The Seakeeper 35 is designed to achieve 70 to 90% roll reduction on boats up to 140 tons, vessels >100′. Multiple units can be fitted for larger boats. The Seakeeper 35 requires only modest electrical power, has no outside appendages, and can be installed off centerline, if necessary. Its computerized control and vacuum technology make it the first truly practical, and only modern, anti-roll gyro.

What Seakeeper is right for me?
Frequently Asked Questions
It is a computer controlled gyroscope that eliminates most boat roll, including the fatigue, anxiety and seasickness that goes with it. Because of this game changing effect, PR Nautica have successfuly installed over 30 Seakeeper units worldwide.
Typically, the Seakeeper weighs between 2 and 4% of boat weight, requires half or less the power of air conditioning, and fits in available space down in the after part of the hull. Nothing extends outside the hull and the Seakeeper is a small percentage of the overall volume of the boat.
Seakeepers are sutiable for most boats 30 feet and above. PR Nautica can install the best option on new vessels and as a retro project.
