Surely to be tue to the forum we should now declare that the rudders will fall off all new Jeanneaus and flame anyone who suggests buying one.
Just to keep things fair of course...

I was tempted, however, whether peeps beleive it or not my motives were honorable. If I had a Jennie I'd want to know about a potential prob.....

So would I, and FWIW I think you are right to highlight it.
Also, I suspect it is probably a isolated incident.
As was the Keel failure on a certain brand, but that never stopped anyone...

Ah but then you are talking Bavs and they're fair game /forums/images/graemlins/smile.gif

Hi Donald. I just want to be part of the gang /forums/images/graemlins/ooo.gif.
Some people seem to have a reflex action .... ooohhh problem with Jen/Ben/any frikkin boat ..... let's knock Bavs. Really don't understand it but hey ho.
A brand new Westerly lost it's keel as the boat lifted on the tide ..... probably 30 years ago.
Relevant? No.
Interesting? Not really.
Why mention it?
Why not.
Has as much relevance to a Jen/Ben rudder loss as the reference to a Bav keel.
ps loved our Tempest /forums/images/graemlins/ooo.gif /forums/images/graemlins/ooo.gif

Chris despite the personal interest in that I own a Jeanneau of a decent age with many thousands of miles sailed and still with the original rudder and shaft I suspect this is not a 'Jeanneau' problem per se but a 'material failiure' problem that could apply to any boat. There is a suggestion of a previous repair after a grounding which may or may not be relevant but the stock was made from a hefty size of solid stainless steel that is common to most boats of that size, probably even on your Rival. Over the years I have seen several boats from a variety of makers with bent S/S rudder shafts but never one that has simply snapped off, snapped off blades yes but shafts no. If the shaft were made from some kind of high tech laminate or alloy or tubular rather than solid it might be different, but I would suspect a faulty piece of shafting in this case that would not have been apparent to the boat builder.

Funnily enough Robin I had you in mind when I posted this, it was the fact that the shaft snapped with no warning that alerted me. As you say it may have been related to an earlier grounding but all the same I'm surprised that a lump of 2" stock can give way in such a catasptophic manner.
Still, we had a mainstay snap not 9 months after all of the standing rigging had been replaced....

Blimey, I must be at ten times the risk, as I have 2 rudders on my Jeanneau, and I regularly grind them into the sea bed when I go aground for the night......
As I have just had a prop shaft replaced, I feel that its time to stock up on new rudder stocks as well. At least a dozen should see me through this season.
Jeanneau for sale.

Looks like someone might have broken a cardinal rule.
Copper and stainless do not go together....IE never never use a copper clamp for your SSB antenna on the back stay as it is inviting problems.
The discolouration iindicates a long time failure with the ultimate failure being the clean material. Is it possible that there was a copper spacer fitted between the hull and rudder collar at some time?
QUote:
The position of the copper alloys in the galvanic series suggests that copper alloys will not suppress crevice corrosion in stainless steels and, in fact, may accelerate crevice attack once it has started. Experience indicates copper alloys provide no useful galvanic protection for stainless steels.
This can also be a problem on rigging bottle screws if they have a copper based lubricant applied. SO avoid having copper in contact with stainless in the presence of sea water /forums/images/graemlins/smile.gif

My gut feeling is that it was a piece of faulty stainless steel that came with an inbuilt defect that would have been impossible to see. As I said I've seen many bent S/S rudder shafts, Westerly Centaurs on drying moorings are high up the list, but a clean snap break with no suggestion of any bending first is something entirely different. Likewise I have seen many examples of crevice corrosion on S/S prop shafts where they sit in dead water in the cutlass bearing, but there is visible evidence of this on the outside surface that is not apparent in the picture of the rudder shaft, although there appears to be some internally in the broken end.
All the boats I have owned had solid S/S rudder shafts, all are still in use and unbroken including one spade rudder on a Trident 24 dating back 30 years still on a drying mooring in Poole! Maybe I'm lucky (and courting disaster now...) but I'm not going to lose too much sleep over it!

Two years ago I was preparing to sail with my pal on his Hanse 371, we were planning to sail non stop from Gosport to Cork, the trip was successful.
However a couple of weeks before departure Phillip Watson lost 'Megawatt' a Hanse 371, in the Irish sea due to rudder failure! Unnerved us a wee bit.
The owner of the 371 did some research. He found out from Hanse and after checking was able to confirm that there is one company that makes rudder stocks for just about every boat on the market. Everything includes Jan's, Bennies, Bav's, HR's, Oyster, the list goes on and on. So the problem is not just a Jeanneau problem, its a lot of peoples problem.
Sorry cant remember the name of the company.

Most boat parts are indeed manufacturered by a few producers for almost all of the boat brands out there. However, good design features are a different thing. My boat has a composite rudder shaft. I was a little concerned at first but then I figured that if the wings of many planes are made the same way so what? - once the quality control is right that is. And so far so good. Perhaps it was one of these shafts as they must be more exposed to manufacturing defects than S/S ones? Interestingly on my boat the shaft is contained within a housing which rises well above the waterline so the boat would not sink if the rudder did fall off.

The problem that caused the failure with Megawatt, was, as far as I can remember, that some 'engineer' retrofitting an autopilot had drilled or cut the SS shaft in the wrong place! As the boat surfed down a wave the rudder shaft snapped, this in turn put pressure on the shaft tube which then tore away from the rest of the hull moulding.
