I've been cruising the Bahamas and FL Keys on my 1981 Hunter 30, mostly single handed, since 2000. My boat has proven perfectly adequate for my needs. That being said, any older boat should be surveyed before purchase.
I would point out that the problems I have had with my boat; broken prop strut (electrolysis), water pump, alternator, exhaust hose, shifter cable, standing and running rigging, chain plates, bow pulpit, etc., were replaced because of age, not quality of construction. The only unusual repair I had was making an epoxy container to fit around the corroded metal block my mast was stepped on.
I have found my Hunter 30 to be more than suitable for coastal cruising and trips to the Bahamas. I would not hesitate to purchase another Hunter product.
