I couldn't let this note pass as I believe, as an engineer myself,
there is some misunderstanding presented regarding the differences
between engineers, architects, and trades and a confusion of
terminology. There are of course superstars and incompetents in every
professional field. But, generally, the architect (or scientist, take
your pick) is the dreamer, the engineer figures out how to make the
dream a reality (often with a high degree of creativity -- another
misunderstanding about engineers, that they are dull and
uncreative...) , and the trades (builders) implement the engineer's
instructions. A good, experienced engineer will have spent time in
the trades, will be able to build anything she/he designs, and
understands the theory, the stresses, the loads, etc. of whatever is
built. Engineer's do not just draw lines on paper. That's a drafter,
not an engineer. If a thorough evaluation of a structure's condition
is desired, and engineer is the best qualified, by far.

First point: No offense to professional naval architects and
surveyors, but I'd prefer a good boat *builder* look at the boat
rather than an engineer. Engineers are dreamers and they draw lines
on paper. Builders know how to build the engineer's dream and how a
boat and keel should behave and how to fix it and what it will cost.
Yes, I'd rather have Bruckman's opinion than Cuthbertson. The builder
made all those engineer's dreams, all those "lines on paper", into
boats and come to life.
Second point: Maybe the 25 repair costs more than she's worth. Buy a
better and bigger C&C: The market is full of low priced C&C boats.
There are many seaworthy C&Cs on the market for sale. Many 27's,
30's, 32's, 34's, 35's, etc. One of my favorites is the 27 MkV which
has a decent interior space and can be trailored home for winter storage.

1+ to recommendations for a serious evaluation of this issue by
someone who really knows boats—naval engineer, architect, whatever,
unless of course your sailing venue (current and future) is inshore
in reasonable temperature waters and perhaps within easy reach of
rescue and that you require all on board to wear PFDs all the time, etc.
Like most on this list, I am game to tackle most any boat repair,
upgrade, modification, etc. However, and often at significant cost, I
pay a professional to do jobs that are either beyond my wheelhouse or
would require so much prep and research that it would take
forever(allowing for amateur mistakes and redoing certain jobs when
the first attempt goes ‘awry’ for one reason or another).
For any repair or upgrade that might send the boat to the bottom if
it went awry (standing rigging replacement, hull deck joint
refurbishment, centerboard pennant replacement, stuffing box issues,
cutlass bearing replacement, etc.) I use a pro.
Of course with a ‘well found’ boat like C&Cs, there is seldom an
issue with a design flaw at the seaworthy level—in fact I am
confident that my boat design, whatever the details, resulted in a
boat that is ‘smarter’ than her skipper and she will only permit me
to screw things up but so far before her design saves my a— once again!
Most boat issues really aren’t ‘rocket science’ and are amenable to
reasonable DIY fixes. IMHO, this keel wobble issue probably requires
a nautical ‘rocket scientist’ (naval engineer, architect, etc. to
have a look!
