For a J/120, this page provides a practical starting point for planning replacement standing rigging and related equipment work. The page separates standing rigging from running rigging and deck equipment, making it easier to decide which items belong in the immediate refit and which can remain optional. Model data is most valuable when it is compared with the boat in front of you, because small hardware changes can affect the finished length and termination required for a replacement stay. A reliable production schedule should record stay count, wire or rod size, finished dimensions, mast terminals, chainplate pins, turnbuckle threads and the forestay connection through the fitted furler.
