I have just completed a survey on my C&C 99 and the boat is in great condition but the surveyor found a large void with possible water saturation in the Rudder and this was in an area about 12" in diameter. He recommended a manufacturer in So California for a new rudder or contact the class association to see how you go about getting a new ruder and having the old replaced.

I would like to know what your experience has been, the surveyor believed this leaked in via the rudder post , this area in in the top 1/3 of the rudder.


I was about to suggest you contact Tartan Yachts in Fairport, Ohio where the boats were built to inquire if they could supply a new rudder.  However, there are a couple of recent reviews stating that they've gone out of business???,1,,,

I think they have just changed their name and it is TartanLegacy and I believe the contacts are Tim Jackett <>  and  Chris Ranney <> 440-392-2628 and 440-463-2890.  I believe they may still have the plans and moulds.

If that doesn't work I would highly recommend Competition Composites

They are located in Ontario Canada and made a new rudder and carbon rudder stock for my Frers 33 in 2015, excellent craftsmanship and you only pay in Canadian $$$ so you save a lot there.

thank you I am starting the process will update you later

Hi Mark,

 The following is the information from Tim Jackett.  They built the boat so I’d recommend sticking with them.

 We do have the rudder mold and other small part molds for the 99, so we can continue to support the class.

For nearly 15 years I had a similar problem with Kingfisher's rudder, if not worse.  About 1.5 years after purchase, on winter haul out, I would find rusty water dripping out of the rudder.  Continued for 15 years until I got fed up.

Over the years I tried any number of "fixes".  One involved drilling numerous holes in the rudder first to drain the water and later to try to inject foam into the voids.  Some of these fixes seemed to work for a while but never permanently.  It is pretty common in most boats as I have seen in the boatyard, especially sailboats with very long performance oriented rudders.

As I am sure you now realize, the rudder of the 99 is built as 2 polyester shells surrounding a central stainless steel post with tangs.  As the rudder is built up, 2-part foam is laid into the shell before it is sealed around the post.  Unfortunately this inevitably allows for voids.  In addition, under load, the rudder bends and flexes, allowing the shell to separate slightly from the post which in turn allows water to infiltrate and fill the voids.  Given that the internal environment of a rudder is anaerobic, there is a risk of oxidizing the stainless steel post, as evidenced by the rusty water dripping out when the boat is hauled.  That can't be good, right?

If you try to fill those voids, as I did, the first problem is drying the interior of the rudder.  Easier said than done.  I spent many a winter with a vacuum attached to a hole drilled in the tip of the rudder, trying to dry out the core.  Not much success.

In the end, your best bet, IMO, is to replace the rudder and post and while you are at it, the rudder post bushings.  I did this several years ago and have not had an issue since.  However, I did not want to simply repeat the water infiltration issues of the previous rudder so I elected to have a carbon fiber rudder built by GMT Composites in Bristol, RI.  There are several companies who can make a new 99 rudder.  One is in Canada.  However, the import duty and shipping costs for getting the old rudder and post to Canada were excessive so I went with GMT Composites.  GMT can even build a new rudder with a carbon fiber post, if you desire.  They do fantastic work and they are most pleasant people with whom to interact.

I had family in RI so I actually drove my old rudder to Bristol to obviate shipping costs, met with their design team and learned about their manufacturing.  GMT takes the old rudder, laser scans it to produce an exact replica.  Our new rudder was built up in solid carbon fiber (no voids) around a SS post.  It weighs 1/4 the old one (even after it was drained) and is stiff and solid as a rock.  As I recall, turnaround time was about 2 months.

When I pulled the old rudder I also took the time to replace the rudder bushings.  In the original construction (we are hull #6, circa 2002) the bushings were Delrin sleeves precisely machined.  They wear and the rudder begins to wobble.  In making new bushings, I went to NorVa Plastics in Norfolk, VA and they created new precision bushings made from carbon impregnated Delrin.  Much tougher = lower wear. You just need to absolutely clear on the measurements of the bushings and the hole through the hull: OD and ID. The rudder post is as firmly held now as 4 years ago.


Good luck

Great advice, when I renewed the rudder on my Frers 33 I did the carbon post for the same reason.  The stainless steel post had cracks where the rudder stock went into the rudder and you couldn't see them until the rudder was removed.  I had a very good metal guy look at the cracks and he said he wouldn't trust the stainless anymore as it could fall off at any time.

DWW can you send us some pictures of your 99 and some basic contact info and we will add you to the fleet.






I believe I am already registered with your site/chat.  IF I am not, please leet me know.

Yes you are just need info on the boat when you get it all sorted out.



What information are you seeking?  No problems with photos.  Here is one for you.
