Hi Erik, The baby stay has a big effect on mast bend and therefore mainsail shape, as you say. With a masthead rig, in-line spreaders and a tree trunk for a mast, the backstay has most effect on forestay tension, but does induce bend from compression and the fixed point at the partners. We crank on the babystay (including winching it to the foreward stop on the track) when we're overpowered upwind. Have a look at the shape at the dock with just backstay / with baby stay too. It's very different (on ours anyway).
It is important to remember about it at the top mark. I didn't see exactly what effect it had on the stay / mast when we tried to gybe with it taught a couple of years ago, and didn't want to...
