Line
The Hunter 25 is a nice boat. It is also one without an excessive number of lines. My advice would be to replace all your old running rigging (which probably date from 1977, too) with new ones. Lines for your boat are not expensive and you'll have great piece of mind after you do it. Use the old lines for tying up fenders, making baggy-wrinkles, and practicing your splicing technique.FWIT, I helped a friend deliver an old boat a few years ago. We only had to sail about 7 hours, but the winds were gusty. A few hours into the sail, we were close hauled, with the lee rail down. Then the mainsheet (original equipment) parted. We had a few white knuckled moments regaining control of the boat and attaching a makeshift new mainsheet. My friend should have replaced all the lines as soon as he bought the boat....Although you didn't mention it, you should also give some thought to the standing rigging, which is also probably the original and also getting to, or is at, the end of its useful life.
