Dang, you haven't even applied any cunningham yet? Definitely try all of your sail shaping tools before moving your mast around.

Yes, check your pre-bend as Rich says. Luffs are cut slightly curved, and the pre-bend helps get the luff tight. When sailing upwind in a moderate breeze, put your outhaul and cunningham on to get the sail flat and move the draft forwards. Downwind, apply some vang.

If you don't have a draft stripe, you might purchase and apply one. It'll help you see if the belly is moving forwards or not.

Bottom line- Try to pull the belly out of the sail first. It may not be blown out. Hopefully this will lessen your weather helm.

One final thought- Recently followed a thread on another forum about a fellow who had horrendous weather helm. It turns out that his rudder had hit something and the rudder shaft was bent aft a few degrees. It's amazing the difference just a few degrees made. He carefully straightened it and weather helm disappeared.

If you've seen your boat out of the water, then disregard this last part.
