The Seakeeper<\/span> 35 uses gyroscopic principles to reduce boat roll motions in waves and wakes independent of boat speed. In installations involving multiple Seakeeper<\/span>s, each Seakeeper<\/span> operates independently of one another; therefore this manual only discusses the operation of a single unit.<\/p>\n\n\n\n

A Seakeeper<\/span> 35 consists of a Gyro assembly, a CAN communications cable, and a Display. Figure 1 illustrates the interconnection of these components and their interface with the boat.<\/p>\n\n\n\n

Seakeeper<\/span> 35 technical specifications provided in Section: Specifications and Summary, list the power consumption, total weight, and dimensions of the major components. Gyroscopic principals that apply to boat roll control are discussed on Seakeeper<\/span>\u2019s website at www.seakeeper.com<\/a>. The Seakeeper<\/span> website also contains videos of Seakeeper<\/span> operation and a variety of different boats operating in waves with the Seakeeper<\/span> on and off. It is recommended that the reader play these videos prior to reading the remainder of this manual.<\/p>\n\n\n\n

The gimbal angle and the rate of rotation about the gimbal axis (termed precession rate) play an important role in its operation. These parameters are illustrated in Figure 2. At zero degree gimbal angle, the sphere is vertical; it can precess a maximum of +\/- 70 degrees about this position. The amount of torque that the Seakeeper<\/span> exerts on a boat\u2019s hull to counter the wave induced roll is directly proportional to the precession rate. The farther the Seakeeper<\/span> is from vertical (zero degrees) the lower the anti-roll torque. The vertical arrows in Figure 2 illustrate the direction of the forces that the Seakeeper<\/span> exerts on the boat\u2019s hull to damp roll motion.<\/p>\n\n\n\n

Seakeeper<\/span> precession is actively controlled by an electronic controller and a hydraulic brake throughout each roll cycle so the Seakeeper<\/span> supplies the maximum anti-roll torque and does not make mechanical contact with the hard stops that limit the maximum gimbal angle travel to +\/- 70 degrees.<\/p>\n\n\n\n\n\n

There is a large torque about the gimbal axis when the Seakeeper<\/span> is precessing. Seakeeper<\/span> cover panels are provided to prevent personnel or equipment from contacting the Seakeeper<\/span> while it is in operation. These covers should not be stood on or have anything placed on top. The covers should always be in place during operation. The cover side panels contain safety shields as shown below. Do not operate the Seakeeper<\/span> without these safety shields in place.<\/strong> <\/span><\/p>\n\n\n\n

If it is ever necessary to touch the Seakeeper<\/span> while the flywheel is spinning, the Seakeeper<\/span> must be locked at the display to stop the Seakeeper<\/span> from precessing. Seakeeper<\/span> maintenance should not be attempted unless the Seakeeper<\/span> is locked and the flywheel has stopped spinning.<\/span><\/p>\n\n\n\n
