If it is the boat I remember that was posted a for a long time on Yacht World for $750K then yes, it was in rough shape. Interior was trashed, Salon Window was smashed out, there was extensive fiberglass damage and holes in the hull side around the rub rail engine room area of the boat and just generally looked beat up. It look as some have described as a boat that was on it's side, half sunk and being beat around. I wouldn't buy a sinker, I know how hard and expensive it is to keep all the systems of a straight, clean , non sinker boat working,,,, I couldn't imagine trying to care for one like this.
If the seller thinks he'll bully someone into a quick buy, or raise the price to $500K+ I think he's in for a rude awakening. A Fish Rigged NON Sinker 2001 70C just sold in AL for $640K. So I don't know how he thinks someone that can afford a $500K+ 70 Sinker couldn't bump up their budget $100K to get a boat in better condition. For the unsuspecting buyer this is the case of thinking your saving money buying a less expensive boat and spending Double to keep it running. Then forget about reselling it, unless you practically give it away.
