Re: Difficulty tacking when reefed
If the single line reefing system is setup right, it should pull down and out towards the end of the boom (clew), and of course pull down at the boom end (tack). If it's rigged right, the new tack and clew should be tight to the boom, and the whole base of the sail (foot) should be tight, not baggy. If it's baggy above that point, well, maybe the sail is a bit shot....but with single line reefing I suspect a problem with single line reefing setup.
The way single line reefing is often accomplished is the line that leads to the new clew (the grommet that becomes the clew when reefed), is first tied around the boom, and then goes aft to a block. In this way the sail is pulled both down and aft, tightening the foot. I'm guessing you are not rigged right as you are describing a baggy reefed main.
That said, knuterikt's point is also correct. You might need some jib, or some pull from something forward to bring the boat around.
