The Seakeeper 40 delivers exceptional stability for the largest yachts. Designed for vessels 85 to 110 feet (up to 115 tons), it eliminates up to 95% of boat roll. Building on the Seakeeper 35, this model offers enhanced performance without compromising on power, space, or weight. Multiple Seakeeper 40 units can be installed for even larger yachts for ultimate stabilisation. Its innovative field replaceable bearings (FRB) simplify maintenance and reduce downtime.
