Superiorvoyager, you were correct to start--increasing rake, moving sail draft aft on the boat, would increase weather helm, as I think SEMIJim clarifies above.
I'm no rig tuner, by any stretch, but I would think you'd need to tighten the forestay to decrease rake noticably.
All that said, rake might not actually be the source of your weather helm problem. Weather helm means the draft of the sails is too far aft. Mast rake could cause this, but it could also be that the sails are too stretched out or not properly adjusted, resulting in mainsail draft that's moved after of where it should be. The solution if that's the case would be to have the main recut, if possible--replacement would be great too, but obviously much more $.
I would at least try sail adjustments (outhaul, leech, etc.) before pulling off the rolling furling unit to tighten the forestay. Just my two cents...
P.S...added later -- Looks like others before me have posted pretty much what I did--I took to long to submit my post!
