Gregg,
The mast , after pre-bend, should adapt the luff curve of the sail and is not usually straight when you tension the backstay. Having a straight mast would usually induce a lot of "shape" in the sail which may not be suitable in most conditions as the wind may detach from the leeward side of the main. This is especially so at the top of the sail.
