I am not sure this is correct anymore. When I ordered my new rudder, they had the old one for measuerment because I mentioned the you was not satisfied with the angel. I belive there are now two options for the 311

Although I have written many long posts but I don't recall writing one on this particular subject.

I agree that sticking with Jefa seems a lot better than looking for another manufacturer. And if there is no problem with the bearings you should not have to replace them. I had my bottom bearing replaced because the one that came with the boat got the steering completely stuck.

I think it is important to remember that the rudder is not all about size, it is also about profile and thickness.

I had my rudder replaced under warranty in 2008 (when the boat was only 3 years old) for pretty much the same reason Samuel replaced his. The first rudder Hanse sent was the short version which I refused to accept.

I am not entirely happy with my rudder. I think it is thinner than the Jefa version which in theory gives my a faster boat but also one that broaches more easily. A thicker rudder is better for preventing this so it not just the size of the rudder that matters. Also, my rudder has a strange profile that is very sensitive to growth. If I don't brush it clean I will get a weird feel in my tiller. If my boat had a wheel I would probably never have noticed.

I would love to have the Jefa rudder but it is too expensive and I will continue to brush my rudder clean.

And there was me thinking that you were the expert on rudders for the 34 -- i still think you areThumbs Up.

As an aside- Apart from the standard, I seem to recall that Jefa did a racier version with a different profile. It may be worth checking. if this is corect & if it would be to one's advantage to adopt that pattern, if available

I'm impressed by Jefa, nothing is left to chance! They sent me this specification of the 342 rudder, and as far as I have been able to see, it will fit exactly.
So I ordered it, and will receive it around the start of March. I did not order a replacement lower bearing, I will wait until I remove the old rudder and then verify the make and state of it.

Gunnar, how much did you pay for your new rudder?

The new rudder discharged my account by 32000 NOK, including 25% VAT.
Was it worth it? Yes, definitely.
Just getting such a good-looking rudder made me happy, and as it resists broaching much better than the old one it even has a practical purpose, too. ;-)

I agree the Jefa 342/341 (deep profile, wheel steered) rudder is much better than the original supplied with the boat in 2004, presumably from Poland. The Jefa rudder was about 5cm shorter than the original (from memory), and it's performance is much better, particularly regarding broaching. The original rudder suffered from corrosion on the shaft, I was directed by the yard not to sail in open waters after they found the corrosion - luckily I have Sydney Harbour to play in so not an issue.

Jim, I believe you wrote somewhere that the Jefa rudder is also slightly thicker than the original?
