The bottom of the keel missing it’s
paint reminds me of yachts that I
survey that are in berths that are to shallow for them and the bottom bit of the keel spends half its life in mud. Which then stresses the keel
hull join and possibly the
interior floors. The engine main seal could be another can of worms. If he has the part why has he not replaced it yet?
I am not sure I would
purchase this vessel unless you can do all the
repairs yourself.
Cheers
