Hi Randall,
Regarding rigging,
I have 1983 Hunter 34 and replaced all the standing rigging.
I used Seacost South in Florida. They were the best price and duplicated everything exactly. My rigging was all original and well maintained as I am original owner. I was under the false idea that if it looks good don't fix what is not broken. I held on to this thought for the past ten years untill I saw a fellow sailor have his mast fail. Now they have not only the standing rigging to replace but now have to add to the bill a mast, running rigging, electronics, and damage to boat. All not covered 100% covered by insurance due to age of rigging and no proper documentation of its replacement because it was never done.
His total bill is now over 7k. Stories of other people's rigging failures. Seeing and hearing horror stories put that monkey on my back and makes you wonder is today going to be the day the rigging fails?
The moral of the this is Don't wait until it's to late.
Not worth someone getting hurt.
When Seacost South did mine they said it looked ok however you never can see what it going on inside the swaged fittings.
After I replaced it I now have peace of mind and can't put price tag on that.
Regarding opening ports
See my post refurbishing hatches cheep.
You can usually get replacement screens and gaskets fairly cheap. Toothpaste and a paper towel works absolutely amazing to remove decades of haze on the lenses with almost no effort.
Hope this is helpful
