One more positive vote
Derrick, I suspect you will get nothing but positive votes on this website, but I will make it one more for the ocean going Hunter 37C.
That said, any H37C that you buy will be over 25 years old and that means lots to renew before you go to sea. Ed Shenck mentions the ports and the rudder - I have changed all these on my 1983. You will also want to upgrade the through hulls if this has not been done (originals were gate valves). Changing the standing rigging is also a requirement in a boat this age. Also check and rebed the chainplates while you are at it. Structurally I don't think you will find any issues. The bulkheads DO creak since they are just slotted into the liner, but the hull seems very strong and well built. The decks are cored (typically with plywood), so go over every inch with a moisture meter - condition will depend on how fastidious the previous owner was about sealing deck hardware. The only thing my surveyor had to add was that all the winches and cleats came without backing plates from the factory, and the bow sections were a bit prone to "oilcanning" (not a serious problem on this boat and easily rectified when you decide to get rid of the "mouse fur" lining in the forward cabin). So, bottom line: this boat was designed for bluewater work and was built to a resonably good standard for the time.
Chances are the H37C you buy will need refitting and upgrading, which may conceivably cost almost as much as the purchase price depending on what you pay and how much work needs doing. I believe that this last statement would apply to any 25 - 30 year-old "stock" production boat.
