My boat (a '79 Mk-I) was re-rigged ~3 years ago before I purchased the boat. The re-rig included new terminals/turbuckles (swaged); with running backstays, Harken Mk-III Unit 2.5 furler, and insulated backstay, new running rigging on the mast (7 halyards), new stainless lifelines, spartite mast partners. IIRC the bill for the rigging (no yard labor/time included) came to appx. $18,000.
A similar boat (C&C Landfall 38) has a re-rig price breakdown listed here:
