The back stay has allowed us to tighten up the forestay in heavy wind to prevent a sag to leeward. The back was partially make from the 4-1 rope boom vang that was standard equipment on the boat.. The rope vang was replaced with a hard vang Garhauer Marine. The were additional parts needed and were purchased from the local marine store. We now have a 8-1 purchase on the back stay.
