2.0 System Overview

2.1 System Overview Introduction

The Seakeeper 4.5 uses gyroscopic principles to reduce boat roll motions in waves and wakes independent of boat speed. In installations involving multiple Seakeepers, each Seakeeper operates independently of one another; therefore this manual only discusses the operation of a single unit.

Reduction of boat roll is a function of the boat’s displacement, transverse metacentric height(GMT), and hull damping as well as the operating conditions (speed and heading with respect to waves) and sea state. Seakeeper’s active control regulates the hydraulic brake to ensure the Seakeeper’s anti-roll torque is maximized irrespective of hull characteristics or operating conditions.

Operation of the Seakeeper 4.5 requires mechanical, electrical, and plumbing interfaces with the boat. Figure 1 illustrates the interconnection of these components and their interface with the boat. The Seakeeper 4.5 requires a connection to a display to support the Seakeeper Application; display options include a compatible MFD or optional Seakeeper 5” Touch Display.
