My lf39 has been raced in the Pacific by a previous owner. She is still very
solid. I have sailed her from Washington to Zihuatanejo with no concerns, or
problems. My only current concern is the steering cables in the conduits. Doug

Chuck,Sorry, I should have clarified that I meant balsa cored hull only. I'm
not concerned with decks, and am comfortable fixing small areas there. I don't
believe many boats used balsa cored hulls other than C&C, and certainly not
many meant for bluewater cruising, but I could be wrong. Having seen first hand
how involved a cored hull repair can be (a Landfall 42, and it was above the
waterline, caused by a rafted power boat and some big wake), it does concern
me, but maybe I worry too much...--Shawn wrightshawngwri...@gmail.coms/V

Balsa Core: I'm pretty sure balsa coring was used by almost every
manufacturer from the 70's, 80's and 90's to save weight, add stiffness, and
problems can be detected by a decent survey. C&C used Balsa but so did
Pearson, O'Day, Columbia, Ericson, Swan, Baltic, Beneteau, Jeanneau, Peterson,
Morgan, Hunter, Catalina, Columbia, on and on. If you held a piece of balsa
cored deck and compared it's lightness and stiffness to a solid laminate, you'd
understand why a cored hull is so amazing and highly desirable. I'd say 90% of
the boats in the average boatyard are balsa cored boats, sailboats and
powerboats.
I've done some balsa core replacement and can share photos, but the end
result is faired and painted and the repairs are undetectable, so my boat now
looks better than when I bought her twenty years ago. Plus, all of my deck
penetrations are now overdrilled, filled with thickened epoxy, and redrilled
for the fasteners, so the balsa is sealed from moisture, which wasn't done when
my boat was built. If a deck fastener leaks over time, the water will pass the
balsa core and drip into the boat, alerting the owner to rebed the fitting.
Many balsa cored boats are sailing offshore and around the world.

As we once again consider a boat with cored hull (LF43 or LF38), I am
reminded of why we eventually chose our current 35 four years ago. I couldn't
be sure of the hull integrity without an expensive survey, and at the low price
range we could afford, avoiding a cored hull just removed this concern.
But as I understand it, most C&Cs over 35' have been cored since the late
60s or early 70s depending on the model, so that includes a lot of boats, most
of which are probably still sailing, albeit mainly coastal cruising or racing.
Now as we consider the next boat for our long term offshore boat, things like
potential hull damage from a reef or a collision in a remote part of the world
are a concern.
So I am interested in hearing about experiences with cored C&Cs, problem
which have occurred under both normal use and as a result of damage from
impact, and how effectively they could be repaired.
I guess an additional question is how C&C's balsa coring compares with
modern day foam coring, either with or without vacuum bagging. I assume foam
has some advantages in not absorbing water.
Thanks.
