The Hunter 34 has had several problems. The compression post tends to rot out out as the water leaks in where mast wire penetrate the deck. A lot of owners have replaced with a stainless post.Look for deck compression which is common. The ladder grid in the bilge creates areas where water can not escape. A couple of 34s I know of have had to have ladder stingers cut out and replaced because of rot. The forward sections of the hull are large and flex quite a bit in a seaway.
The H34 has an iron keel and is a little under ballasted. First reef about 15 knots apparent wind.
Bottom line, a lot of boat for the money. OK if the boat has underlying construction deficiencies fixed and that you don't mind maintenance problems of an iron keel.
