The following is a checklist to get an old boat on the ice. It may or may not be complete. No sign of rust or cracks on fittings especially near holes. Clean rust, replace if cracked. Wire not kinked or frayed.
Blocks turn freely.
Ratchet block works. The forestay is the most stressed rigging on the boat. If in doubt, replace it with hardware from most any rigging shop. Length affects mast rake. If slop is present in through-hull bearings, replace bushings.
