Adjusting the tension on the running backstay has two effects: First, the forestay is tensioned (controls sag in headsail) and Second, mast bend is increased (the mast becomes more bent). The overall effect of tensioning the running backstay is a shallower mainsail (less camber) combined with a reduction in headsail sag. 302:
boats invariably have running backstays with no permanent backstay. In both of these cases the mainsail extends aft of a line from masthead to stern, and so a permanent backstay would interfere with the operation of the sail. As a direct consequence of its attachment point (below the top of the mast)

A running backstay always attaches to the mast at a point below the top of the mast and is generally used in conjunction with a permanent backstay. Running backstays are found on both masthead rigs and fractional rigs. There are some rigs for which running backstays may be used without a permanent

A permanent backstay is attached to the top of the mast. Running backstays appear in pairs attached about two-thirds of the way up the mast (sometimes at multiple locations along the length of the mast). In general, most modern sailboats have a permanent backstay and some have a permanent backstay
281:, tensioning the permanent backstay has two effects: First, the forestay is tensioned (controls sag in headsail) and second, the mast bend is increased, particularly in the upper one-half to one-third of the mast. Increased mast bend tends to reduce the draft ( 314:
If the running backstays lead to the mast where the forestay attaches, the effect of tensioning them is to reduce sag in the headsail, increase mast bend, and flatten the mainsail as a result. Both effects are desirable as the wind increases.
