First 305
Rory:
The Firsdt 305 is a great boat but there are a couple of things to look for. The leatherette covering Beneteau used on the interior has a tendency to come off. This material was backed with a thin foam. Also the windows, which were Lexan, may need to be replaced, look for leaks. Finally re-route ice box drain so you can pump it overboard rater than have it collect in the bilge. Check your keel bolts and backing plates with a magnet to see if they are stainless steel. We loved our first 29 that was the sister boat. She was fast, stable, and could stand up to about anything.
Hope this helps.
