How it Works
Inside a vacuum encapsulation, a flywheel spins at speeds of up to 9,750 rpm. When the boat rolls, the gyro tilts fore and aft (precesses), producing a powerful gyroscopic torque to port and starboard that counteracts the boat roll.
Frequently Asked Questions
What is a Seakeeper and what does it do?
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.
How much does the Seakeeper weigh, and what are the power and space requirements?
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.
Is there a Seakeeper suitable for my 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.
I have an existing boat, can a Seakeeper be installed after build?
Yes, we can fit Seakeepers to both new vessels and aftermarket. The time of a retrofit installtion will vary depending on the Seakeeper and the model of the vessel. Typical installation time is 1-3 weeks. Get in touch for a custom quotation.
