independent testing of a passenger vessel fitted with different propulsion systems found that the ABB Dynafin solution managed energy savings of 22% compared to conventional shaftline configurations.
That's compared to propeller shafts I think (and powered by what? Diesel, Gas turbine?).
Voith Schneider systems are generally used on tugs and smaller ferries due to the manueverbility control they provide, it's not clear how energy efficient Voith Schneider systems are to shaftline systems.

Hm, is that a lot?
Oh. That's a lot!

Its efficient at low speeds which is why it can be used on tugs. You want see these on a speed boat.
