Thanks for the inputs. I am not against the survey or the surveyor. They did their job.
He found moisture above decks, no delamination and said that is normal on older boats. I am complaining and pissed off at the owner for not admitting the very obvious and serious defect in the hull. It is very visible to the naked eye when hauled out and they admitted they knew about it.
They are just plain liers and now they have to repair it anyway. The extent of the damage is to chancy for me. There were also voids in the rudder.
Something was definately wrong with this hull.
