jeanneau rudder

[ianmoondance]

Firstly i would just like to say hello as its my first post here.

Ive spent quite a while searching the net as i have a problem with the rudder on my Jeanneau Fantasia27. The rudder is/was transom hung on two pintles.

I say was because the boat is on a swing mooring in N. Wales and in the bad weather last weekend the rudder, despite being lashed in the central position, seems to have banged hard against the stub of the boarding ladder and shattered just below the top pintle. The bottom section of rudder then sheared the bottom bracket pin and was lost.

I now need to replace the bottom set of brackets and rudder so a few questions please.

Does anyone know where these could be sourced? I am prepared to travel to collect.

Failing that could anyone offer a bit of advice, the existing section of rudder i have left is constructed from 50mm ply, is it likely that the rest of the rudder would have been made from the same material?

So far i have only been able to find 25mm marine ply, does anyone know a source of 50mm or can suggest the best contruction means of bonding two x 25mm sheets?

Finally if i have to constuct the rudder ( a job i dont mind doing) does anyone have the dimensions of a rudder to fit a jeanneau fantasia or have a boat somewhere in N. Wales or the N. West which they would allow me to have a look at and measure up?

I am aware it a big ask for a first post so i would like to say thanks in advance for any help that could be offered.

Hi Ian,

I can't help you with your specific request but as you haven't had a response (unusually) on here, can I suggest you try the Jeanneau owners forum, you'll have to Google for it as I havent worked out how to include a web address via my iPad. Good luck.

Thanks for that.

I posted on the jeanneau website at the same time as here and have had some excellent help so far. So your help is also spot on and much appreciated.

Can't help with the shape, but to get 50mm ply you will have to laminate either 2*25 or 4*12.5. The lower part will almost certainly be shaped and tapered. It may have been made with one central solid lamination and cheeks added to the upper part. The break might have occurred just below the cheeks. You really need to find an original before you decide how you are going to make it.

Fantasia 27

I have a small Jeanneau so I've bookmarked relevant resources.
To look at the part nos. but not necessarily to buy you can look at :
http://www.jeanneauparts.com/en/index.php?cp_sid=1388412be5bbe&cp_tpl=main
The site is run by MAXMARINE.You don't have to log in in order to use menu :
i.e.Sailboats / Fantasia 27.
From the prices,which may not please you,and my experience I would say that this is definitely for a high tech. composite (grp perhaps with carbon fibre/kevlar) rudder with an efficient foil section.(like ours)
i.e.not plywood,which someone has used to replace your rudder.
You can order parts in UK via Clarke and Carter although they don't offer the same data 'service' so the German data may be useful for identification.I would expect the cost of any bits to be the same in pounds as in euros on the list,perhaps including carriage.
If this helps ............

Thanks very much for the replies.

Yes you are right Bluerm, those prices are a bit prohibitive but it might help with the brackets so thanks for posting the link.

It looks as though the rudder is going to have to be constructed so the next priority is to get the dimensions. Ive been searching through the net for brokers in the hope of finding one out of the water but if any one does see one id be most grateful if you would give me a shout.

Not brilliant but any chance of scaling it from this?

I've built dinghy rudders before from a western red cedar core (you could use HD foam) sheathed in UD and weave carbon. You can download NACA foil profiles from the net, a 0010 profile works well. Start with a squared off blank, construct an mdf jig that is a box that the blank slides exactly through, and you basically make guides in the middle of the box so as you slide the blank through, you can rout out slots to the desired profile across the rudder chord, rather than along it.

If your router is 10mm wide, rout the slot, push the blank through so you have a 10mm gap, then do another slot, until it's done. You end up with a "comb" effect where the high bits keep the blank snug in the jig for accurate routing,and the low bits are the desired profile. Flip it over, do the other side, then power plane/belt sand the high bits down to the low bits and you have a very accurate blank ready for lamination. You could also make 2 half blanks, and rout a bit of meat out of the middle to save weight, or for that matter laminate a bit of 316 s/s down the middle to make it bomb proof...
