I remember my first boat, a c&c 33 , wonderfull boat, sail fantastic, there is some points to check very carefully in a c&c .
1
keel to hull joint , many c&c are prone to
keel smiling,
2 the status of the
core in hull and
deck , c&c have cored hulls and decks, check for
delamination and moisture content specially close to the keel.
3 bulkheads, because c&c use second liners in the structure and bulkheads are secure in the liner slot, flexing and a hard sailing past made the bulkheads to move out from the slots, chainplates in c&c are secure to bulkheads to, check for
rot wood in this areas.
The bilges in some c&c are flat , standing water in the
bilge , close
inspection to the
mast base and bulkheads in contact with
bilge.
4 Rod
rigging is another feature in c&c , and here the same , close inspection and if the
rigging is 5 years old my sugestion is replace the rod or change to wire.
Here is some points to remember in a c&c and i talk under my experience with a c&c, in any case c&c are terrifics under sail, good windward ability , fast, nice hull lines , in other words wonderfull
boats. I own right now a
csy 44, a big diference , but some times i miss my old c&c.
Good luck .
