I'm looking at a Hunter 25 on the hard in a local marina. It looks like it's had a hard go of it.First, how do I dechipher the serial # HUN 25 0 37/M7/41/G ? I'm assuming that it's a 25, looking at some of the pics on here.Second, I presently own a Catalina 27 "the bus" and a McVay Minuet "the sports car." I'm intrigued by the look of this Hunter as it has a flat top and simple lines. Are these tough boats? It looks like it took quite a smack on the port side hull and has a definite bullseye. Are these foam core? The owner is asking $1,000 for it. It needs some definite TLC and some new keel bolts.Any suggestions as to what I might look for or be aware of?Thanks,Geoff
