CliveL said "Sorry SSD, but there ain't no waisting on the fuselage, although the area ruling in that area is quite good. Did you mean where the fuselage starts to taper?"

Nope. I meant the waisting of the fuselage where the fin starts. Stand on the steps by the front door where Dude's wife took that picture, and you'll see that the cabin roof is 'waisted in' noticably where the fin is mounted (not the sides of the fuselage which remain parallel - the roof, which is bowed inwards and downwards to reduce the fuselage cross section co-incident with the fin's extension above the fuselage). I see it several times a week on OAC.
You can see it on this picture too, though it's not as obvious as when you look back from the door.
Mr Vortex - Yes, the gradual taper of the nose and of the tail help with area rule. As does the wing leading edge being brought as far forward as possible where it joins the fuselage, so the cross-sectional area increases as gradually as possible, nose to tail, at the wing root.
