If a generalization had to be made about backstay tension (on a fraction rig), what would it be when related to points of sail. Would you want the most tension downwind or upwind? If you want you can rate the points of sail with (tight, tighter, tightest)
Close Hauled-
Beam Reach-
Down Wind-
Again this is a generaliztion and I relaize that there will be circumstances where this doesn’t apply and they could be rather often, but I’m just trying to get an idea here.
