They say great things come in small packages and we
set out to prove it. The Seakeeper 3 is our biggest
smallest thing yet, specially designed to eliminate roll
on ~35-41 foot boats. Refits have never been easier than
with the Seakeeper 3’s leaning post installation option!
No one knows more about how you boat than you! Enter your boat information and we will guide you through the options so you can decide which Seakeeper is right for you.
| Weight | 550 lbs (249 kg) |

Our patented cooling system allows the flywheel to spin at an extremely high rate of speed, providing ultimate performance in the smallest and lightest package possible.
Seakeeper’s vacuum encapsulation enables the flywheel to spin roughly three times faster, cuts flywheel weight by two-thirds and halves power requirements. Moreover, because the critical components (flywheel, bearings, and motor) are sealed in a vacuum, they are isolated from the marine environment.
Seakeeper’s active control optimizes gyro torque, providing an unsurpassed level of performance. Unlike a passively controlled gyro, which must be turned off in the roughest conditions and/or at higher speeds, the Seakeeper is effective at all speeds and can be used in all sea conditions.
Control your Seakeeper with the push of a button on our new user-friendly dash display. Not only is the display simple to use, but it integrates into your existing dash units for optimal performance.
