Many thanks for your thoughts and the picture so far! I myself would have never considered buying a steel boat with a wooden deck for the obvious reasons - its just that everything else of this yacht is just what I want
The owner claims that this boat has been cruising for 30 years now without any leakages or corrosion issues due to her steel / wood construction. I will have a close look on these arguments next week during the inspection.
By the way, she has been on the market for quite some time now (the latest add just expired) and the current asking price is 65.000 Euros or 88.500 US$. So, beautiful and well equipped as she is, there seems to be a lot of doubt out there in regard to her lightweight construction.
