reply to forestay sag
I have a h430 with an inter-forestay with B&R rigging and I assume you have B&R as well.I run the inter-forestay,when loaded with storm sail,as nearly as taught as the rest of the rigging,however slightly lest tension than the head sail. I have tuned the tension on the standing rigging IAW B&R's guidelines.(one page instructions from Hunter)But, essential, for the 430, you must evenly tighten both sides of the rigging to create a 6% bend in the mast.You can plumb from the top of the mast(not practical if your not on the hard) or eyeball it. I hope this helps. Quick call to customer service to be sure. JC
