Since its roughly her 50th birthday, I figured I'd thoroughly inspect the rudder
post, particularly where it passes through the hull
+ stuffing box, etc and you can't generally see it.
Already after removing some superficial flashing around the top of the rudder
assembly, I have revealed some pitting thats probably a mm or two deep, pock marks like that are all over one section. (see photo
, attached). I'm wondering how to interpret this.
Maybe by describing the whole assembly I can get opinions on if it sounds like overkill with a good deal of safety
envelope, or not...
The rudder post is solid, not hollow, and about 1 5/8" (40mm) diameter.
The boats a 11-12 ton yawl, 41', with probably 6-8 square feet of rudder hung along the aft edge of the cutaway/full keel
An interesting thing with this assembly is that the post is separate from the rudder. The bottom end of the rudder post, which ends up just under the hull
when installed, is splined. There is a mating splined hole in the hefty bronze casting that makes up the frame of the rudder (this casting, plus drift pins, plus wood makes up the rudder). The rudder is also supported by a pintle/gudgeon assembly doodad just below the propeller
aperture as well as a pin that rests in a shoe extending along the foot of the keel
For this reason its sort of easy to remove the whole rudder post from the rudder, so having a new rudder post made is an option.. but an expensive one..
Thanks for any opinions!
EDIT - (for anyone paying particularly close attention to that photo
, its showing up upside down for some reason here)
