Rig Tension
David,Before altering your forestay you should check if it really is the forestay which is too long. On a still day hang a weight, such as a large wrench, on your main halyard and check if it hangs about 6" aft of the gooseneck. If if does then the mast rake is about right. Try tightening the backstay first as this will have little effect on the rake or, if your boat is B&R rigged (I don't think it is), then tighten the shrouds. The forestay is normally left alone when the mast is down because its length is critical to rake - also it is a pig to adjust. My boat has a collar at the top of the furler spar to stop the sail going too high and this clamped directly onto the wire so I cannot slide the furler up the spar as Jack can do.
