Location
The Gyro Stabilizer should be located in a soundproofed machinery space that is aft of amidships. The space must contain a mounting position that has sufficient structural coupling to transmit the gyro's righting torque safely and reliably to the hull structure.
The Gyro Stabilizer does not have to be located on the centerline of the boat. Its effectiveness is independent of its location relative to the boat's centerline.
Gyro noise has been measured under steady state conditions (no wave load) in Seakeeper's lab and in our 43 ft Viking test boat. The steady state noise is typically in the range of 70-80 dB unweighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the gyro be installed in a machinery space that is treated with soundproofing. If the gyro stabilizer is located outside a machinery space, soundproofing is required to eliminate low frequency (approximately 160 Hz) noise from entering living spaces.
