Interesting video.

I wonder how it affects bow-to-stern movement? It is a gyro - seems
to me that if it has that much of an effect on side-to-side roll, it
would have the same effect on bow-to-stern movement..
The gyro vacuum enclosure appears to be mechanically restricted to fore
and aft gimble movement, so I suspect it stabilizes on one axis only.

How the fore and aft movement translates to stabilizing beam to beam I
think has something to do with the principles of gyroscopic progression,
similar to helecopter controls of blade pitch.

But, I might be wrong.

I've been studying the drawing of the system and thinking about it. I think
I know how it works.
Pretty clever. When the boat starts to rock, the spinning gyro exerts a
force opposite to the boat's rocking direction. That force is coupled to
the beam located in the boat (probably a stringer) that either lifts or
pushes on it to counteract the direction of the "rock".

And then the boat cracks open and sinks...
