Seakeeper 9 Retrofit
A Seakeeper retrofit on the Princess 56
The Seakeeper 9 is designed to achieve 70 to 90% roll reduction on boats up to 35 tons, vessels 50-65′. Two units can be fitted for larger boats. The Seakeeper 9 requires only modest electrical power, has no outside appendages, and can be installed off centerline, if necessary. Its computerised control and vacuum technology make it the first truly practical, and only modern, anti-roll gyro.
This Princess 56 was given a full Sea Trial before and after the Seakeeper install so the performance data could be compared. Weighing only 350kg the Seakeeper 9 had almost no negative effect on the performance of the vessel, the same RPM and top speed were reached and a negligible difference in fuel consumption was recorded. This data is available on request.
Using specialist sensors and software we were able to determine a 90% reduction in roll during our Sea Trial.
