Auxiliary Equipment Operation
STABILIZER- SEAKEEPER
Th e gyro enclosure is secured to two gimbal shaft s that
are supported by a pair of gimbal bearings on each side.
Th
ese shaft s produce an athwart ship gimbal axis for the
gyro to precess to the specifi ed angles.
Each gimbal bearing is supported by saddle beams
which are bonded to the hull stringers. Th
ese beams
transfer the loads that the gyro produces to the hull.
An active hydraulic brake mechanism regulates the ro-
tation about the gimbal shaft .
Th
e gyro features a closed cooling system with heat
exchanger and reservoir, and temperature regulating
valve.
System uses glycol anti-freeze routed through the mo-
tor drive box, hydraulic manifold, and the end caps of
the enclosure to remove heat.
Th
ere is a helm mounted display panel used to start, op-
erate, monitor and shutdown the gyro.
Display provides information in the event of an alarm.
Alarms cause the precession process to stop (Lock) and
the gyro to start coasting down (Stop).

Introduction-
Read the following pages for an introduction to operat-
ing the gyro. For more detailed information refer to the
Seakeeper Operation Manual. Read and understand all
safety warnings before attempting to operate the device.
If installed, the Seakeeper® uses a gyroscope (gyro) to
reduce boat roll motion. Th
e gyro gimbal rotation angle
around a predetermined axis (precession rate) is the
basis of its operation. Th
e amount of torque applied to
the vessel hull to counter a wave induced roll is directly
proportional to the gyro precession rate.
The further the gyro is from a vertical zero degree
position the lower the anti-roll torque. Th
e entire cycle
is actively controlled by an electronic controller and a
hydraulic brake system during each roll. At this point
the gyro supplies the maximum rolling torque and avoids
mechanical contact with hard stops. Th
e mechanism is
limited to a maximum gimbal swing of +/- 60 degrees.
Th
e gyro features a fl ywheel integrated inside a cast
aluminum vacuum-tight enclosure. Th e fl ywheel spins
around the vertical axis and is supported by bearings.
A brushless motor found inside the enclosure turns the
fl ywheel at high velocity.
Th
e gyro enclosure is secured to two gimbal shaft s that
are supported by a pair of gimbal bearings on each side.
Th
ese shaft s produce an athwart ship gimbal axis for the
gyro to precess to the specifi ed angles.
Th eory Of Operation-
Resonant boat roll is the most disorienting contrast
with dry land experience and the least desirable mo-
tion on a boat. Uncomfortable, tiring, and probably the
greatest cause of seasickness, it has been an unavoidable
price to pay for many for the pleasure of being on the
waterways.
Seakeeper’s® unique state-of-the-art motion control
system actively regulates the hydraulic braking system
to ensure the anti-roll torque is maximized for all hull
designs and for the ever-changing operating and sea
conditions.
