Hi guys,
Thanks for all your input. With regret I have decided to walk away from the deal.
I went up on Thursday to have a good look round with everything fired up, and found four or five problems, nothing serious, just the likes of the starter motor battery not charging enough, shower mixer leaking etc etc.
I decided I didn't want to take a chance on the hull, so pointed this out along with the faults I found and was offered a possible reduction in price. I declined this as I'd rather the owner got a survey done, and only then I'd proceed if all was favourable. I do not think they have taken me up on the offer as Rosemary is now back up for sale.
It was too much money to take a chance on, although I'm sure it will make a lovely boat for somebody.
Thanks again for all the help,
Mark
