rudder alignment

[gillows]

Hi all,
Just had the boat out for usual annual clean up (Sealine T46), and noticed the rudders were not parrallel, While looking at other boats I saw 2 other boats with a similar problem, an Azimut and a Fairline, so the questions is, "is it a problem or designed to be like this?"
The yard staff did not know, and just said, leave it if it does not give you any issues, which it does not seem to....
thanks

Rudders can be 'alinged' like this to counteract prop effect.

Thanks, thought it would be something like that.

It's like that on my boat! Wondered what it was.

How/why does that work then? Are they toed in at the leading or trailing edge? With counter-rotating , why does if make a difference?

Hi Paul
Long time no speak!
Reckon with counter rotating it will depend on hull form.
Leading edge I reckon.
Whether toed in or out.
Cos the props are forward of rudders.
No expert Mate.
Just me fag packet type calculations!

Hi

not sure how it works but if it's not right then the steering gets stiffer and stiffer the faster you go.

I had a T46 and the rudders weren't parallel, whereas they seem to be on the Princess, so I guess they adjust them on different boats to give the best performance, either that or you've bought my old T46 !
