Here's what we use around here. We call it a Portuguese turnbuckle. It makes mast rake and rig tensioning easy and can be done solo. Start by tying about 3 feet of 5/32 line to your forestay. When you've looped it to about 3 to 1 onto your bridles/furler you can haul downward and tighten the rig WAY tight. If you want to rake further just ease this turnbuckle, drop the side stay pins down a hole and retension the turnbuckle. Tack your jib to the furler shackle and the whole turnbuckle hides inside the jib luff.
