This post might be redundant but is to answer a question and not complicate the "40.5 Rudder Stock" post. The question was "Ed, what happened to your rudder?".

During the first nine years of ownership I was always draining the rudder during the off season. And then I would glass sections that were delaminating. Couple that with years of postings here showing rudder failures. So some rudder work seemed to be due.

Then on the journey south from Lake Erie we experienced several groundings(always in the marked channel :) ). One was particularly bad where a fisherman had trouble towing us off. A crewmate remembers that we were finally towed off backward! Still no noticeable problems.

A third factor was a persistent drip around the rudder stuffing box. I had restuffed and adjusted the box at the end of the Erie Canal. So I knew it was the rudder tube and not the stuffing box. It made sense then to have the rudder pulled since I was so close to a real boatyard.

Sure enough when we pulled it the rudder stock was bent. And the first picture shows the source of the drip. The real education was seeing the inside of the rudder, cheap foam and huge voids. The stainless was like new, no sign of corrosion. It was rebuilt with a quality foam, no voids, and a completely new skin. The stock was straightened and the existing frame of the rudder was used.

Cost? State Farm covered it. They said if it was straight when we left Lake Erie then it needed to be fixed. And no rate increase in 2009 and 2010!

Ed:

Thanks for the follow up. I am guessing that your experience would be quite different if you had lived in a salt water environment. I doubt that the frame would have been intact. Out in the west most of the sailors do not have to worry about their rudders freezing.

Another thing that is interesting is that many of the sailors in the midwest and east also have their mast removed each year for storage. This does not happen out west unless there is something going on with the rig or the boat is being transported. I understand that this has been an issue with solid rod riggin on boats. 80% of the failures were originally on boats in the west. This had to do with the lack of inspections and lubrication. The mfg also modified the rigging to accomodate the different environments.

Winters on Lake Erie

Not sure about your adjective "many" Steve. I would choose "some". In my nine years with Ladylove I had one winter with the mast off. And that was because I planned a complete rewiring before the spring launch. As you can see in the pictures, lots of masts and a few on the rack. Mine and a few others for maint. But most from new boats still in the shed.

rudder...

Corecell foam? would seem a good choice...

can you describe the construction? E or S glass?

just curious on the build process...

If they told me Jerry I do not remember. Sorry but I just do not have time to pursue. If you are really interested you might call Sailcraft. Great yard with a lot of huge projects going on. Wish I were there right now.
