Hi, we recently took part in our first regatta in 18 months, only 9 boats but was good to get out racing again. because of Covid, the regatta was held in a different weather seasonthan normal. 
We had between 0 and 35 knots true wind which made choice of downwind sail interesting!. We got caught out a couple of times under spinnaker which meant that a lot of helm input was put in. When we got back we noticed that the dead ahead lashing on the favoured starboard wheel was 35-40 degrees out in comparison to the port wheel when the rudder is midships. I have checked out the steering cables and the tension appears correct, a little bit of vertical play but certainly not enough for the chain to have jumped a cog on the wheel sprocket.
I took the wheel and the bearing support off and everything looked fine.
The only thing I can think of is that the wheel turned around the centre nylon(?) spacer as there doesn't seem to be anything connecting the inner stainless steel ring that bolts to the steering spline and the outer ring that takes the spokes of the actual wheel as per the photo below.
I have raised this with Jefa and am awaiting their response but has anyone else come across this?
All the best and stay safe!
Paul

hello Paul
Did you checkt the shaft keyway is in place on the conical shaft of the wheel?

you take off the bolt and the wheel so you can see the keyway is still in place on the shaft

Hi, yes I checked that, the keyway is there and firmly locks the wheel in position. When I took it apart I couldn't see any mechanical reason for the wheel to slip round.
All the best

I forgot to add that there is no play between the wheels and the rudder, all works as normal. It is just that the starboard wheel has moved round 35-40 degrees!

Itís possible that the wheel has slipped on the center hub. It looks like there is a bushing material on the hub that may have let loose a bit.

Is it just the case that the dead ahead lashing has moved?

Hi, Ian that would be the easy answer! but no it definitely hasn't moved as it has been lashed onto a  chamois covered wheel for over 7 years and I am sure the fabric under it is considerably lighter and probably cleaner!
But thanks for the suggestion
All the best

Also the amount of rotation we have would mean that the lashing would have had to jump over one of the wheel spokes!
