Seakeeper 5 - Gyro Stabiliser
Seakeeper-16-Full-Color

The Seakeeper 16 is designed to achieve 70 to 90% roll reduction on boats up to 70 tons, vessels 65-80′. Two units can be fitted for larger boats. The Seakeeper 16 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

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 weight, 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.

Up to 20 tons, vessels 30-50′: Seakeeper 5
Up to 35 tons, vessels 50-65′: Seakeeper 9
Up to 70 tons, vessels 65-80′ : Seakeeper 16
Up to 100 tons, vessels 80-100′: Seakeeper 26
Greater than 100 tons, vessels >100′: Seakeeper 35

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.
