Angular Momentum V’s Anti-Roll Torque

What is the most accurate way to determine the performance of a gyroscopic stabiliser?

To understand the difference between ‘angular momentum’ and ‘anti-roll torque’ and what is the more accurate way to determine the performance of a gyroscopic stabiliser, we have an analogy to present.

Angular momentum is like the horsepower of the engine in your car. You can have a 500hp engine in your car but when you test the horsepower at the wheels or where the vehicle delivers the horsepower to the road, you realise you are only delivering 400hp.

It is the horsepower you deliver to the road that actually matters because this is what delivers the performance of the vehicle.

The same thing happens with a gyroscopic stabiliser. You can have a massive big spinning mass that generates loads of angular momentum, but the precession angle and the way the system and all the components are designed to deliver that energy to the hull are actually what determines the anti-roll torque. It is then the anti-roll torque, that is effectively delivered to the structure of the vessel, that determines the anti-roll performance of the gyroscopic stabiliser and the stability of the boat.
