I am looking at my first sailboat. I have a fantastic opportunity on a 1977 Seafarer 26. The only problem is I don't know if these are serious signs of an underlying problem or not. The cost of a survey would be more than the boat so that's not happening. The cracks are all on the interior liner mostly in the V-birth storage, but some are in other locations ie Head wall and cabin floor.

Thanks all, I know there are some very knowledgeable sailors here that will help.
