Re: Backstay and forestay
So far no one has mentioned a few important facts.
Is the boat in question a masthead rig or a fractional rig? A masthead rig, where the forestay goes to the top of the mast is not usually as adjustable as a fractional rig, where the forestay connects to the mast below the top of the mast. On a fractional rig, since the backstay and forestay are separated, increasing the backstay tension will bend the mast (this is done on purpose) and is used to flatten the sail in higher winds, and to ease the mast forward on downwind run to allow the spinnaker to project more to windward.
You can do the same thing on a masthead rig, but it is not as effective. You can still adjust the forestay tension to remove the curve, but you can't really bend the mast.
