Hi Holmek,
We are taking the thread off track, but ...
A short time ago I made a similar inquiry about cored hulls. To summarize: Coring makes the
hull light and strong if done correclty. A good
surveyor will be able to detect
delamination and/or rotting of the
core below the
water line. A thru-hull on a cored hull is a potential point of
water ingress on a cored hull if not done right. When the hull was laid it up there should have been solid glass at the points where a thru-hull was to be installed. If thru-hulls were installed after the hull was built then at the point of the hole the
core should have been taken back far enough to put in
epoxy and seal the core material away from any possible moisture. My own sense of things is that the older the
boat, the more likely it is that there has been moisture ingress unless you know explicitly the
history of the
boat and its owners.
As for rod riggning, there are pros and cons which I will let others address. But, once again, be aware that everything wears out over time. That is why a good
surveyor is invaluable.
