This J/99 page brings the main rigging-planning information together so an owner can move from an early estimate to a checked specification. Winch guidance is kept as an optional deck-equipment item, which helps distinguish a core re-rig from upgrades that may be desirable but are not essential to the stay set. 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. To turn the model guide into a manufacturing specification, measure the existing stays and confirm terminal forms, pin sizes, turnbuckle threads and the exact way the forestay connects to the furler.
