Hi. I just bought an Express 37 and I’m trying to figure it out what the block and tackle inside the boom is for and how it should be rigged. You can see one end of with three blocks from underneath the boom right behind the line jams. The end of the line exits the boom about 3/4 of the way to stern and passes through another block and cam cleat. I think it is meant to attach to the backhaul, but mine runs from the back straight to the front of the boom. Anyone familiar with this setup?
