Seakeeper 4.5

Packing even more punch, the Seakeeper 4.5 eliminates roll on boats around 40 to 46 feet in a smaller, lighter package. It delivers 50% more stabilizing power than the Seakeeper 3 and runs on AC power for boats equipped with a generator.

736 lbs.

How It Works

Inside the Seakeeper, a vacuum-enclosed sphere, a steel flywheel spins at speeds up to 9,750 rpm. When the boat starts to roll, the Seakeeper tilts, creating powerful gyroscopic torque to port and starboard that counteracts the boat's tilt and roll. Listed below are some of the main features that allow the Seakeeper to operate effectively.

1 - Vacuum Encapsulation

The vacuum enclosure allows the Seakeeper to spin the flywheel three times faster, reduce weight by two-thirds and cut power requirements in half. It also protects the system from the harsh marine environment.

2 - Active Control

The system uses a braking mechanism and smart active control technology to gauge sea conditions and react instantly. You do not need to adjust any settings — the Seakeeper operates fully autonomously.

3 - Cooling System

As heat builds inside the vacuum-enclosed sphere, the Seakeeper uses a proprietary closed-loop cooling system that removes heat through a glycol and seawater combination.

Putting You In Control

The new dash display lets you control your Seakeeper with just the push of a button. Using the dedicated display is simple and easy but it also integrates into your Garmin MFD through the OneHelm app. This will also show important information for maintenance, service, hours and much more.
