... no longer wanted their boat! Like any story this too raises more questions the more I read. We're they insured? How long has they been out there floundering? What is their background? What were the conditions encountered on the trip etc.
Somebody on this forum made a comment about not being too judgemental without knowing what the reality of the situation was... I understand their point. There have been a couple of times in the Gulf Stream where I would gladly have sold the boat for a dollar and basically the boat was seaworthy if not 100%.
As far as the 66 days at sea...I also read the comments in the Cruisers forum. Those made by the previous owner suggest you may be correct, your concerns may well be justified. I going to keep an eye on this one too.
