42-057 . water intrusion.
significant time and money tracking down the source on the upper deck.
Have removed, caulked the railings, smokestack, mast and all through hull
on upper deck and flybridge.
No luck, still "pouring" out of the overhangs on the fantail overhead.
Any ideas? have only seen previously reponses to caulking the upper deck
to the aft pilot house bulkhead, done and no improvement
Also, what is the core material?

Absolutely great Kevin!
had heard of this flange approach being used to repair fish and commercial
boat rudders (where they apparently often just cut and flip the upper
section of shaft). I figured we might need to do it as well after 20 years
ourselves. So it was great to see your pics. thank you!

Did not want to hijack the rudder 37-40 rudder shaft thread, here is what
we did this year on our 42. When we purchased our boat in 2018, it had sat
idle quite bit and had low hours for a 10 year old boat. I had noticed the
rudder shaft would leak slightly when stopped if it was not centered. When
underway it leaked enough that is was a nuisance. I changed the seal while
the boat was in the water but it started leaking again in about 10-15 hours
of use. So this spring when we pulled the boat for bottom paint, we took
the rudder shoe off to check the retaining bolts after 13 years (their was
no corrosion) and dropped the rudder. We had crevice corrosion on the
rudder shaft and is was concentrated right at the seal area so it needed to
be replaced. We had Sheffield Propeller here in Portland, OR. repair it by
cutting off the bad section, welding a 4-bolt flange to the rudder and make
a new upper shaft with a collar. This fixed our shaft leak and will make it
easier to remove the rudder without disconnecting from the steering in the
future if required. Some pictures of the project attached.
Cheers, Kevin

When bought our Tug, a previous owner had attached a "dinghy rack" on the top deck (other attachments could have been the source as well), and the surveyor found moisture in the cockpit overhang. We had that professionally repaired and also rebed all top deck penetrations that were still necessary (no dinghy rack left). The core was plywood, and for a 3 square foot area was close to "mush". This repair was not inexpensive, but was necessary to maintain integrity.
Good luck,
