Not sure what the arrangement has been with the storage of the boat. No outstanding owed that I know of...but good to check on that.
My cousin had one of the first Viking 28's made and I used to crew with him a bit back in the '70s. Also have a friend with a Viking 33 and I quite like the boat despite its older design characteristics. In fact I like that it doesn't have a cored hull, less chance for major problems.
If the boat looks good I'll talk to the marina to see what I'd be getting into with them.
