Buying a 30-40 year old boat - your opinions
I bought a 1985 hunter 40 a year ago. Despite a good survey there have been many items to repair. I think on older boats you should assume pretty much everything needs to be repaired/replaced/upgraded - its just a matter of prioritizing to figure out when. Given your skills, I'd say you are way ahead of the average new-old boat buyer, especially with your electrical background. From the posts I've seen here and elsewhere my impression is that any boat repair can be done yourself, if you have the time, patience and will. Including standing rigging if that's your primary concern. Of course it will probably be necessary to find a yard that can help you pull the mast with a crane if you go with anything even approaching the size of a Sabre 456. Personally I'm finding the learning process of maintenance and repair to be enjoyable and satisfying - a nice bonus on top of the sailing experience, and I don't begrudge the time. Pretty sure this is a common sentiment among owners of older boats.
