Very interesting.

I'm not sure I believe this part:

In the high-speed scenario, the leg and pod will shear off flush with the
hull. The lower bearing carrier has been engineered specially to break at a
point below the O-ring seal between the fixed and steerable parts of the
drive. As the leg bends backwards, the vertical drive shaft simply pulls out
of its spline. The inside of the transmission is now open to the ocean but
no water can escape into the boat and the vital mounting joint between
transmission and hull will remain not only intact but undamaged thanks to
the energy absorption of the big twin O-rings.
