Performance of Schilling design rudders
 

Feedback would be interesting from anyone who has experience of how
effective the Schilling design rudder is on canal boats.

Specifically wide beams 60 ft with 19 or 20 inch props.


Where can you buy or have them made in the UK? At what cost?

Apparently they really come into their own in a 'hard over' rudder
position ie 70 degrees off midships. And are so effective a bow
thruster is almost redundant.


The problem is most wide beam boats will have 50-80HP engine power
available. But with this kind of power during such a manoeuvre, no
human could push or hold a manual tiller over! So power steering
would
seem mandatory and you need a special setup to get 70 degrees.

Curt Schilling designs rudders?

Wow - I didn't know that.

I can't comment about how a Schilling is on a "canal boat". However, on a
ship, a well designed Schilling is (from a boat handling perspective) even
better than a "Becker".
With a bow thruster you can make a ship walk sideways without gaining any
significant headway. My only comment would be to run it by them, for a
specific hull design and steering system.
