Hello,I am looking to purchase a used sailboat and have been looking at a couple. The '74-'83 30' Hunter seems a good choice for what I will need. Two adults and two small kids going for weekends to the keys from Miami.I have not owned a large boat for a while and have a couple of questions.First, I have seen some very reasonaby priced boats (low teens) that seemed in good condition but cosmetically a bit of a mess. Especially the interior seems very run down on these older vessels. How big of a project is it to get an interior from rough to nice and most important impeceably clean with a pleasent smell?Besides making sure the engine has some life left in it, what culd be the biggest problem with a 25 year old boat? I am planning on a thourough sea trial and a survey. But what should I look for and which ones should I turn down? What's the best or worst case getting a used fairly old sailboat? Reading some of the reviews many owners seem to have issues with the "i-beam". What is involved for repair and how to look for problems?Thanks a lot,regards,Sab.
