Ship stabilising gyroscope is a technology developed in the 1800s and early 1900s and used to stabilise roll motions in ocean going ships. It lost favour in this application in favour to hydrodynamic roll stabiliser fins because of reduced cost and weight. However, more recently (since the 1990s) a growing interest in the device has reemerged for low speed roll stabilisation of vessels. The gyroscope does not rely on the forward speed of the ship to generated a roll stabilising moment and therefore has shown to be attractive to motor yacht owners for use whilst at an anchorage.
