Story continues. Yard sent me pics claiming that the thru hulls were likely to fail since outer sealant seems to be applied on AF. Would be in line with psneelds statement above.
Due to business obligations I wasn't able to have a look on it, only these pics. Personally never saw a disassembled thru hull so I'm unsure in the interpretation of the pics.
Want to achieve a fair cost agreement with the yard. Meaning it has to be fair for both of us - a good job has to be payed accordingly IMO.
Therefore my question: Pics might show old anti fouling or rests of a sealant paste?
What is your opinion?
(The other thru hulls are already on the list for next haul)
