Seakeeper 40

Seakeeper eliminates up to 95% of boat roll, transforming everyone’s experience on the water.

The Seakeeper 40 is designed to eliminate up to 95% of boat roll on boats 85 feet and up (up to 115 tons) and now features field replaceable bearings (FRB). Engineered from the previous Seakeeper 35 model, we've improved performance without sacrificing power, space, or weight. Multiple units can be fitted for larger boats.
