The Seakeeper<\/span> 1 uses gyroscopic principles to dampen cyclic boat roll motions in waves and wakes. 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

Reduction of boat roll is a function of the boat\u2019s 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<\/span>\u2019s active control regulates the hydraulic brake to ensure the Seakeeper<\/span>\u2019s anti-roll torque is maximized irrespective of hull characteristics or operating conditions. <\/p>\n\n\n\n

Operation of the Seakeeper<\/span> 1 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<\/span> 1 requires a connection to a display to support the Seakeeper<\/span> Application; display options include a compatible MFD or Seakeeper<\/span> 5\u201d Touch Display.<\/strong><\/p>\n\n\n

The technical specifications for Seakeeper<\/span> 1, provided in Section 7, list the significant components’ power consumption, total weight, and dimensions. Gyroscopic principles that apply to boat roll control are discussed on Seakeeper<\/span>‘s website at www.seakeeper.com<\/a>. The Seakeeper<\/span> website also contains videos of the Seakeeper<\/span> operation and various boats operating in waves with the Seakeeper<\/span> on and off. It is recommended that the reader play these videos before reading the remainder of this manual.<\/p>\n\n\n\n\n

There is a significant torque about the gimbal axis when the Seakeeper<\/span> is precessing. The Seakeeper<\/span> 1 enclosure prevents personnel or equipment from contacting the Seakeeper<\/span> while in operation. The enclosure should not be stood on or have anything placed on top. The enclosure should always be in place during operation. 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.<\/mark><\/p>\n\n\n\n

Boat operators are advised that the Seakeeper<\/span>\u2019s sole function is to dampen a boat\u2019s cyclic roll motions. The Seakeeper<\/span> is not and is not intended to be, a substitute for adequate hull stability about the pitch, roll, and yaw axes, and the Seakeeper<\/span> is not designed to prevent any instability due to improper boat operation, including, without limitation, any aggressive maneuvers at high speed. During aggressive maneuvers at high speed, the Seakeeper<\/span> outputs a constant pitch moment, which can create a small bow-down or bow-up trim change.<\/p>\n\n\n\n

Improper boat operation, including, without limitation, aggressive maneuvers at high speed, can result in the boat becoming unstable. If you intend to operate the boat in such a manner, you should lock the Seakeeper<\/span> in the vertical position before operating the boat in that manner. Locking the Seakeeper<\/span> in the vertical position is accomplished by slowly turning the boat to starboard in stabilize mode. After turning to starboard for 5 seconds, turn the Stabilize mode off while continuing to turn, and then go to the Service Page on the display and confirm the Gyro Angle is within +\/-10 degrees of 0 degrees.<\/p>\n","protected":false},"excerpt":{"rendered":"
