I would look at the
rudder and
steering system very close. Often there is a
packing gland and bushing between the
rudder post and the
fiberglass tube used for the through
hull. Your going to use this rudder a lot and its never an option to have it fail. Also look at all through
hull fittings, on a 1980 vessel they should be re-bedded with a good below waterline compound like 5200. Make sure all metal
parts below the waterline have a ground bond strap or wire connected to a common grounding block to reduce or prevent stray currents that can eat away metal
parts.
Never worry about sailing an older boat. I have spent the past 10 years sailing 1.5 times solo around the world in my 1968
Cal 40. Its ALWAYS better to have a good sailor on a bad boat then a bad sailor on a good boat. No matter, a well found older vessel can take you beyond your dreams. Try not to clutter you boat with too much stuff most of with you will never use to such a point the weight makes you
paint a new higher waterline. Long term boat life is a wonderful lessen in living simple and easy, enjoy your journey as its already started the day you bought this boat, don't be in a hurry, enjoys the new lands and for sure when you meet the peoples learn a few words in the local lingo, drink their wines, eat their cheese and dance to their
music.
I wish you a good voyage.
