The other (Linwood) Skip has it right. See below.
For those thinking of sleeving, I looked very hard at that; it basically wouldn't work
for our application due to size.
For those saying "turn it, weld on new, turn again" it's pretty difficult to find a shop which has a 3' on center swing on a lathe. There are machines which can attach to a shaft and turn/reduce it in place, but it's beyond stupid in cost.
Foss Foam doesn't have the molds for this, though they did at one point, for those thinking of remaking as a solution, whether or not with the same shaft (I have a good friend, not our boat type, who sent off their shaft for another rudder, all the way from Grenada
and back, to the tune of 4 boat units - and only that cheap due to their providing the shaft).
Our solution is covered in our pictorial here: Pictures: Flying Pig Refit 2011-2012/Rudder
Those, such as the OP, or merely gruesomely fascinated, may care to peruse other places in our gallery; you can get there by going to the top of the page and backing up the tree.
There's pretty much no place on the boat - sometimes even those hidden - that I've not either had my hands in, a tool in, a light and camera
, sometimes with mirror, so I have a concept
of where the bodies are buried, so to speak.
To the OP (or any other Morgan

if you'd like to pick my brain or just chat.
