There is a way
Hello,When Bob Perry's clients ask him what pressure their hydraulic backstay adjusters should read, he tells them, "Put a piece of duct tape over that damned gauge! Look up the luff of the jib, and tighten until it's right!"Sound advice, and pertinent here. You can't measure the tension in that stay if it's hidden by a foil, but you can see the amount of luff sag, and adjust tune accordingly. The maximum amount of sag will be on — not off — the wind. On a B&R you won't be able to get as tight a stay as on a masthead rig, but remember, the jib is a minor player here. Concentrate on distribution of the total load among all the shrouds and diamonds. Get a fair mast curve, the right rake, and then eyeball that jibstay under way to see how it looks. There will come a point when no amount of tightening will improve the shape; back up a turn or so and nail it, assuming you haven't exceeded 15% or so on the V1's, or anywhere else.Fair leads,Brion Toss
