I am not very familiar with Schilling rudders... but from experience as a pilot I had to work with a ship with one of those... it's very efficient and we did notice some headway but less than a becker...We could only use its maximum effect (70) at speed less than 4kts... if I recall well

Good luck with your exam...you will have to save that picture... it's too big for this forum, I was very lucky to see a ship approaching Escoumins Pilot station (Canada St-Lawrence river) with the becker rudder sticking out from the water... notice the "hard to port" !

Hi, Becker rudders are "flap rudder" i.e., there is a flap at the end (like an airplane wing)that allows the rudder to give more than 45 degrees of rudder effect, it's really efficient and works very  well. While manoeuvring it can have the effect of a stern thruster but gives a little headway. Schilling rudders are mainly semi-balanced rudders that can turn 70 degrees under 4kts. Very efficient and works very well as well.

Both rudders give very high turn rate at full speed, it has to be handle with care especially on cruise ships. From experience I can tell you: on a twin screw, twin becker rudder,  80000grt,cruise ship of the vision class (royal caribbean International) at 22kts. 2 degrees of rudder angle was enough to give 10/min and the vessel was listing 7degrees (it's a lot on a 2000 pax vessel)

Hope this help you

What a story !, Unfortunately it happens too many times !!!
It reminds me how dangerous the job can be and to be very careful every time I board a ship.

My thought goes to the family of the poor seaman !
