My guess is that was never addressed, moulds are expensive to make so I doubt a mould was discarded to “fix” an issue that was deemed not to affect performance.

Noah : The MKI C34 molds burned in late 1993 and I suspect all the design effort was then put into building the new C34 MK II.  The MKII was first shown at 1995 Sail EXPO in Atlantic City.

It would be interesting to hear from MKII owners if Catalina finally got the deck mold emergency tiller aligned with the hull ??

Thanks for playing, Jim! Apparently in 1992 being “off-center” was still the norm!  8)

Guys : It seems as though the spec tolerance was - "if the emergency till arm fits and turns the rudder" all is OK!?!   :o

I would have thought the MKII tolerance would have been much closer to being nearly centered.  The MKI deck to hull match had to be for that emergency tiller!!

Please pardon the slight sideways walk of this question though it is somewhat related. Our cockpit sole gelcoat around the rudder stock cover plate is flexing and has cracked in concentric circles from .5 and 2.5 inches of the plate housing.  Is this an area of concern?

So back in April when I posted my offset rudder post pic, I said I would take a closer look at the rudder before launching.  I did, and think I saw a bit of offset rudder.  I sighted the rudder against the keel. Very difficult to tell.  In the end, there may be a slight misalignment, but it won’t make it to the fix it list or cause any worry.

Bob

Are you referring to a lateral offset, or referring to the plumbness of one vs the other?

Ken,
Plumbness if that’s a word! Sight along each side the rudder and keel.   Looks like bottom of rudder is slightly to port.  Which matches with the rudder post being slightly to starboard on top as viewed in the access port.  But so little, and who’s to say the keel is perfectly set on center?

Clearly now we know why some of our boats list to port!

"Plumbobjectivity"

I maintain {STRONGLY) that CTY at some point started installing keels off plumb to correct the unbalanced weight/design (i..e., port list)  I have much evidence of this on my C30, but the short story is that when I removed my keel to rebed the joint, it was out of plumb (to stbd at the bottom) by an inch or so, VERY precisely measured.  CTY has denied it again and again -- but boy what a coincidence, huh? 
When I reinstalled it of course I hung it plumb--and I introduced a port list.  Thank you, Frank, for warning me of that in our telephone discussions at the time about the keel removal/rebedding.

Rudder post for hull number 1279.  1994 model built October 1993. 
I'm envious of Jim's stainless steel rudder post access cover on Shamrock.  I see that CD doesn't have them anymore.  Does anyone know a source?
