Such difference is a warning that in a certain por-
tion of the hull delamination has occurred, that
is, the glass layers have come unstuck from each
other.
Where delamination is severe, there is no more
structure and the hull is fragile. This sort of dama-
ge is usually repaired by injecting resin or other
materials that serve the same purpose as resin
inside the hull. Alternatively, several layers of the
laminate are removed until the entire delaminated
part is excavated, then new woven rovings im-
pregnated with resin are laid. Such a method is
expensive but effective if delamination is not too
extensive.
2) Osmosis: osmosis is a frightening phenome-
non, but in fact causes no consequence to the hull
structure unless it has been there for decades.
Osmosis only scares our wallet, so we need to
find it out early, or in the initial phase. In case it is
found out, repair work has to be negotiated with
the seller.
